RTP (Return to Player) is one of the most important numbers in online gambling. It tells you, as a percentage, how much of all money wagered on a game is paid back to players over time. A slot with 96% RTP returns $96 for every $100 bet — the casino keeps $4.
How RTP Is Calculated
RTP is calculated over millions of spins by game developers and certified by independent testing labs (eCOGRA, GLI, iTech Labs). It is a long-term statistical average, not a guarantee for any single session.
RTP by Game Type
| Game | Typical RTP | Notes |
|---|---|---|
| Blackjack (basic strategy) | 99.5% | Requires correct play |
| Baccarat (Banker) | 98.9% | Best casino bet |
| European Roulette | 97.3% | Single zero |
| Slots (average) | 94%–97% | Varies by title |
| American Roulette | 94.7% | Avoid — double zero |
| Crash games | 95%–99% | Depends on casino |
| Keno | 65%–80% | Worst RTP games |
RTP vs House Edge
RTP and house edge are two sides of the same coin: House Edge = 100% − RTP. A 96% RTP slot has a 4% house edge — meaning the casino earns $4 on every $100 wagered on average.
RTP vs Volatility
A high RTP does not mean you will win frequently. Volatility (variance) determines payout frequency:
- Low volatility: Frequent small wins. Best for wagering requirements.
- High volatility: Rare but large wins. Need a bigger bankroll.
- High RTP + high volatility: Long dry streaks possible despite good long-term odds.
Where to Find a Game's RTP
Most providers display RTP in the game info panel (tap the "i" or "?" icon). In crypto casinos, games with provably fair mechanics often let you verify RTP on-chain. If RTP isn't listed, check the provider's official website or game review sites.

RTP in Bonus Wagering
During bonus wagering, choose the highest-RTP slot you can find. If you need to bet $3,000 to clear a bonus: at 96% RTP you lose $120 on average; at 99% RTP you lose only $30. The difference is significant.
