RTP and House Edge Explained
RTP, or Return to Player, is a measure of the percentage of total bets that a game returns to players over the long term. For example, a 96% RTP means that on average ৳96 is returned for every ৳100 wagered — but this is a long-term average statistic, not a guarantee for every session.
Regarding the typical RTP range for different game categories — slot games generally have an RTP of 92% to 98%, blackjack can reach close to 99% with correct strategy, and roulette typically falls between 94% and 97%.
House edge is the inverse of RTP — it is the average percentage of each bet that the casino retains over the long term. A 5% house edge means the casino keeps an average of ৳5 per ৳100 over the long term. This is fixed for a given game and does not change.
Understanding RTP before you play is important because it helps you choose the right game and manage your budget. Choosing a higher RTP game means your money will last longer, though there is no guarantee of a big win.
| Game Type | Typical RTP Range |
|---|---|
| Slot Games | 92% – 98% |
| Blackjack | 98% – 99%+ |
| Roulette (European) | 94% – 97% |
| Baccarat | 98% – 99% |
| Crash Games | Variable |
