Learn About RTP and House Edge
RTP, or "Return to Player", is a statistic showing the percentage of total bets that a game returns to players over the long term. For example, if a game has an RTP of 96%, there is theoretically an average chance of ৳96 coming back for every ৳100 wagered — however, this does not apply in the short term; it is the average result across millions of spins.
The typical RTP range varies across different game categories. Slot games generally show an RTP of 92%–98%. In blackjack, applying optimal strategy can bring the RTP close to 99%. In roulette, the European version typically has an RTP of 94%–97%.
House edge is the flip side of RTP — it is the casino's expected profit rate. Games with a lower house edge are more favorable for players. Read the game information before placing bets and set your own budget — this is the core principle of responsible gaming.
Volatility (Variance) is another important factor. High volatility games pay out less often but in larger amounts; low volatility games pay out smaller prizes more frequently. Choose a game that suits your preference.
