Every casino bonus lives or dies by one number: the wagering requirement (also called playthrough or rollover). It's the mechanism that stops "free money" from being withdrawn immediately — and it's where casinos hide the real cost of a generous-looking headline.
The Basic Mechanics
"$100 bonus, 35x wagering" means you must place $3,500 in total bets before the bonus (and winnings from it) become withdrawable. Three things people get wrong:
- It's cumulative turnover, not losses. Win or lose each spin, the amount you bet counts. You could clear $3,500 in wagering while ending up ahead.
- The base matters enormously. "35x bonus" on $100 = $3,500. "35x deposit + bonus" on a $100 deposit = $7,000. Same multiplier, double the requirement.
- Your cash is often locked too. At many casinos, accepting a bonus locks your deposit until wagering completes. This is the hidden cost casual players miss.
What Clearing Actually Costs
Because every bet passes through the house edge, wagering has a predictable expected cost:
Expected cost = Total wagering × House edge
$100 bonus at 35x = $3,500 turnover.
On a 96% RTP slot (4% edge): $3,500 × 0.04 = $140 expected loss — more than the bonus.
On a 97.5% RTP slot (2.5% edge): $3,500 × 0.025 = $87.50 expected loss — the bonus retains ~$12 of value.
The same bonus is good or bad purely depending on what you play and the multiplier.
This is why our RTP guide is the natural companion to this one: bonus clearing on high-RTP games can be nearly break-even, while the same bonus cleared on low-RTP games is guaranteed value destruction.
Game Weightings: The Multiplier Behind the Multiplier
| Game Type | Typical Contribution | Effective Requirement (35x) |
|---|---|---|
| Slots | 100% | 35x |
| Scratch cards / keno | 100% | 35x |
| Roulette | 10–20% | 175–350x |
| Blackjack / baccarat | 5–10% | 350–700x |
| Live dealer games | 0–10% | Often excluded |
The pattern is deliberate: games where skill reduces the house edge contribute least. If you're a table game player, most deposit bonuses simply aren't for you — play cash instead, or choose casinos with rakeback structures that reward every game equally.
The Rules That Void Bonuses
- Max bet rule Usually $5 per spin/hand while wagering is active. One $10 spin — even by accident — can void the bonus and all winnings. This is the most common confiscation trigger in complaint records.
- Restricted games Betting on excluded games during wagering (often jackpot slots and some high-RTP titles) can void everything.
- Low-risk betting patterns Covering most of a roulette table, or betting red and black simultaneously, is classed as bonus abuse at virtually every casino.
- Time expiry Wagering not completed in the window (7–90 days) forfeits the bonus and its winnings. Cash balances are unaffected.
When to Refuse a Bonus
- You mainly play table games or live dealer — the weightings make clearing impractical
- The requirement is above 50x, or applies to deposit + bonus
- There's a win cap below 5x the bonus
- You want the option to withdraw on short notice — locked balances and wagering don't mix with flexible play
Wager-free alternatives exist: Stake's rakeback attaches zero requirements to its rewards, and several licensed casinos now offer wager-free spins. Our bonus comparison flags which offers are wager-free.
