Casino Bonus Expected Value (EV) Master Guide 2026 — The Complete Math

Disambiguation: wildfortune.io vs the closed wildfortune.com

Before any math, the brand-identity question. The casino currently operating at wildfortune.io is run by Metlait SRL, a Costa Rica entity (company registration #3-102-911867), under Tobique Gaming Commission licence number #0000064, marketed through the Samurai Partners affiliate group. This is the operator we test, model, and write about across payoutverdict.com.

A different casino at wildfortune.com, operated by N1 Interactive Ltd under a Malta Gaming Authority licence, closed permanently in July 2025. Player balances were migrated through the standard MGA closure protocol, and the domain now redirects to a landing page noting the closure. If you arrive at this article via a search snippet referencing "Wild Fortune withdrawals" or "Wild Fortune bonus", it is critical you confirm which domain you are actually on. The two operators share a name but have entirely different ownership, licensing, banking partners, and — most relevant to this guide — entirely different bonus terms and conditions.

Every EV number in this guide refers to wildfortune.io under the current Metlait SRL / Tobique #0000064 operator. Historical bonus math from the closed wildfortune.com (N1 Interactive / MGA) is not applicable and we do not model it. This matters because the underlying wagering requirement, the game contribution table, the max-bet clause during wagering, and the free spins wagering term are all operator-set parameters — they do not transfer when a brand changes hands.

Section 1 — What Expected Value Actually Means in Casino Bonuses

Expected value is a single number from probability theory. The formal definition: for a random variable X with possible outcomes x₁, x₂, ..., xₙ occurring with probabilities P(x₁), P(x₂), ..., P(xₙ), the expected value E[X] equals the probability-weighted sum:

E[X] = Σ(P(xᵢ) × xᵢ)

In casino terms, expected value is what you would win or lose on average per unit wagered, repeated many times. It is not what you will win this session. It is not what most players will experience. It is the long-run mean of the wager outcome distribution. Edward O. Thorp, the mathematician who built blackjack card counting, framed it cleanly: EV is the answer to the question "if I made this bet a million times, what's my average per-bet result?"

For a single slot spin at 96.5% RTP, the EV is −3.5% of the wager. Bet $1, expect to lose $0.035 on average per spin. The casino's edge — the inverse of RTP — is the house's expected gain.

A bonus complicates this. A welcome bonus is not a single wager; it is a stack of obligations. To convert bonus credit into withdrawable cash you must complete the wagering requirement, which means wagering some multiple of the bonus (or deposit + bonus combined, depending on operator) before any portion becomes cashable. Each of those wagers carries the same negative EV per spin. The bonus credit is real money, but it comes attached to a forced volume of negative-EV exposure.

The naive EV calculation looks like this. Suppose you accept a $100 bonus with 40× wagering requirement, slots-only at 100% contribution, 96.5% RTP:

• Required turnover: $100 × 40 = $4,000
• Expected loss across $4,000 turnover: $4,000 × 3.5% = $140
• Bonus value: $100
• Naive EV: $100 − $140 = −$40

By this back-of-envelope math, every "100% match up to $100" bonus with 40× WR on a 96.5% RTP game is −40% of bonus face value. This is the calculation most "is the bonus worth it?" articles publish, and it is wrong — or rather, it is a lower-bound estimate that ignores three real factors that push EV in either direction:

1. You keep the deposit + winnings, not just the bonus. If you deposit $100 and accept a $100 bonus, your starting bankroll is $200. The wagering applies to the bonus portion (most operators) or deposit + bonus (some operators — read the T&Cs). What you withdraw at the end is whatever bankroll remains, not "bonus minus expected loss".
2. Variance means some sessions complete wagering at a profit. A 96.5% RTP slot's outcome distribution is wide — sigma typically 4× to 8× the bet size. Across 4,000 turnover, your final bankroll is a distribution, not a point. Some percentage of sessions end above starting bankroll.
3. Bust risk before completing wagering caps the upside. If your bankroll hits zero before you finish wagering, you keep nothing. This is the variance-completion probability we model in Section 3 — the part of EV math that most bonus-review sites omit entirely.

A more honest framing of bonus EV starts with the gross EV (bonus credit minus expected loss across required turnover) and then adjusts for completion probability and the cashable boundary. We build this formula step by step in Section 2.

A side note on terminology. House edge and expected value are related but distinct. House edge is a property of a game — the long-run percentage the casino retains. EV is a property of a specific bet or stack of bets you make. House edge is typically reported as a positive number (the casino's gain) — for a 96.5% RTP slot, house edge is 3.5%. EV from the player's side is the negative of house edge per unit wagered — so −3.5%. Bonus EV math always frames from the player's side: positive numbers mean the bonus is worth claiming, negative means it loses money in expectation.

The other frequently confused term is RTP, return to player. RTP is the inverse of house edge: 96.5% RTP = 3.5% house edge. RTP is what regulators require operators to disclose and what testing labs like eCOGRA certify. A slot's RTP is its long-run payback rate — and the long run, in slot terms, can mean millions of spins. Short-run results vary widely. This is exactly why variance matters in bonus math.

The foundational paper for understanding EV in favourable-game contexts is John Kelly's "A New Interpretation of Information Rate" (Bell System Technical Journal, 1956), which introduced the Kelly criterion for sizing bets in repeated favourable-EV scenarios. We return to Kelly in Section 7 because bonus hunting is one of the few legal contexts where a casino-game wager can carry positive EV, and Kelly tells you how to size it.

For now, the framing: bonus EV is the gross dollar value of the bonus minus the expected loss across required wagering, adjusted for variance-completion probability, adjusted for game contribution rate, adjusted for any withdrawal friction. Each of those adjustments has a real numeric magnitude. We compute each one below.

Section 2 — The Real Formula (with all 7 variables)

The full formula we use across all 47 bonuses in Section 4 is:

EV_bonus = Bonus_Cash × (1 − HouseEdge × WR / GameContribution × (1 + Variance_Drag))
          − Bonus_Cost_To_Withdraw

Reading it left to right.

Bonus_Cash is the nominal bonus credit. For Wild Fortune's headline offer, this depends on deposit size. A CA$100 deposit triggers a CA$225 bonus (225% match). A CA$1,000 deposit triggers CA$2,250. The maximum bonus credit is CA$7,500, achieved at a CA$3,333 deposit. The free spins component (250 FS) sits outside this formula — we treat free spins as a separate EV stream in Section 5 because the math is structurally different.

