Bonus wagering requirements are the single most important number on any casino offer and one of the most-misunderstood ones. The headline reading — 'I have to spend $3,000 to clear a $100 bonus' — is wrong in a way that matters: you don't have to spend $3,000, you have to wager $3,000. Those are different numbers and the difference determines whether the bonus is worth your time.
Wager vs. cost
Wagering counts the cumulative amount staked across spins, not the cumulative net loss. If you start with a $100 bonus and play $1 spins on a 96% RTP slot, the expected cost per spin is $0.04 (the four-percent edge). Across $3,000 of total wagering, the expected cost is $120 — which is more than the bonus amount, meaning the bonus has negative expected value at 30x wagering.
The general formula: expected cost to clear = wagering requirement × (1 − RTP). At 30x wagering on a $100 bonus with 96% RTP slots, that's $3,000 × 0.04 = $120 of expected cost. The bonus is worth $100. Net expected value: minus $20.
The wagering tiers that matter
- 1x–10x: bonus has clearly positive expected value. At 5x wagering on a $100 bonus with 96% RTP slots, expected cost is $20 and the bonus is worth $100 — net plus $80.
- 20x–30x: industry standard. Expected value is near zero or slightly negative depending on the exact RTP of the games you play.
- 40x+: bonus is marketing-only. Expected value is clearly negative; the operator is using the bonus to anchor your deposit, not to give you money.
- 50x+ on bonus-plus-deposit: doubly negative. The wagering applies to the combined balance, doubling the cost-to-clear math.
Game contribution rules
Slots typically count at 100% toward wagering. Table games (blackjack, roulette, baccarat) count at 5% to 20%. Live dealer counts at 10% or sometimes 0%. Originals count at 10% to 50%, with provably-fair games often at the lower end. The contribution rules are how the operator forces you to play higher-edge games to clear the bonus.
Math example: $3,000 of wagering required, blackjack contributes at 10%. To clear via blackjack only, you'd need to wager $30,000. At a half-percent house edge, that's $150 of expected cost — meaningfully worse than the slot route's $120 despite blackjack's lower edge.
Max bet caps during clearing
Most bonus terms include a maximum bet cap during the wagering period — usually $5, sometimes $1 or as low as 50 cents. The cap is enforced; bets above the cap can void the bonus entirely if the operator's system catches it. The cap exists because high single-bet wagering produces variance that lets players occasionally clear the bonus on a streak, which the operator doesn't want to subsidize.
Max cashout caps
On no-deposit and free-spin offers, the operator typically caps the amount you can withdraw from bonus-derived winnings, often at $50 to $200. That's the second checkpoint after wagering, and it's often the more binding one — a no-deposit $25 bonus with $50 max cashout is worth at most $50 net of clearing costs.
Quick rule of thumb: bonus expected value ≈ bonus amount − (wagering × 4%). At 25x wagering on a $100 bonus, that's $100 − $100 = $0 expected value. Anything tighter than 25x is positive; anything looser is negative.
