A wagering requirement is the amount a player must bet before bonus funds, free-spin winnings, or promotional credits can usually be withdrawn. It is also called playthrough or rollover. The term matters because a bonus that looks large can become expensive once the required betting is counted.
Plain Talk
A wagering requirement is the casino saying, “You cannot just take this bonus and leave. You must play a certain amount first.” If a $20 bonus has a 30x wagering requirement, the player may need to wager $600 before the bonus-related money becomes withdrawable.

| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Wagering requirement | Required betting before withdrawal | Online bonuses and free spins | Turns bonus size into real cost |
| Playthrough | Another name for wagering requirement | Bonus terms | Same basic idea |
| Rollover | Sportsbook-style name for playthrough | Promotions | Often used outside casino slots |
| Eligible games | Games that count toward the requirement | Bonus rules | Some games count less or not at all |
Where You See It
You see wagering requirements in online casino bonus terms, free-spin offers, deposit matches, cashback promotions, and sometimes social-casino or sweepstakes-style rules. The UK Gambling Commission glossary treats bonuses and free spins as consumer-facing promotional terms, while its fair terms guidance explains why unclear conditions can be a regulatory concern. Advertising guidance such as the ASA guidance for free bets and bonuses also focuses on how key conditions should be shown to consumers.
Why It Matters
Wagering requirements matter because they change the real value of a promotion. A $100 bonus is not automatically worth $100. If the player must wager thousands to unlock it, the house edge on those wagers can eat the value before the player ever withdraws.
This is also a responsible gambling term. A player can end up gambling longer than planned because the bonus still has “more to clear.” If this term describes something happening to you, the smart move is not a better system. It is a pause.
Example
A casino offers a $50 bonus with a 20x wagering requirement on the bonus amount. The required wagering is:
$50 × 20 = $1,000
If only selected slots count, the player must wager $1,000 on eligible games before the bonus winnings can normally be withdrawn. If those slots have a house edge, the bonus is not free money; it is discounted play with conditions.
From the Casino Side:
From the casino side, a wagering requirement protects promotional cost. Marketing wants the bonus to attract sign-ups and repeat visits. Finance wants the offer controlled. Compliance wants the terms displayed clearly. Risk teams watch for abuse, duplicate accounts, and play patterns that violate terms.
A wagering requirement is not only a player rule. It is a business control.
Common Misunderstanding
The common mistake is looking only at the bonus amount. Players see “$100 bonus” and ignore the required turnover, max bet, game contribution, expiration date, and withdrawal cap.
Hard Truth
The bonus number is the bait. The wagering requirement is the bill.

FAQ
Is a wagering requirement the same as playthrough?
Yes. In casino bonus language, playthrough usually means the same thing: the amount you must wager before bonus-related funds can be withdrawn.
Is a low wagering requirement always good?
Lower is usually better than higher, but the full terms still matter. Eligible games, maximum bet, withdrawal caps, expiry dates, and excluded strategies can change the value.
Do all games count the same toward wagering requirements?
No. Slots may count 100%, while table games, video poker, or live dealer games may count less or be excluded. Always read the offer terms.
Can wagering requirements make a bonus negative value?
Yes. If the required betting creates more expected loss than the bonus is worth, the offer is not mathematically attractive.
Why do casinos use wagering requirements?
They stop players from claiming a bonus and instantly cashing out. They also encourage more play, which creates expected revenue for the casino.

Formula / Calculation
| Metric | Formula | Plain-English meaning |
|---|---|---|
| Required Wagering | Bonus Amount × Wagering Multiplier | How much must be bet before withdrawal |
| Expected Loss on Playthrough | Required Wagering × House Edge | The average cost of clearing the bonus |
| Rough Bonus Value | Bonus Amount - Expected Loss | A simple estimate before restrictions |
Example:
Required Wagering = $50 × 20 = $1,000
Expected Loss = $1,000 × 5% = $50
In that simplified example, a $50 bonus played through a 5% house-edge game with 20x playthrough may be roughly break-even before max-bet rules, game restrictions, variance, and withdrawal caps.
Formula Explanation in Plain English
The wagering multiplier tells you how much action the casino wants before money becomes withdrawable. The house edge on that action is the hidden cost. The bonus only has real value if the expected cost of clearing it is lower than the usable bonus amount.