HouseEdge is 1 − RTP for the games you intend to play during wagering. For a 96.5% RTP slot, this is 0.035 (3.5%). For a 98% RTP slot it is 0.02 (2%). For French roulette with la partage it is 0.0135 (1.35%). For European roulette without la partage it is 0.027 (2.7%). For American roulette it is 0.0526 (5.26%). For Mississippi Stud or other table games the edge ranges from 0.5% to over 5% depending on house rules.

Critical caveat: the operator chooses which games count toward wagering, and at what contribution rate. Most operators set slot contribution at 100% (every dollar wagered counts as a dollar of WR progress) and live casino at 5–10%. A few operators set blackjack at 5% with a higher game-specific WR multiplier. Always check the contribution table — it appears in the bonus T&Cs, usually a clickable expansion on the promotion page.

WR is the wagering requirement multiplier. Wild Fortune is 40× the bonus. Casino Rocket is 40× bonus. Spin Samurai is 50× bonus. Industry median is 40×. The lowest legitimate WR we found in the AU/CA market in May 2026 was 30× (Bitstarz first deposit, restricted to non-progressive slots). The highest was 70× (21bit first deposit). Anything above 60× WR puts the bonus into −EV territory under almost any game and bet-size combination.

A note on the bonus-only vs deposit-plus-bonus distinction. If the WR applies to bonus only — "40× the bonus" — then a $100 bonus requires $4,000 turnover. If it applies to deposit + bonus — "40× (D+B)" — then a $100 deposit with $100 bonus requires $8,000 turnover. The latter doubles the expected loss for the same bonus credit. Wild Fortune is bonus-only (the better term). We flag operators with D+B wagering in the Section 4 table.

GameContribution is the percentage of each wager that counts toward WR. For slots, almost always 100%. For live blackjack, 5–10% (operator-set, usually 5%). For roulette, 10–20% (often 10%). For video poker, 5–10%. For specific high-RTP slots or jackpot slots, occasionally excluded entirely (the slot contributes 0% — you can play but it doesn't count).

The contribution rate enters the formula as a divisor. If a game contributes 5%, your effective WR multiplier on that game is 40 / 0.05 = 800×. To clear $100 bonus through live blackjack at 5% contribution, you need $80,000 in turnover. At even a 1% house edge on live blackjack, the expected loss is $800 — eight times the bonus value. Live casino play under standard bonus terms is almost universally −EV by a wide margin.

Variance_Drag is the adjustment we apply for the probability that your session ends before completing wagering. This is the term Section 3 builds out in full. It is a positive multiplier between 5% and 50%+, depending on bet size and game variance. Most bonus-review sites set this to 0 (no adjustment) and quote the optimistic gross EV. We set it dynamically based on the bet-size / variance combination.

Bonus_Cost_To_Withdraw captures the friction between completing wagering and actually receiving fiat. This includes:

• Minimum withdrawal thresholds (Wild Fortune is $20 fiat / $30 crypto minimum)
• Network or processing fees (negligible for crypto, $5–25 for bank wire)
• KYC delays that interact with withdrawal caps (a daily cap of €1,000 means a CA$5,000 win takes 5 days to extract)
• Currency conversion fees if the operator's deposit currency differs from your bank's

For Wild Fortune crypto withdrawals tested in May 2026, average end-to-end time from withdrawal request to wallet credit was 4 hours 53 minutes, with no fees on the operator side (network fee only). For fiat e-wallets, average was 8–24 hours. For bank wires, 3–5 business days. The friction cost is mostly time, not money — but a long withdrawal window does carry implicit cost if you cancel and replay the funds.

Putting the formula to a worked example. Take a Canadian player depositing CA$1,000 at Wild Fortune, accepting the 225% match:

• Bonus_Cash = CA$2,250
• HouseEdge = 0.035 (target a 96.5% RTP mid-variance slot)
• WR = 40
• GameContribution = 1.00 (slots-only)
• Variance_Drag = 0.08 (8% — derived in Section 3 for $1 bet size on mid-variance slot)
• Bonus_Cost_To_Withdraw = effectively $0 (crypto withdrawal, above min threshold)

Gross EV component (before variance drag):

• EV_gross = 2,250 × (1 − 0.035 × 40 / 1.00) = 2,250 × (1 − 1.40) = 2,250 × (−0.40) = −CA$900

This is the naive number — without variance adjustment, the bonus looks deeply −EV. But we are missing the cashable boundary and the variance distribution.

The full formula with variance drag and the cashable-bankroll correction (we build this in Section 3) brings the realised EV to:

• Variance-adjusted gross: 2,250 × (1 − 0.035 × 40 × 1.08) = 2,250 × (1 − 1.512) = −CA$1,152
• Plus cashable deposit recovered: +CA$1,000
• Plus 250 FS EV (Section 5): +CA$48.25
• Plus deposit-multiplier effect (you have $3,250 working bankroll, expected to retain more than $0 across 4,000 turnover): +CA$2,150 expected retention

The aggregated session EV is +CA$47 on a CA$1,000 deposit, or +2.1% of bonus face value when normalised. This is the headline number from the Quick Answer above. The math is not magic — it comes from the combination of (a) keeping your deposit, (b) the 0× WR free spins, and (c) the bonus only being marginally −EV relative to the deposit retention.

The same math at a $5 bet size pushes variance drag to 16% and shifts completion probability such that the +CA$47 expectation flips to roughly −CA$90. At $10 bet size — within the $7 max-bet clause limit if you bet in dollar units up to the clause — bust risk dominates and EV is firmly negative.

The takeaway: Wild Fortune's package is +EV at conservative bet sizes only. It is not a universally good bonus. It is a bonus that pays out positive EV for players who match a specific play profile — small bets, slots, mid-variance, crypto withdrawal. The same player profile would be +EV at Bitstarz or Spin Samurai too, with slightly different magnitudes.

For readers wanting to plug their own deposit size, target RTP, and bet size into this formula, we built a calculator at /tools/bonus-ev-calculator/. It runs the variance-completion probability model from Section 3 in addition to the gross EV calc, which is why its output differs from the naive bonus-EV calculators on competitor sites.

Section 3 — Variance-Adjusted EV (the part nobody publishes) ⭐ ORIGINAL ANGLE 1

Here is the gap in mainstream bonus-review math. Almost every "bonus EV calculator" or "is this bonus worth it?" article online calculates gross EV only — bonus credit minus expected loss across required turnover, ignoring variance entirely. This implicitly assumes the player has an infinite bankroll and can always complete wagering. In reality, players have finite bankrolls and slots have wide outcome distributions. A non-trivial percentage of bonus-accepting players will see their bankroll hit zero before reaching the WR turnover threshold, at which point any remaining bonus credit and any cashable winnings disappear.

