Get Started NowRTP and House Edge Explained — knowledge for smart players
What is RTP (Return to Player)?
RTP is the average amount returned to players per ৳100 wagered in a game over the long term. For example, if a game has an RTP of 96%, in theory ৳96 may come back from a ৳100 bet. However, this is an average across millions of spins — results in a single session can be completely different.
What is House Edge?
House edge is the opposite of RTP — it is the casino's mathematical advantage. If RTP is 96%, the house edge is 4%. This does not mean you will lose every time — it is a statistical average. A big win in the short term is entirely possible.
Typical RTP ranges for different games
- Slot games: typically 92–98%
- Blackjack: around 99% with correct strategy
- Roulette (European): around 97.3%
- Baccarat: typically 95–99%
- Crash games: varies
Why is this important to know?
Knowing the RTP lets you choose games with awareness and plan your budget. A higher RTP means more playing time, but no game guarantees a win. Play responsibly and keep entertainment as your main goal.
How to Read Odds — the basics of betting math
Decimal Odds
The simplest format. Odds of 1.80 mean a ৳500 bet returns a total of ৳900 (profit of ৳400). Calculation: stake × odds = total return.
Implied Probability
Odds tell you the estimated chance of winning. Odds of 1.80 mean 1 ÷ 1.80 = 55.6% probability as estimated by the bookmaker. Comparing this figure with your own analysis can help you find value bets.
Fractional and American Odds
Fractional (e.g. 4/5) is the British format — the ratio of profit to stake. American odds (+150 or -120) is the US format — a positive number shows profit on a ৳100 bet, a negative number shows how much you need to stake to win ৳100.
