Why wagering requirements exist

Give a player 100 in free money with no conditions and the rational response is to withdraw 100. No play, no revenue, no reason for the casino to have offered it.

The requirement forces turnover, and turnover is where the edge operates.

Expected cost of clearing = Bonus × Multiple × House edge

A 100 bonus at 30x on a 4% edge game:

100 × 30 × 0.04 = 120

The expected cost of clearing exceeds the bonus. On average, the operator recovers the full 100 and 20 more before the requirement is met.

That's the design. The bonus isn't a gift with a condition attached — the condition is calibrated so the gift has negative expected value, and the operator is buying the play, not giving away the money.

→House edge, explained with real numbers covers the mechanism doing the recovering.

The number is meaningless without knowing what it multiplies. Two conventions:

Bonus only. 30x on a 100 bonus = 3,000 turnover.

Deposit + bonus. 30x on a 100 deposit matched with a 100 bonus = 30 × 200 = 6,000 turnover.

Same "30x". Double the work.

Always find which convention applies before comparing two offers. A 25x deposit+bonus requirement is worse than a 40x bonus-only one.

Run the arithmetic on any offer rather than judging the multiple alone. At a 4% edge, break-even is around 25x on bonus-only — above that, you're expected to lose more clearing it than the bonus is worth.

Note this cuts the other way on low-edge games, which is exactly why they're weighted down.

Contribution rates apply to playthrough as well as cashback, and for the same reason.

Blackjack at 10% contribution against a 3,000 requirement means 30,000 of actual blackjack turnover.

The logic is direct: blackjack's 0.5% edge recovers a bonus far too slowly. Weighting it down forces the requirement onto games where the edge does the job at the intended pace. Low-edge games are cheap to play and therefore useless to the operator for clearing bonuses.

Some operators additionally exclude specific high-RTP slot titles outright.

Maximum bet while wagering. Commonly capped around 5 per spin. Exceeding it is grounds for voiding the bonus and everything won from it, and it's enforced automatically. This is the most frequent cause of forfeited winnings in the entire category.

Time limit. Typically 7 to 30 days. Unmet requirements expire and take the bonus and associated winnings with them.

Maximum conversion. A cap on how much bonus-derived winnings can be withdrawn — often 5x or 10x the bonus, sometimes a flat figure. You can clear the requirement and still forfeit the surplus above the cap.

Sticky vs non-sticky. A sticky bonus can't be withdrawn at all; only winnings above it can. A non-sticky bonus becomes cash on clearing. Materially different products with identical marketing.

Any of these four can matter more than the headline multiple. The maximum bet clause in particular voids more balances than high multiples ever cost anyone.

This is the structural distinction worth carrying away.

A bonus is money you didn't have. A rebate is a partial return of money you already staked. The operator isn't exposed to a player claiming and immediately withdrawing, because the rebate only exists as a consequence of turnover that already happened.

So wager cashback generally arrives as withdrawable balance with no playthrough. Nothing needs protecting against.

Deposit and milestone cashback are different. Deposit cashback is triggered by depositing rather than playing, which reintroduces the deposit-and-withdraw problem — so it frequently carries a requirement. Milestone cashback sometimes does.

When comparing a cashback offer against a bonus, this is usually the largest difference between them, and it's rarely reflected in how they're advertised.