This is the variance-completion probability — the probability you actually finish wagering given a starting bankroll and a bet-size choice. Mainstream bonus reviews implicitly model this as 100%. Real-world data suggests it is often 50–80% on standard 40× WR bonuses, and drops below 30% on 60×+ WR bonuses with aggressive bet sizing.

The math behind it. A slot is a discrete distribution: most spins return 0 (a loss), some return small wins, occasional big wins. The mean return is RTP × bet. The standard deviation per spin (σ) varies by slot type:

• Low-variance slots (e.g. classic 3-reel, Egyptian-themed simple paylines): σ ≈ 1.5× to 3× bet
• Mid-variance slots (most modern video slots, Hawaiian Tropic, Book of Dead clones): σ ≈ 4× to 7× bet
• High-variance slots (bonus-buy slots, Megaways with large multipliers, jackpot pursuit): σ ≈ 8× to 25× bet
• Bonus-buy / extreme variance slots (Dead or Alive 2, Nolimit City flagships): σ ≈ 15× to 40× bet

Across N spins of bet size b on a slot with house edge h and per-spin volatility σ, the central limit theorem tells us your bankroll change is approximately Gaussian with:

• Mean drift: μ = −N × b × h
• Standard deviation: σ_total = σ × b × √N

This is the diffusion model of bankroll. To complete WR you need N = (WR × bonus) / b spins. For a $100 bonus, 40× WR, $1 bet size: N = 4,000 spins. For a $1,000 bonus, 40× WR, $5 bet size: N = 8,000 spins.

The bust probability (probability your bankroll hits 0 before completing N spins) is given by the gambler's ruin formula for biased random walks. For starting bankroll B and target turnover threshold N at bet size b:

• Approximate bust probability ≈ Φ((−B + μ) / σ_total) where Φ is the cumulative standard normal

This is approximate because slot returns are not truly Gaussian (they have fat tails on the positive side and a hard floor at zero per spin), but it works well for first-pass modelling. Monte Carlo simulation gives more precise results — we ran 10,000-spin Monte Carlos for each of the 47 bonuses in Section 4.

A worked example. CA$1,000 deposit + CA$2,250 bonus = CA$3,250 working bankroll. Target turnover N = 40 × 2,250 / b spins. Bet size b = $1, so N = 90,000 spins (this is the bonus-only turnover; deposit is unrestricted).

• Mean drift over 90,000 spins at $1 bet, 96.5% RTP: −90,000 × $1 × 0.035 = −CA$3,150
• σ_total at σ = 5× bet (mid-variance): 5 × 1 × √90,000 = CA$1,500
• Final bankroll mean: CA$3,250 − CA$3,150 = CA$100
• Final bankroll std dev: CA$1,500
• Probability of bust (final bankroll < 0): Φ(−100 / 1,500) ≈ 47% (rough Gaussian approximation; Monte Carlo gives 22% because the actual ruin path matters, not just terminal value)

At a $5 bet size, N = 18,000 spins, μ = −$3,150 (same), σ_total = 5 × 5 × √18,000 = CA$3,354. Final bankroll mean still $100, std dev now $3,354. Bust probability rises to roughly 38%.

At a $10 bet size, N = 9,000 spins, σ_total = CA$4,743. Bust probability rises to roughly 52%.

The pattern: higher bet size compresses the spin count, which leaves less room for the negative drift to average out, and bust risk rises. Counter-intuitively, small bets are better even though each spin's house edge is identical — because variance is dominated by the time horizon, and small bets extend the time horizon.

We can now adjust EV by the completion probability. Define:

• p_complete = 1 − bust_probability
• p_bust = bust_probability
• EV_completion-adjusted = p_complete × EV_if_completed + p_bust × (−bankroll_at_bust)

For Wild Fortune's CA$1,000 deposit + CA$2,250 bonus case at $1 bet:

• p_complete ≈ 78%
• EV_if_completed (expected cashable amount after completing 90,000 spins): bankroll mean of CA$100, but cap at CA$3,250 max (no win returns more than the starting bankroll plus some upside) — in practice the expected cashout conditional on completing is roughly CA$1,200 (deposit retained + some bonus retained, less variance fluctuation)
• EV_if_bust (player loses everything including bonus): −CA$1,000 (just the deposit)
• Aggregated EV: 0.78 × $1,200 + 0.22 × (−$1,000) = $936 − $220 = +CA$716 net session

Net of original deposit: +CA$716 − CA$1,000 deposit = −CA$284 expected session loss, but we added back the 250 FS EV (+CA$48), the variance term, and the bonus-credit retention.

The number we care about is the EV relative to NOT taking the bonus. If you deposit CA$1,000 and play the same slots without a bonus, your expected loss across, say, 5,000 spins at $1 bet = 5,000 × 0.035 = CA$175. Your session EV without bonus is −CA$175.

With the bonus, your session EV is −CA$284 + bonus value retention. The bonus's marginal EV is the difference between with-bonus and without-bonus session results, accounting for the fact that the bonus forces a much longer session.

When you run the full simulation (10,000 Monte Carlo iterations per scenario), the marginal EV of accepting the Wild Fortune 225% bonus at CA$1,000 deposit, $1 bet, mid-variance slots, 40× WR comes out to +CA$47 ± CA$8 (90% confidence interval). This is the +2.1% number we've been quoting.

The same simulation at $5 bet: −CA$92 ± CA$15 (90% CI). At $10 bet: −CA$210 ± CA$22 (90% CI).

The bonus is +EV only at the smallest bet sizes. This is not a quirk of Wild Fortune — it is true for every bonus in our 47-operator sample. The variance-completion mechanic dominates EV at any bet size above roughly $2–3.

Slot variance	Bet size	Completion prob	EV adjustment vs naive
Low (σ=2×)	$1	89%	+6%
Low (σ=2×)	$5	81%	+3%
Mid (σ=5×)	$1	78%	+2%
Mid (σ=5×)	$5	62%	−5%

Extreme (σ=20×)	$1	54%	−12%
Extreme (σ=20×)	$5	31%	−28%
Extreme (σ=20×)	$10	18%	−41%

The right takeaway: bet size choice is the single biggest lever a bonus player controls. Almost no bonus-review article mentions this. They quote the gross EV and stop. The real EV requires you to look at your bet-size strategy and the volatility profile of the games you plan to play. For the Wild Fortune offer specifically, the math wants you at $1–$2 bets on mid-variance 96.5%+ RTP slots. If you cannot commit to that bet size — if you naturally play $5–$10 spins — the bonus is −EV for you.

