Casino Bonuses & Wagering Explained: A US Player's Guide
How welcome bonuses, wagering requirements, max-cashout caps and game-weighting really work — and when a bigger headline is actually worse value.

A 500% welcome bonus is only better than a 100% bonus if you actually clear the wagering before the timer runs out. At offshore casinos, the headline match percentage is the easiest number to advertise and the least useful one to compare against. The numbers that decide whether a bonus is worth claiming are the wagering multiplier, what it applies to, the game-weighting table, and the max-cashout cap sitting underneath.
This guide walks through each variable, shows why a smaller bonus with 25× wagering on the bonus-only often beats a bigger one with 50× on the bonus-plus-deposit, and covers the small print most players don't read until they've already deposited.
How wagering requirements actually work
A wagering requirement (or "playthrough") is the volume of bets you have to place before bonus winnings can be withdrawn. It's expressed as a multiplier — "35×" means you bet 35 times the bonus amount before cash-out is unlocked.
The first key distinction: is the multiplier applied to bonus only or bonus plus deposit? A $100 deposit + $100 bonus at 35× bonus-only requires $3,500 of wagering. The same 35× on bonus-plus-deposit requires $7,000. Same headline match, double the clearing work.
Game-weighting: why your table-game spins barely count
Not every bet contributes equally to wagering. Each game type has a weighting percentage that determines how much of your stake counts toward clearing. The numbers below are typical at US-facing offshore casinos — exact percentages vary per operator and are listed in the bonus terms.
- Slots: 100% — every $1 bet counts as $1 toward wagering.
- Video poker: 10–20% — every $1 counts as $0.10–$0.20.
- Blackjack and baccarat: 5–10% — every $1 counts as $0.05–$0.10.
- Roulette: 10–20% (often capped — some operators exclude red/black covering bets).
- Live dealer: Often 0% — many operators exclude live tables entirely.
If you primarily play blackjack, a slots-tilted bonus is poor value for you regardless of headline size. Check the game-weighting table before claiming any bonus.
Max-cashout caps: the quiet limit
Many bonuses include a max-cashout cap — the most you can withdraw from any winnings tied to the bonus, even after wagering is fully cleared. It's usually expressed as a multiple of the deposit (often 10× or 20×) or a flat dollar figure.
If you deposit $100 and the bonus has a 10× max-cashout, you can never withdraw more than $1,000 from that bonus session even if you genuinely won more. The excess is forfeited. This is the small print most players miss and where the operator builds in their EV.
No-wagering free spins: the cleanest bonus
A growing number of offshore operators offer no-wagering free spins as a welcome — typically 50–250 spins on a specific slot, where the winnings are credited as cash, not bonus balance. There's no playthrough to clear and no max-cashout cap (usually).
These are mathematically the cleanest bonus type for players who don't enjoy grinding through wagering. The trade-off: the headline value is lower than a 500% match — but the realized value is often higher because you actually keep what you win.
How to spot a bad bonus dressed as a good one
- Check the wagering multiplier. Above 40× on bonus-only or 25× on bonus-plus-deposit, the bonus is a grind.
- Check whether wagering applies to bonus only or bonus + deposit. The difference doubles your work.
- Check the max-cashout cap. A 500% match with a 5× max-cashout caps your winnings at 5× the deposit, period.
- Check the game-weighting table. If you don't play slots, a slot-heavy bonus undercounts your wagering.
- Check the expiry. 7 days to clear $3,500 of slot wagering is a part-time job. 30 days is realistic.
