To use a deposit bonus on crash games, check that crash counts towards wagering, claim the bonus, then clear it with flat bets and a low auto cash out such as 1.2x–1.5x. A 100% bonus turns a £50 deposit into £100 to play with. The price is the wagering requirement: at 30x the bonus that’s £1,500 in bets, which costs about £45 on average at a 97% RTP, or £15 on a 99% RTP crash original. Get those numbers right and a bonus is one of the best deals in crash gaming. Part of our crash game strategy guide.
A full worked example
Illustrative terms: 100% bonus, 30x wagering on the bonus, crash counts at 100%, max bet £5.
| Step | Amount |
|---|---|
| Deposit | £50 |
| Bonus | £50 |
| Starting balance | £100 |
| Wagering needed (30 × £50) | £1,500 |
| Rounds at £5 | 300 |
| Expected cost at 97% / 99% RTP | £45 / £15 |
On average you’d finish wagering with about £55 at 97% RTP or £85 at 99%, from a £50 deposit. Real sessions swing around that, so the target matters.
The best target for bonus play
Our simulation of exactly this example (10,000 runs, £5 flat bets):
| Auto cash out | Ran dry at 97% RTP | Ran dry at 99% RTP |
|---|---|---|
| 1.2x | 16.1% | 4.2% |
| 1.5x | 31.0% | 16.8% |
| 2x | 42.4% | 30.6% |
Lower targets finish the wagering far more often. Full breakdown in wagering requirements and crash games and the 1.2x strategy.
Bonus mistakes to avoid
- Betting above the max bet. It can void the bonus.
- Chasing with progressions. The Martingale strategy raises bets when your balance is weakest.
- Ignoring contribution rates. If crash counts at 50%, double the wagering.

Where to use it
Compare bonus offers at the casino you play with, and if cash back suits you better, read how rakeback works for crash. Test your bonus plan in the simulator below, then play it in Aviator.
Pro tip: do the cost maths before you claim: wagering × house edge. If the bonus is bigger, you’re in a good spot.

8.3Frequently asked questions
Can I use a deposit bonus on crash games?
Often, yes, but check the terms: some casinos count crash games fully towards wagering, some partly and some not at all.
How does a 100% deposit bonus work?
The casino matches your deposit. Deposit £50, get £50 bonus, and play with £100. You usually need to meet a wagering requirement before withdrawing bonus winnings.
What’s the best crash strategy with a bonus?
Flat bets with a low auto cash out (1.2x–1.5x), within the bonus max-bet rule, until the wagering is done.
Is a deposit bonus worth it for crash players?
When crash counts at 100% and the bonus is worth more than the expected wagering cost, it’s a strong deal on average.
What happens if I bust before finishing wagering?
The bonus is gone, along with the deposit you played it with. Low targets and flat stakes make that less likely.
