Wagering Requirement

A wagering requirement is the amount of qualifying gambling activity that must be completed before bonus funds, or winnings connected with those bonus funds, become withdrawable. It is also called playthrough or rollover.

The multiplier is only one part of the rule. A promotion saying “10x wagering” is impossible to value correctly until you know 10 times what, which games count, how quickly they count, and what restrictions apply while the requirement is active.

“10x” can mean three very different obligations

Suppose a player deposits $50 and receives a $50 bonus. Three promotions could all display a 10x multiplier while requiring different turnover:

The general formula is:

where:

• Q = required qualifying turnover;
• B = the bonus base named in the terms;
• M = the wagering multiplier.

The formula measures the workload of the requirement. It does not yet measure the expected cost of completing it.

Game weighting can make the real turnover much larger

Promotions often specify that different games contribute different percentages toward the requirement. A slot may contribute 100%, while blackjack or roulette may contribute 20%, 10%, or nothing at all. There is no universal contribution table; the promotion's own terms control.

If a game contributes less than 100%, actual wagering required is:

where A is actual betting required and c is the contribution rate written as a decimal.

Suppose $500 of qualifying turnover remains:

This is why a seemingly low multiplier can still create heavy play. The advertised number may describe qualifying turnover while the contribution schedule determines how much money must actually be wagered.

The bonus has an expected cost before variance arrives

Once actual wagering is known, expected gambling cost can be estimated:

where e is the house edge of the game being used under the relevant rules and strategy assumptions.

Imagine a $50 bonus with a $500 qualifying requirement. The player chooses an eligible slot with 96% theoretical RTP, corresponding to a 4% theoretical house edge, and that game contributes 100%.

The rough expected playthrough cost is $20. Ignoring all other restrictions, a crude expected-value starting point would be:

That $30 is not cash waiting to be collected. It is an expectation before variance, maximum-bet rules, expiry, cash-out caps, game exclusions, balance-order rules, or the possibility of losing the playable balance before the turnover is completed.

A player can therefore receive a promotion with positive rough mathematical value and still finish with nothing. Conversely, a player can complete an unattractive promotion and happen to finish with a large balance. Expected value evaluates the offer over repeated comparable situations; it does not guarantee the result of one redemption.

The survival problem is different from the average cost

Expected loss alone can make a promotion look easier than it is. A $20 expected cost on $500 of slot action sounds modest, but the player must still survive the volatility of the game long enough to generate $500 of qualifying wagers.

Suppose two eligible games both have 96% RTP. One is relatively low volatility and the other concentrates more return into infrequent large wins. Their theoretical expected loss per $500 of action is the same $20, but the probability of the balance reaching zero before completion can be different.

That is one reason wagering requirements are not evaluated properly by RTP alone. The available balance, bet size, volatility, contribution rate, and remaining turnover interact. A promotion can have reasonable theoretical value but poor practical survivability if the permitted bankroll is small relative to the required action.

Maximum-bet rules can void an otherwise good calculation

Many bonus terms impose a maximum stake while promotional funds are active. The purpose from the operator's side is often to prevent a player from taking a small number of very large, high-variance shots and then grinding the remaining requirement at small stakes.

For the player, the operational lesson is simple: a mathematically sensible strategy can still breach the contract if the stake exceeds the stated maximum. The fact that the software accepted the wager does not always mean the terms permitted it.

Before playing, identify whether the cap applies per spin, per hand, per betting round, or to total wagers placed simultaneously. Also check whether different limits apply to cash play and bonus play.

Withdrawable cash and bonus money should not be treated as one balance

Online interfaces may show one headline balance even when the underlying account distinguishes deposited cash, bonus credit, free-spin winnings, restricted winnings, and withdrawable funds. The order in which those balances are consumed can materially change the offer.

Questions worth answering before accepting a bonus include:

• Does cash or bonus credit get wagered first?
• Can the player cancel the bonus and withdraw remaining cash?
• What happens to bonus-derived winnings if the promotion is cancelled?
• Are open wagers settled before a withdrawal or cancellation?
• Does a withdrawal request forfeit the bonus automatically?

Those are contractual questions, not casino-math questions. If the terms are unclear, the safest calculation is not to assume the most favorable interpretation.

Great Britain now caps covered bonus wagering requirements at 10x

Jurisdictions regulate promotions differently. A current example is Great Britain. Since 19 January 2026, the UK Gambling Commission's Social Responsibility Code 5.1.1 prohibits covered licensees from applying wagering requirements to incentives that require customers to play through bonus funds at more than 10 times. The rule defines a wagering requirement as requiring wagers totaling a particular value before funds become withdrawable.

The current UK Gambling Commission Rewards and Bonuses code also prohibits combining more than one gambling product type within an incentive. The Commission has separately emphasized that restrictions on bonus winnings do not give operators a general right to lock a customer's own deposit winnings indefinitely.

That 10x rule is jurisdiction-specific. It should not be copied onto an offer governed by another country's law, a U.S. state regime, a tribal gaming framework, or an unlicensed website. For any current promotion, first identify the operator's licence and the rules that actually apply to it.

Headline bonus size is a poor comparison tool

Consider two promotions played on the same 96% RTP slot, assuming 100% contribution and ignoring variance and other restrictions.

Offer B advertises the larger bonus but creates three times as much wagering and twice the expected playthrough cost relative to the bonus. If Offer B also has a low maximum cash-out or short expiry, the comparison can become even worse.

This does not prove Offer A is always superior. It shows why the headline bonus amount is an incomplete metric.

Expiry turns a math problem into a time-pressure problem

A requirement can be mathematically clear and still be impractical. If $5,000 of actual betting must be completed within 24 hours, the deadline may push the player toward more hands, faster play, larger stakes, or longer sessions than originally intended.

The deadline does not improve expected value. It changes the behavior required to reach the theoretical value before the offer expires.

That is particularly important when a promotion is accepted casually because the bonus looked “free.” A bonus that pressures a player to gamble when they otherwise would have stopped is not free in any useful economic sense.

A seven-line check before accepting a bonus

Write down these figures and rules before opting in:

1. Bonus amount: how much promotional value is actually usable?
2. Multiplier: what is the stated wagering multiple?
3. Multiplier base: bonus only, deposit plus bonus, winnings, or something else?
4. Game contribution: what percentage of each wager counts?
5. Maximum stake: what betting size is permitted while the bonus is active?
6. Expiry and cash-out: when does the offer expire and is withdrawable value capped?
7. Balance treatment: which funds are used first and what happens if the bonus is cancelled?

Then calculate qualifying turnover, convert it to actual wagering using the contribution rate, and estimate expected playthrough loss using the chosen game's edge. The expected value concept helps compare the promotional value with its mathematical cost, while expected loss explains what the required action costs on average.

A wagering requirement is therefore best understood as a conversion condition: it sets the amount and type of gambling activity required before promotional value can become withdrawable. The multiplier matters, but the real value of the offer depends on the base, contribution rules, game price, variance, limits, deadline, and withdrawal terms surrounding it.