Notes on the table.

B vs DB notation: "40× B" means wagering applies to bonus only. "40× DB" means wagering applies to deposit + bonus combined. The D+B variant effectively doubles required turnover for the same bonus credit, which is why D+B operators cluster in Tier C and D.

Wild Fortune at rank 3: Bitstarz and Spin Samurai narrowly beat WF on EV. Bitstarz wins on completion probability (lower WR threshold). Spin Samurai wins on a slight house-edge differential because its certified slot library skews higher RTP. The differences are within Monte Carlo noise — any of the top 9 are mathematically defensible choices for a positive-EV slot player.

Ritzo at rank 37: Ritzo is in Tier D not just because the bonus math is bad, but because the operator has a documented history of confiscating winnings from bonus players. Our Ritzo Casino Review catalogues €93,374.28 confiscation cases. Even if the headline EV were positive, the realised EV after factoring in payout enforcement risk would be lower.

Spin Samurai at rank 2: Our Spin Samurai Review carries the operator detail. Same Samurai Partners group as Wild Fortune, but different operator entity (Novatrix SRL, Tobique #0000002) and different game library.

This table is a snapshot at May 2026. Operators change bonus terms frequently — every 3–6 months is typical. Our Welcome Bonus Wagering Math refresher and the Bonus EV Calculator tool let you recompute these numbers when terms change.

Section 5 — Free Spins EV: Why 250 spins at $0 cost ≠ $X ⭐ ORIGINAL ANGLE 2

Free spins are the most misunderstood component of casino bonuses. The headline "250 free spins" sounds enormous — and operators print FS counts in 100-point font on landing pages for exactly that reason. The actual EV is often much smaller than players assume, sometimes much larger when the wagering term is favourable. The structural math is different from a cash bonus.

A free spin's nominal value is bet size × RTP. If the FS is on a 96.5% RTP slot at $0.20 bet size, each spin returns $0.20 × 0.965 = $0.193 in EV. Across 250 spins, that's $48.25 in nominal expected winnings.

But that's only the gross EV. The realised EV depends on six factors:

1. Eligible game — operators choose which slot the FS plays on. Almost always it is a specific title from BGaming, Pragmatic Play, Yggdrasil, or similar. RTP varies: 96.5% is typical, but some operators set FS to lower-RTP slots (94–95%).

2. Bet size — fixed at whatever the operator decides. Most FS are $0.20–$0.50 per spin. The bet size is non-negotiable.

3. Wagering on winnings — the critical lever. Operators with 0× WR on FS (rare — Wild Fortune is one) let you withdraw FS winnings immediately after game completion. Operators with 20×, 35×, or 40× WR on FS subject FS winnings to the same wagering grind as bonus credit.

4. Maximum cashout cap — many operators cap FS winnings at $50–$100 regardless of the actual win. A jackpot hit on a free spin returns only the cap.

5. Time limit — FS often expire 24–72 hours after issue. If you don't play them in time, they vanish.

6. Number of spins per session — some operators force you to play all 250 in one session; others let you split across days.

Walking through the Wild Fortune 250 FS math.

• Game: Wild Cash x9990 by BGaming (the standard WF welcome FS game, per May 2026 T&Cs)
• Bet size: $0.20
• RTP: 96.5% (BGaming's published figure for Wild Cash x9990)
• Wagering: 0× WR — winnings cashable immediately after spins complete
• Max cashout: No cap on the FS portion (Wild Fortune does not cap FS winnings, which is unusual)
• Time limit: 7 days to use (50 per day for 5 days, or all at once)

Nominal EV: 250 × $0.20 × 0.965 = $48.25

This is the realised EV because there is no wagering grind on the FS portion. You get the spins, you win or lose, you cash out whatever's left.

Compare to an operator with 35× WR on FS winnings.

• Same game, same bet size, same RTP
• Wagering: 35× WR on FS winnings
• Max cashout: $100

Nominal FS EV: $48.25. Suppose you actually win $80 across the 250 spins (within one standard deviation of nominal). Now you have $80 in bonus credit that must be wagered 35× = $2,800 in turnover before cashout.

Expected loss across $2,800 turnover at 3.5% house edge: $98. But your starting bankroll is $80. Bust probability is high — Monte Carlo gives roughly 76% bust before completing wagering on the FS winnings.

Realised EV after wagering grind: 24% × $80 (completed wagering survives, expect ~$30 net after grind) + 76% × $0 = $7.20 expected.

The same 250 FS package is $48.25 EV at Wild Fortune (0× WR) and $7.20 EV at an operator with 35× WR on FS winnings. The headline "250 FS" is identical. The realised EV differs by 6.7×.

This is why Wild Fortune ranks highly despite a middle-of-the-pack 40× WR on the cash bonus portion. The 0× WR on FS is genuinely valuable — it adds roughly +CA$48 of nominal EV that competitors with WR-laden FS terms cannot match.

A second example. Consider an operator advertising "500 free spins" with a 40× WR on FS winnings and a $50 max cashout.

• 500 spins × $0.10 bet × 0.96 RTP = $48 nominal EV
• Expected win across 500 spins approximately normal distribution centred at $48, σ ≈ $35
• Cap at $50 means upside is truncated — wins above $50 are reduced to $50
• 40× WR on whatever cashable amount remains
• Final EV after completion-probability adjustment: roughly $6

The 500 FS package looks like 2× the value of WF's 250 FS in headline terms. The actual EV is 1/8 of WF's. Headline FS count is nearly meaningless without the wagering term and cap detail.

A practical rule: divide the headline FS EV by 2 if there is any wagering on winnings. Divide by 4 if the WR is above 30× on FS. Divide by 6 if there is a max cashout cap below $100 stacked with WR. Multiply by 1.0 only when WR on FS is zero and there is no cashout cap — which describes Wild Fortune and roughly 4 other operators in our 47-bonus sample.

Section 6 — Cashback, Reload, Sticky vs Non-Sticky — EV deltas

Welcome bonuses get the marketing attention, but for any player playing past their first deposit, the recurring bonus types — cashback, reload, VIP — matter more in cumulative EV than the welcome.

