Wagering requirements are the most important — and most misunderstood — part of any casino bonus. A $1,000 welcome bonus with 40× wagering is worth far less than a $200 bonus with 1× wagering. In this guide, our expert analysts break down exactly how wagering works, how to calculate the real value of any bonus, and which US casinos offer the most player-friendly terms.
What Are Wagering Requirements?
A wagering requirement (also called a playthrough requirement or rollover) specifies how many times you must bet the bonus amount — and sometimes your deposit as well — before any winnings become withdrawable.
For example: You claim a $100 bonus with 20× wagering. You must place $2,000 in total bets before you can cash out. If the requirement is on bonus + deposit, and you deposited $100 to get the $100 bonus, you'd need to wager $4,000.
Always check whether wagering applies to:
- The bonus only
- The bonus + deposit
How to Calculate Real Bonus Value
The real value of a bonus is determined by: (Bonus Amount) ÷ (Wagering Requirement × 2) × House Edge Rate
In practice, assume roughly 50–60% of each wager is returned as winnings when meeting wagering on slots (which typically count 100%). This means:
- $100 bonus at 20× wagering = $2,000 total bets needed → approximately $40–50 of real expected value
- $200 bonus at 1× wagering = $200 total bets needed → approximately $190–195 of real expected value
This is why FanDuel's "Play $1, Get $200" offer with 1× wagering is fundamentally more valuable than a $1,000 bonus at 40× wagering.
Game Contribution Rates
Not all games contribute equally to wagering requirements. Here are typical contribution rates:
- Slots: 100% (most common)
- Blackjack: 5–20% (often excluded entirely)
- Roulette: 5–20%
- Live dealer games: 0–25%
- Video poker: 0–20%
This is why casinos with table game restrictions should be evaluated carefully if you prefer non-slot games.
Red Flags to Watch For
Watch out for these bonus term red flags:
- Maximum win cap: Many bonuses cap winnings from bonus funds at $200–500, regardless of how much you win
- Bonus expiry: If you don't meet wagering within 30 days (or sometimes 7 days), the bonus and any winnings are forfeited
- Game restrictions: Some bonuses exclude specific high-RTP games
- Maximum bet while wagering: Typically $5 per spin/hand — exceeding this can void the bonus

Conclusion
Wagering requirements are not a reason to avoid casino bonuses — they're a reason to choose bonuses more carefully. A 1× wagering offer is almost always better than a 40× offer, even with a much smaller headline number.
