RTP (Return to Player) is the percentage of wagered money a casino game returns to players over millions of plays. A 96% RTP slot returns $96 for every $100 bet on average long-term. This metric, set by game developers and verified by independent auditors in regulated markets like Ontario, informs player choices on expected value without implying short-term wins.
How RTP Works in Casino Games
RTP is the inverse of house edge: 96% RTP equals 4% house edge. Video slots typically range 94-98%, blackjack 99%+ with optimal play, roulette 97.3% on European wheels. Figures represent theoretical averages over infinite trials, certified by labs like eCOGRA or iTech Labs for fairness in Canada-licensed sites.
| Game Type | Typical RTP Range | House Edge |
|---|---|---|
| Video Slots | 94-98% | 2-6% |
| Blackjack | 99-99.5% | 0.5-1% |
| European Roulette | 97.3% | 2.7% |
| Video Poker | 98-99% | 1-2% |