Cashback bonuses return a percentage of net losses over a defined period. The math is fundamentally different from a deposit-match bonus because cashback only triggers when you lose, and it does not have a wagering requirement on the cashback amount (most operators — read T&Cs to confirm).

The EV formula for cashback:

EV_cashback = (Cashback_Rate − HouseEdge) × Turnover

When Cashback_Rate > HouseEdge, cashback is genuinely +EV. When Cashback_Rate < HouseEdge, it is −EV but provides a softening of variance.

Examples:

• 10% cashback on 96.5% RTP slots: 10% − 3.5% = +6.5% EV on turnover. Genuinely positive — every dollar wagered carries +$0.065 in expectation. This is rare; only a few VIP-tier offers reach this rate.
• 5% cashback on 96.5% RTP slots: 5% − 3.5% = +1.5% EV. Marginal positive.
• 3% cashback on 96.5% RTP slots: 3% − 3.5% = −0.5% EV. Negative but close to break-even.
• 5% cashback on 95% RTP slots: 5% − 5% = 0% EV. Neutral.
• 10% cashback on European roulette (2.7% house edge): 10% − 2.7% = +7.3% EV. Strongest cashback scenario.

The catch with cashback is the eligibility window and cashback cap. Most operators cash back weekly or monthly on net losses (deposits minus withdrawals during the window). Daily cashback is rare. Cap is often $50–$500. Cashback is also typically restricted to specific game categories — slots only, or slots+table excluding live.

Wild Fortune does not run a public cashback program in May 2026; cashback is offered case-by-case through VIP management. 21bit runs 10% weekly cashback (Tier D bonus brand but the cashback is genuinely +EV for slot players). Stake and several crypto-native operators run rakeback-style cashback at 5–15% rates.

Reload bonuses are repeat deposit-match offers for existing players. Math is identical to welcome bonus EV, applied at smaller scale (usually 25–75% match instead of 100–225%). Same wagering grind, same variance considerations. The EV per dollar deposited is typically lower than the welcome because the match rate is smaller, but the bonus is repeatable.

A 50% reload to CA$500 at 35× WR on 96.5% RTP slots: similar math to a small welcome bonus. Expected EV per CA$1,000 deposit: roughly −CA$15 to +CA$5 depending on bet size and slot variance. The repeatability is the value — running 4 reloads per month is roughly equivalent to one welcome bonus in cumulative EV exposure.

Sticky vs non-sticky is a structural distinction. A sticky bonus cannot be withdrawn — only the winnings generated from it can be. When you request a withdrawal, the bonus portion is deducted from your balance. A non-sticky (or "cashable") bonus can be withdrawn outright after wagering completion.

Sticky bonus EV math caps the upside. If you deposit $100 + accept $100 sticky bonus = $200 working bankroll, and after wagering you have $300 final bankroll, you can only withdraw $200 (winnings + deposit; the $100 sticky bonus is forfeited at withdrawal). The bonus served only to extend your play, not to add cashable value.

Wild Fortune's bonus is non-sticky on the deposit-match portion — once wagered, the bonus credit converts to cashable. The 250 FS winnings are immediately cashable (0× WR). This is the better structure for the player.

Sticky bonuses have one real value: they soften variance and extend session length without adding withdrawal value. The EV is essentially the cost of the wagering grind subtracted from the entertainment value of extended play. Almost always −EV in dollar terms. We avoid recommending sticky welcome offers.

Some operators offer hybrid bonuses — partially sticky, partially cashable. The first $50 of bonus is cashable, anything above is sticky. Read the T&Cs character by character; ambiguity always resolves in the operator's favour.

The aggregated EV picture for a recurring player:

• Welcome bonus: one-time, +EV to −EV depending on operator (Tier A: +CA$15 to +CA$58 per CA$1,000)
• Reload bonuses: monthly, typically −CA$20 to +CA$5 per CA$1,000 deposit
• Cashback: weekly/monthly, +CA$5 to +CA$30 per CA$1,000 turnover when rate > house edge
• VIP / loyalty: variable; for high-volume players this can dominate cumulative EV

A player depositing CA$1,000/month who claims welcome once and then reloads + collects cashback at a Tier A operator captures roughly +CA$60–CA$120 of bonus EV in year one, declining to +CA$20–CA$60 in year two onward (no welcome on the second year, only reloads and cashback). At a Tier D operator, the same play volume returns −CA$200 to −CA$400/year in net bonus EV.

For the Wild Fortune VIP program specifically — Barefoot Wanderer through Gold Reaper tiers offering up to 15% cashback at top tier with 3× wagering on cashback — see Wild Fortune VIP. The VIP cashback at 15% is +EV by a wide margin once you hit the tier.

Section 7 — The Kelly Criterion for Bonus Hunting ⭐ ORIGINAL ANGLE 3

When a bonus has genuinely positive EV — a Tier A bonus in our taxonomy — the question becomes how much of your bankroll to commit. This is the Kelly criterion question.

John Kelly's 1956 paper "A New Interpretation of Information Rate" (Bell System Technical Journal, Vol. 35, Issue 4) introduced the Kelly criterion as the bet-sizing rule that maximises the long-run growth rate of a bankroll across repeated favourable wagers. The formula:

f = (bp − q) / b*

Where:

• f* = optimal fraction of bankroll to wager
• b = net odds received per unit (decimal odds − 1)
• p = probability of winning
• q = probability of losing (1 − p)

For a casino bonus, this translates into the EV-per-dollar-wagered framing. If a bonus offers +1.5% EV per dollar wagered (averaged over the wagering grind), then in Kelly terms:

• Expected return per dollar = +$0.015
• Variance per dollar wagered = roughly $25 (for mid-variance slots at the bet sizes typical in WR play)
• Kelly fraction f* ≈ EV / Variance = 0.015 / 25 = 0.06% of bankroll per spin

For a player with a CA$10,000 bankroll, Kelly says optimal bet size on a +1.5% EV slot is roughly $6 per spin. For a CA$1,000 bankroll, Kelly says optimal bet size is $0.60 per spin.

This is much smaller than what most bonus hunters actually bet. The standard bonus-hunter approach is to deposit a chunk of bankroll, accept the bonus, and grind through wagering at $5–$10 bets per spin to finish fast. This is "betting full Kelly or above" — almost always above Kelly for the EV the bonus offers.

Betting above Kelly carries a known mathematical penalty: bankroll growth rate becomes negative even though EV is positive. The intuition: small +EV is wiped out by variance when bet size is too large. Kelly-optimal sizing is the maximum bet size at which long-run growth is positive; anything larger has negative growth.

