RTP & House Edge Explained
What is RTP (Return to Player)?
RTP stands for Return to Player — the percentage of all wagered money that a game is statistically expected to pay back to players over a large number of rounds. For example, a slot with 96% RTP will, on average, return ৳96 for every ৳100 wagered across all players combined. RTP is a long-run statistical average, not a guarantee for any individual session.
What is House Edge?
House edge is the mathematical advantage a casino holds over players, expressed as a percentage. It is the inverse of RTP: if a game has 97% RTP, the house edge is 3%. Understanding house edge helps you choose games where your money lasts longer and your chances of a winning session are higher. Games like blackjack and baccarat typically carry very low house edges, while some slot side-bets can push the house edge above 10%.
| Game Type | Typical RTP | House Edge |
|---|---|---|
| Slots | 92% – 98% | 2% – 8% |
| Blackjack | ~99% | ~0.5% |
| Roulette (European) | 94% – 97% | 2.7% – 5.3% |
| Baccarat | 98.6% | 1.4% |
Why Does This Matter?
Knowing a game's RTP and house edge before you play is a basic part of responsible, informed gambling. Higher RTP does not mean you will always win — variance (volatility) plays a huge role. A high-volatility slot with 97% RTP can go long stretches without a payout, while a low-volatility game pays out smaller amounts more frequently. Always set a budget, understand the game mechanics, and treat gaming as entertainment rather than a guaranteed income source.
