A wager requirement is a promotional condition requiring a player to complete a stated amount of qualifying wagering before specified bonus funds, winnings, or both become withdrawable.
The term is also commonly called wagering requirement, playthrough, or rollover. The exact wording varies by operator and jurisdiction, so the formula must always be read together with the promotion’s terms.
The basic formula
If the requirement is expressed as a multiple of the bonus amount:
[ ext{Qualifying wagering target}= ext{bonus amount} imes ext{wagering multiple} ]
For a $100 bonus with a 10× requirement:
[ $100 imes10=$1{,}000 ]
The player must therefore generate $1,000 of qualifying betting volume before the specified funds become withdrawable.
That does not mean the player is expected to lose $1,000. Wagering volume and loss are different quantities.
A player can create $1,000 of wagering with much less than $1,000 of starting cash because returned winnings may be bet again. For example, $100 can circulate through many bets before the balance is either depleted or the requirement is completed. This repeated turnover is exactly why “I only deposited $100” and “I wagered $1,000” can both be true.
It also means that a wagering target does not tell you how long completion will take. Bet size, game speed, volatility, and contribution rate all affect how quickly qualifying volume accumulates and whether the bankroll survives long enough to finish.
The multiplier may apply to different bases
This is where many bonus comparisons go wrong.
One promotion may apply the multiple to the bonus only:
[ B imes m ]
Another may apply it to deposit plus bonus:
[ (D+B) imes m ]
Suppose:
- deposit (D=$100);
- bonus (B=$100);
- multiple (m=10).
Bonus-only calculation:
[ $100 imes10=$1{,}000 ]
Deposit-plus-bonus calculation:
[ ($100+$100) imes10=$2{,}000 ]
Both offers can be described casually as “10× wagering,” yet one requires twice as much qualifying action. The base of the multiplier matters as much as the multiplier itself.
Qualifying wagering is not always the same as actual wagering
Many promotions use game weighting. A $1 bet may count as:
- $1.00 of progress on one game;
- $0.20 on another;
- $0.00 on an excluded game.
If a game contributes at rate (c), then the actual betting needed to produce a remaining qualifying target (Q) is:
[ ext{Actual wagering needed}= rac{Q}{c} ]
If $1,000 of qualifying progress remains and blackjack contributes 10%:
[
rac{$1{,}000}{0.10}=$10{,}000 ]
of actual blackjack wagering would be needed, assuming the terms permit it and the contribution rate stays constant.
This is why a low house edge does not automatically make a promotion cheap to clear.
Wager requirement and expected loss are different concepts
A wager requirement tells you how much action must occur. Expected loss estimates the average mathematical cost of that action.
A simplified estimate is:
[ ext{Expected loss}= ext{actual wagering} imes ext{house edge} ]
If clearing a promotion requires $2,000 of actual wagering on a game with a 4% house edge:
[ $2{,}000 imes0.04=$80 ]
The expected game loss is $80.
That does not mean every player will lose $80. Variance can produce a large win, an early wipeout, or anything in between. It is an average-cost calculation, not a session forecast.
Why Casino Bonuses Are Not the Same as Free Cash applies this distinction to the value of the whole offer.
Maximum-bet rules can matter as much as the multiple
Some promotions restrict the maximum permitted stake while bonus funds are active.
That prevents a player from trying to clear the requirement with a few extremely large wagers. Breaking the maximum-bet rule may affect promotional eligibility or winnings depending on the terms and applicable regulation.
The useful lesson is simple: clearing faster is not automatically allowed.
A player must read the maximum stake, excluded games, expiry time, and withdrawal conditions before calculating whether the requirement is realistic.
Expiry is especially easy to overlook. A mathematically attractive offer can become impractical if the qualifying volume must be completed within a short period that encourages larger stakes or longer sessions than the player would otherwise choose. The time limit therefore belongs in the economic calculation: a bonus that is only valuable under a pace you do not want to maintain may not be valuable to you at all.
“Cashable,” “sticky,” and similar labels are not universal legal categories
Casino sites and players often use shorthand labels for different bonus structures. For example, a promotion may allow the bonus itself to become withdrawable after completion, while another may permit withdrawal of winnings but remove the original promotional credit.
Those labels are not a substitute for the actual terms.
The precise questions are:
- What money becomes withdrawable after completion?
- What happens to bonus funds when a withdrawal is requested?
- Are winnings capped?
- Does the promotion expire?
- Are deposits and bonus funds kept in separate balances?
Two offers with the same wagering multiple can have very different economic value because these rules differ.
Current Great Britain rules provide a useful jurisdiction example
Since 19 January 2026, Great Britain-licensed operators may not apply wagering requirements above 10 times the incentive amount. The rule defines a wagering requirement as a condition requiring a customer to make wagers totalling a particular value for funds to become withdrawable.
That 10× limit is not a global definition of a good bonus and does not apply automatically outside Great Britain. It is a jurisdiction-specific regulatory cap. The current wording is set out in the Gambling Commission’s incentive rules.
The existence of a regulatory cap is also a reminder that wagering requirements affect both transparency and gambling exposure; they are not merely a technical line in promotional fine print.
Do not confuse wagering with deposits
Wagering is the amount staked repeatedly through bets. It can be far larger than the money originally deposited.
A player might deposit $200 and generate $5,000 of total wagers because wins are repeatedly re-bet. A wagering requirement is measured against this action, subject to the promotion’s contribution rules.
That is why “I only deposited $200” does not tell you how much gambling occurred.
A practical way to compare two offers
For each bonus, write down:
| Variable | What to record |
|---|---|
| Bonus amount | Promotional credit received |
| Requirement base | Bonus only, deposit + bonus, or another stated base |
| Multiple | 5×, 10×, etc. |
| Contribution rate | How much each game counts |
| Actual wagering needed | Qualifying target divided by contribution rate |
| Effective house edge | Cost of the permitted strategy/game |
| Expiry | Time available to complete |
| Max bet | Largest permitted stake while active |
| Withdrawal rule | What becomes cashable after completion |
Then estimate:
[ ext{Expected clearing cost}pprox ext{actual wagering needed} imes ext{effective house edge} ]
This is still only part of the valuation because variance and withdrawal restrictions matter, but it is far more informative than comparing bonus percentages alone.
A wager requirement is therefore best understood as an action threshold. It tells you how much qualifying betting must occur before specified promotional value becomes withdrawable. It should be evaluated together with the bankroll needed to survive the required action, not as a percentage printed in isolation. It does not tell you how much you will lose, whether you will finish the requirement, or whether the offer is worthwhile by itself.