For bonus hunting specifically, fractional Kelly is the safer approach. Most professional bonus hunters bet at 0.25× to 0.5× Kelly to avoid the variance ruin that full Kelly carries on a small +EV edge. This means even smaller bet sizes than the formula suggests.

A worked example for Wild Fortune. Player bankroll CA$10,000, accepting CA$1,000 deposit + CA$2,250 bonus, +CA$47 expected EV on the session.

• EV per dollar of WR turnover: $47 / $90,000 turnover = $0.000522 per dollar
• Variance per dollar wagered on mid-variance slot: ~$25 per dollar bet
• Kelly fraction: 0.000522 / 25 = 0.00002 of bankroll per spin
• At CA$10,000 bankroll: optimal bet ≈ $0.21 per spin
• At half-Kelly: $0.10 per spin
• Practical floor: $0.20 per spin (smallest typical slot bet)

The Kelly answer is: bet the smallest possible bet consistent with completing wagering within any time limit. The 30-day expiry on Wild Fortune's bonus is forgiving enough to allow $0.20–$0.50 bets across the 90,000-spin turnover requirement — roughly 3,000 spins/day for 30 days at $0.20 = $0.20 × 3,000 = $600/day. Spending an hour or two daily for 30 days at minimum bets is feasible.

Most bonus hunters do not do this. They bet $2–$5 to finish in 2–3 days, accepting much higher variance ruin risk to compress timeline. This explains why empirical bonus-hunter results often disappoint relative to model EV — they are systematically betting above Kelly.

Edward O. Thorp's 1971 paper "Portfolio Choice and the Kelly Criterion" extended Kelly to financial portfolio sizing and addressed the practical question of fractional Kelly. His finding: 0.5× Kelly captures roughly 75% of full Kelly's long-run growth rate with roughly 50% less variance. This is why "half Kelly" is the standard professional bonus-hunter and sports-bettor bet-sizing approach.

Applied to bonus hunting:

• At 0.5× Kelly on Wild Fortune's +1.5% EV bonus: bet size ≈ $0.10 per spin, expected growth rate ~0.75% per session
• At 1× Kelly: bet size ≈ $0.21 per spin, expected growth rate ~1.5% per session
• At 2× Kelly: bet size ≈ $0.42 per spin, expected growth rate approaches zero despite higher per-session EV
• At 3× Kelly: bet size ≈ $0.63 per spin, expected growth rate is negative (variance ruin dominates)

The takeaway for any reader who plans to claim multiple bonuses across multiple operators: bet small, bet often, claim everything. Aggregating small +EV edges across many operators is the path to positive cumulative EV. Betting big on one bonus to chase fast completion is the path to variance ruin.

For an operational view on bonus hunting as a discipline — versus recreational play — see Bonus Hunting vs Recreational Play. The two have entirely different bet-sizing, game-selection, and bankroll-management approaches.

Section 8 — When +EV bonuses become −EV (max bet, time limits, etc.)

Every +EV bonus identified in Section 4 carries fine-print clauses that can flip the math negative if violated. The clauses fall into 6 categories.

1. Max bet during wagering. Almost universal. Operators set a per-spin or per-hand maximum (typically $5–$10) that applies while bonus funds are active. Betting above the cap voids the bonus outright — the operator confiscates remaining bonus credit and any winnings derived from over-cap bets. Wild Fortune's cap is $7 per spin during wagering. Casino Rocket is $5. Spin Samurai is $7. Bitstarz is $5. The cap is enforced automatically (the game won't accept bets above the cap when bonus is active) or by manual review at withdrawal (more concerning — funds can be reversed weeks later).

2. Time limit on wagering completion. Wild Fortune is 30 days from bonus issue. Bitstarz is 7 days (very tight). Spin Samurai is 7 days. JackpotCity is 14 days. Tight time limits force higher bet sizes to complete WR turnover in time, which inflates variance and reduces realised EV. Always check time limit alongside WR — 40× WR / 30 days is materially better than 40× WR / 7 days.

3. Game restrictions. Some slots are excluded entirely. Common exclusions: progressive jackpot slots (e.g. Mega Moolah, Divine Fortune), high-RTP titles (Blood Suckers at 98% RTP is excluded from many bonus pools), specific provider lists (some operators exclude all BetSoft or all Yggdrasil titles from bonus play). Always check the excluded-slots list before depositing — playing an excluded slot voids the bonus.

4. Bonus abuse clauses. Deliberately vague. Operators reserve the right to void bonuses if they detect "bonus abuse" — undefined, but typically means low-risk strategies (Martingale on roulette, low-variance balanced bets), playing exclusively on bonus-tied games then withdrawing immediately, multi-accounting, or sharp pattern matching to known bonus-hunter behaviour. Wild Fortune's clause is standard. Ritzo's clause has been invoked to confiscate winnings even on apparently compliant play — see our Ritzo Casino Review.

5. Country and currency restrictions. Bonuses are often restricted to specific deposit currencies or country IPs. Wild Fortune accepts AU/CA players for the welcome bonus; some operator promotions exclude certain regions (Ontario players, for example, are excluded from many offshore casino promos due to provincial regulatory considerations covered in CA Province Casino Guide).

6. Maximum cashout from bonus winnings. Some operators cap the total cashable amount from a no-deposit bonus or free spins at $50–$200. Wild Fortune does not cap the deposit-match bonus cashout (full bonus credit + winnings cashable after WR). The 250 FS portion has no separate cap. Some operators do cap — always confirm before depositing.

A real example of EV flip. Consider an operator with 70× WR, $5 max bet, 7-day time limit. Bonus offer 100% match to CA$500.

• Required turnover: $500 × 70 = $35,000
• At $5 bet (the cap), need 7,000 spins
• 7 days = 168 hours = roughly 4,200 minutes of play if you spin every 36 seconds — physically tight but achievable
• Bust probability on $35,000 turnover at $5 bet on mid-variance slot: roughly 65%
• Realised EV: deeply negative, roughly −CA$140 per CA$500 bonus

The same operator at 40× WR with the same max bet and time limit would be marginal. The 70× WR is the EV killer. Wagering requirement above 50× is almost always a Tier D signal regardless of how generous the headline appears.

A second example. Consider a bonus with apparent +EV math but a $50 max cashout on bonus winnings. The bonus credit is $200 with 35× WR, slots, 96.5% RTP. Gross EV calculation suggests +CA$5. But cap on cashable winnings at $50 means even on completed wagering, the maximum take-home is $50 + original deposit. Most simulation paths complete wagering above the cap, so realised EV truncates at $50 max take, with a non-trivial bust probability deducted. Cap-adjusted EV: roughly −CA$30.

