Casino bonuses can be genuinely valuable — or a trap that locks up your money — and the difference almost always comes down to wagering requirements. Understanding how playthrough rules work is the key to knowing which offers are worth claiming and which ones to skip. This guide breaks down wagering requirements in plain English so you can play smarter.
Quick answer: A wagering requirement is the number of times you must bet a bonus (and sometimes your deposit) before you can withdraw winnings. A "20x" requirement on a $100 bonus means you must wager $2,000 first. Lower multipliers, generous game weighting, and longer time limits make a bonus more valuable.
What Are Wagering Requirements?
When an online casino offers a bonus, it attaches conditions to prevent players from instantly cashing out free money. The wagering requirement — also called playthrough or rollover — specifies how much you must bet before bonus funds convert to withdrawable cash. It is expressed as a multiplier, such as 20x or 35x.

How the Math Works
Suppose you claim a $100 bonus with a 25x wagering requirement. You must place $2,500 in total bets (25 × $100) before withdrawing any bonus-derived winnings. Some casinos apply the multiplier to the bonus plus the deposit. If your $100 deposit and $100 bonus both count at 25x, you would need to wager $5,000. Always read whether the requirement applies to "bonus" or "deposit + bonus" — it dramatically changes the value.
Game Weighting Matters
Not every game contributes equally toward clearing a bonus. Typical weighting looks like this:
- Slots: Usually count 100% — every $1 wagered reduces the requirement by $1.
- Blackjack and video poker: Often count 10% or less, because their low house edge favors players.
- Roulette and baccarat: Frequently weighted at 10–25% or excluded entirely.
- Live dealer games: Vary widely; check the terms before playing.
This weighting explains why most bonuses are effectively slots offers. If you prefer table games, factor the reduced contribution into your decision. Our live dealer casinos guide notes how different operators treat these games in bonus terms.
Other Terms to Check
- Time limits: Many bonuses expire in 7–30 days; tight windows make high requirements hard to clear.
- Maximum bet caps: Exceeding a per-spin or per-hand cap can void your bonus.
- Game restrictions: Some titles are excluded from bonus play entirely.
- Maximum cashout: No-deposit bonuses often cap how much you can withdraw.
How to Evaluate a Bonus
Before claiming any offer, run through this checklist:
- Identify the multiplier: Lower is better. Under 30x is generally favorable.
- Confirm what it applies to: Bonus only, or deposit plus bonus?
- Check game weighting: Match it to the games you actually want to play.
- Read the time limit: Make sure it is realistic for your playing volume.
- Note bet caps and excluded games: Avoid accidentally voiding the offer.

Common Bonus Mistakes
- Chasing huge headline numbers: A 300% bonus with 50x playthrough can be worse than a 100% bonus at 20x.
- Ignoring game weighting: Grinding blackjack at 10% contribution rarely clears a bonus efficiently.
- Missing the time limit: Unfinished requirements mean forfeited bonus winnings.
- Betting above the cap: One oversized wager can void everything.
Calculating a Bonus's Real Value
To compare offers objectively, it helps to estimate a bonus's expected value rather than reacting to the headline percentage. The rough formula multiplies the bonus amount by the chance you clear it and subtracts the expected losses you will incur while wagering. The two biggest drivers are the wagering requirement and the house edge of the games you play to clear it. A lower multiplier on a low-edge game preserves far more of the bonus than a huge multiplier on a high-edge slot.
Consider a simple example. A $100 bonus at 25x requires $2,500 in wagers. If you clear it on slots with a 4% house edge, your expected cost in losses is roughly $100 (4% of $2,500) — meaning the bonus, on average, roughly breaks even before any variance. Now compare a $100 bonus at 10x: you only wager $1,000, expecting about $40 in losses, leaving meaningfully more bonus value intact. This is why experienced players hunt for low-rollover offers even when the headline amount is smaller.
The takeaway is that the multiplier and game weighting matter far more than the bonus size that operators advertise in bold. Before depositing, do the quick math: total wagering required, the house edge of your chosen game, and whether the time limit is realistic for your volume. A bonus is only worth claiming when those numbers work in your favor — and learning to run that calculation in seconds is one of the most profitable habits a casino player can develop.
Frequently Asked Questions
What does a 20x wagering requirement mean?
It means you must wager 20 times the bonus amount before withdrawing winnings. A $100 bonus at 20x requires $2,000 in total bets.
Do all games count toward wagering requirements?
No. Slots usually count 100%, while table games like blackjack and roulette often count 10% or less, or are excluded entirely.
Are casino bonuses worth it?
They can be, if the wagering requirement is low, the game weighting suits your style, and the time limit is realistic. Always read the terms first.
What is the difference between bonus and deposit-plus-bonus rollover?
Bonus-only rollover applies the multiplier to the bonus amount; deposit-plus-bonus applies it to both, effectively doubling the wagering needed.