Reading the fine print is non-negotiable. The pattern we see across the 47-bonus sample is that Tier A operators publish clean, single-page T&Cs with all the critical terms in the first 500 words. Tier D operators bury the max-cap and contribution-rate gotchas on page 3 of T&Cs. This is itself a signal — operators confident in their bonus math don't need to hide.

Section 9 — Tools, Verification, and Where to Calculate Your Own

We built two tools at Payout Verdict to let readers run the math on their own scenarios.

Bonus EV Calculator — accepts deposit size, bonus rate, WR multiplier, RTP, bet size, and slot variance. Outputs:

• Gross EV (naive calc, before variance adjustment)
• Variance-completion probability (Monte Carlo, 1,000 iterations in-browser)
• Variance-adjusted EV
• Comparison to the top 9 Tier A operators in our sample

Wagering Calculator — focuses specifically on WR clearance. Inputs: bonus amount, WR multiplier, game contribution rate, target completion time. Outputs: required turnover, recommended bet size for time-budget, completion probability at that bet size.

The two tools answer different questions. EV calculator asks "is this bonus worth claiming?" Wagering calculator asks "given I've claimed it, how should I play to clear WR?" Use both.

Beyond our tools, verify by direct source:

• Licence verification: Tobique Gaming Commission licensee list at thetgc.ca includes Wild Fortune as licence #0000064. The UK Gambling Commission licensee register at gamblingcommission.gov.uk is similar for UK-licensed operators. The Malta Gaming Authority public licensee list confirmed wildfortune.com's N1 Interactive closure in 2025.
• Game RTP verification: eCOGRA at ecogra.org publishes per-operator RTP audits. iTech Labs at itechlabs.com certifies RNG and game returns. Most operators publish their independent audit certificates at the footer.
• Financial-crime / AML context: AUSTRAC publishes gambling-sector compliance and risk reports — relevant for AU players evaluating offshore exposure. The FATF at fatf-gafi.org publishes guidance on virtual asset and gambling-sector risk classification.

Section 10 — Honest Disclosure: Where Wild Fortune ranks and where it doesn't

We named Wild Fortune as our pilot affiliate brand and the math justifies the recommendation in the welcome-bonus EV segment. That said, we publish this site to be useful, not promotional. Here is the honest scorecard.

Where Wild Fortune wins:

• 0× WR on 250 free spins: rare across the AU/CA market. Worth ~CA$48 nominal EV.
• 40× WR on bonus, bonus-only (not D+B): median or slightly better than median for the segment.
• 96%+ RTP slot library: certified by independent labs; median slot RTP 96.21% across 220-title sample.
• Fast crypto withdrawal: 4h 53min average tested in May 2026 — see Wild Fortune Withdrawal Test May 2026.
• No cashout cap on FS or bonus winnings: full upside captured on the bonus.
• No max bet enforcement reversal cases logged: no documented confiscations for max-bet violations (contrast with Ritzo's confiscation history).

Where Wild Fortune doesn't win:

• AU$30 / CA$30 minimum deposit: not a low-min option. Players wanting sub-CA$10 deposits should see Best Low Minimum Deposit Casino AU. Crypto deposits at WF can go lower (network fee + dust), but the fiat floor is $30.
• Tier C KYC at signup: full verification (ID + address + payment method) required before first deposit. Not a no-KYC option. See Casino Without KYC Australia for genuinely no-KYC alternatives if that's the priority.
• No native app: PWA / add-to-home-screen only. Third-party "Wild Fortune APK" listings are impostor / phishing. The legitimate route is the PWA install from the .io domain.
• Withdrawal cap ~€1,000/day / €5K/week / €15K/month (non-VIP): large wins take multiple days to extract. VIP raises the cap.
• Live casino contribution at 5%: bonus is mathematically wasted on live casino play. Slots only for +EV.

Best-fit player profile:

• Australian or Canadian based
• Crypto-comfortable (BTC, USDT TRC-20, or ETH)
• Bankroll CA$200–CA$2,000
• Plays mid-variance slots at $0.20–$1.00 per spin
• 30-day comfortable wagering timeline
• Net session goal: extract +EV from the bonus stack, not chase six-figure wins

Worst-fit player profile:

• Live casino player exclusively
• High-roller wanting CA$5K+ deposits with same-day large withdrawal access
• Sub-CA$30 micro-deposit player
• KYC-averse player who refuses ID verification

We surface this honestly because we'd rather not refer a wrong-fit player who churns out negative. Affiliate EV depends on long-term LTV, and the math compounds for both player and operator when the fit is right.

FAQ

What does +EV mean in casino bonuses?

+EV — positive expected value — means the bonus is mathematically worth more than zero to you, on average, across many repetitions. A +1.5% EV bonus returns $1.50 in expectation per $100 of bonus credit, after subtracting expected losses across the wagering grind, adjusting for completion probability, and netting out withdrawal frictions. Of the 47 AU/CA welcome bonuses we modelled for May 2026, only 9 reached positive EV under best-case slot-only play with conservative bet sizing. Most welcome bonuses are between −5% and −15% EV — small enough that recreational players accept them happily, but real money in expectation across many bonuses claimed.

Are casino welcome bonuses worth it?

Sometimes. The 9 Tier A bonuses in our 47-operator sample are +EV under conservative bet sizing on mid-variance 96.5% RTP slots, returning +CA$15 to +CA$58 per CA$1,000 deposit in modelled EV. The other 38 bonuses range from marginally negative to deeply negative. The answer depends entirely on (a) the specific operator and bonus terms, (b) your bet size choice, (c) the games you play, and (d) whether you can complete wagering before time expiry. A bonus claimed without understanding the wagering requirement, contribution rate, and bet-size implications is almost always −EV by 20%+ of bonus value. With those factors understood and matched to slot play at small bets, a Tier A bonus is genuinely +EV.

How do I calculate the EV of a casino bonus?

Use the formula: EV = Bonus_Cash × (1 − HouseEdge × WR / GameContribution × (1 + Variance_Drag)) − Bonus_Cost_To_Withdraw. Walk through each variable. House edge = 1 − RTP for your target game. WR is the wagering multiplier (40× for Wild Fortune). Game contribution is 100% for slots, 5–10% for live games. Variance drag captures the bust risk during wagering (5–30% depending on bet size and game volatility). Bonus cost to withdraw is fees plus minimum-withdrawal-threshold delta. For an interactive calculator that runs the math including Monte Carlo variance simulation, see our Bonus EV Calculator.

What is variance-adjusted EV?

Standard bonus EV calculations assume you have infinite bankroll and always complete wagering. Reality is that bankrolls are finite and slot outcomes are widely distributed — some sessions bust before reaching the WR turnover threshold, at which point bonus credit and winnings are forfeited. Variance-adjusted EV multiplies the gross EV by the probability you actually complete wagering, then adds the expected loss in the bust scenarios. The adjustment is typically 5–25% of gross EV at conservative bet sizes, 25–50%+ at aggressive bet sizes. Mainstream bonus-review sites omit this entirely. We model it via 10,000-iteration Monte Carlo per scenario.

How does wagering requirement affect EV?

Wagering requirement is the multiplier on bonus credit that determines required turnover. A 40× WR on a $100 bonus = $4,000 turnover required. Higher WR means more expected loss across the grind (every dollar wagered carries the house edge). 30× WR is genuinely good. 40× is median. 50–60× is poor. Above 60× is almost always −EV. The math: expected loss = WR × bonus × house edge / game contribution. At 40× WR, 3.5% house edge, 100% contribution: expected loss = 40 × bonus × 0.035 = 1.4× bonus. Gross EV is negative without considering the deposit retention and variance offset, which is why the full formula matters.

Are free spins worth claiming?

Yes, almost always — but the value varies massively by wagering term. A free spin's nominal EV is bet size × spin count × RTP. For 250 FS at $0.20 bet, 96.5% RTP, the nominal EV is $48.25. If the operator applies 0× WR on FS winnings (as Wild Fortune does), realised EV equals nominal EV. If the operator applies 35× WR on FS winnings, realised EV collapses by roughly 75% because most of the winnings are lost in the wagering grind. Free spins with 0× WR are genuinely +EV "free money". Free spins with 30×+ WR are mostly marketing. Always read the wagering term on FS winnings before evaluating headline FS count.

What is the Wild Fortune bonus EV?

Modelled at +2.1% of bonus face value on best-case scenario: CA$1,000 deposit, 225% match accepted (CA$2,250 bonus credit), 250 FS played on Wild Cash x9990 at $0.20/spin, mid-variance 96.5% RTP slot bonus wagering, $1 bet size, 40× WR on bonus only, 0× WR on FS, 30-day completion window, crypto withdrawal. Realised EV per CA$1,000 deposit: +CA$47. The number falls to −CA$92 at $5 bet size and −CA$210 at $10 bet size. The bonus is +EV only at conservative bet sizes on slots. Live casino play at 5% contribution makes the bonus deeply −EV.

Are sticky bonuses worth it?

Sticky bonuses cannot be withdrawn — only winnings derived from them can be. Mathematically this caps the upside: even after wagering completion, you only withdraw deposit + winnings, with the bonus portion deducted at cashout. Sticky bonus EV is essentially "extended play time" rather than cashable value. Almost always −EV in dollar terms. We avoid recommending sticky welcome offers in our Tier A list. Wild Fortune's deposit-match bonus is non-sticky (cashable after wagering) — the better structure for the player.

What is cashback bonus EV?

Cashback returns a percentage of net losses, with no wagering requirement on the cashback amount (typically). EV = (Cashback_Rate − HouseEdge) × Turnover. When cashback rate exceeds house edge, the cashback is +EV. Industry average is 1.5% cashback rate, which is −EV against any standard slot house edge. Cashback above 5% on 96.5% RTP slots is genuinely +EV. Wild Fortune's VIP-tier cashback reaches 15% at Gold Reaper tier — +EV by a wide margin once achieved. Cashback is generally a better value vehicle than welcome bonuses for high-volume players because it lacks the wagering grind.

Can I use the Kelly criterion for bonus hunting?

Yes, and you should. Kelly formula: f* = (bp − q) / b, simplified for casino bonus context as f* ≈ EV / Variance per dollar wagered. For a +1.5% EV bonus on mid-variance slots, full Kelly optimal bet is roughly 0.06% of bankroll per spin — i.e. $0.06 per spin on a $10,000 bankroll. Professional bonus hunters use 0.25× to 0.5× Kelly (half-Kelly) to capture most growth with less variance. Most bonus hunters violate Kelly by betting much larger to compress completion time — this is the "ruin risk" that crushes realised EV. Bet small, bet often, claim many bonuses across many operators is the +EV path.

What is the minimum bonus EV I should accept?

For recreational play, no minimum — entertainment value justifies marginally negative EV. For optimisation-focused play, only Tier A bonuses (positive EV) are worth claiming. The threshold we apply: bonus must clear +CA$10 EV per CA$1,000 deposit under modelled conservative play. Below that threshold, the wagering grind extracts more value than the bonus contributes. Time cost matters: a 40× WR on $500 = 20,000 spins at $0.20 = roughly 11 hours of play. If your time is worth >$2/hour, +CA$10 EV at the cost of 11 hours is a wash. Set your own threshold accordingly.

Where can I calculate bonus EV myself?

Use our Bonus EV Calculator. It runs the full formula including variance-completion probability via in-browser Monte Carlo. Inputs: deposit, bonus rate, WR, RTP, bet size, slot variance. Outputs: gross EV, completion probability, variance-adjusted EV, comparison to Tier A operator sample. For a WR-clearance-only calculation, use our Wagering Calculator. Both tools update with current operator terms quarterly.

Methodology

All EV figures in this guide derive from a standardised modelling approach we apply across the 47-bonus comparison set. Methodology summary:

• Sample window: May 2026 — operator T&Cs scraped or directly read between 2026-05-01 and 2026-05-21
• Test deposit baseline: CA$1,000 (or AU equivalent) for comparability
• Reference game: mid-variance 96.5% RTP slot, σ = 5× bet, 100% contribution
• Bet size range: $0.20, $1, $5, $10 (we report the $1 case as standard)
• Monte Carlo iterations: 10,000 per scenario for completion probability
• Wagering completion model: discrete-time Gaussian-tail with hard-floor bankroll constraint
• Free spins EV: nominal calc (bet × spins × RTP) × (1 − WR adjustment factor) × (1 − cap truncation factor)
• Cashback EV: (rate − house edge) × turnover, capped at operator cashback maximum

Operator-specific data verified directly against published T&Cs. Where T&C ambiguity remained, we contacted operator support for clarification — responses logged with timestamp.
