RTP and house edge explained
What is RTP (Return to Player)?
RTP, or "Return to Player", is a percentage that indicates how much of the total amount wagered is returned to players over the long term. For example, if a game has an RTP of 96%, the expected average return on every ৳100 wagered is ৳96. This is a long-term statistical figure — results may vary in the short term.
Typical RTP ranges for different games
RTP varies across casino games. Slot games generally show an RTP of 92%–98%. In blackjack, applying the correct strategy can push the RTP to around 99%. European roulette carries an RTP of approximately 97%. Baccarat typically has an RTP close to 98%–99%.
What is house edge?
House edge is the inverse of RTP — it is the casino's mathematical advantage. If the RTP is 96%, the house edge is 4%. This margin covers the casino's operating costs and keeps services running. House edge differs from game to game — it is generally lower in table games and higher in lottery-style games.
Why is this important to know?
Understanding RTP and house edge helps you make informed decisions. Choosing games with a higher RTP means a greater chance of playing for longer. Keep in mind, however, that every spin or round is an independent event, and winning is not guaranteed. Always play within a set budget.

What Is a Betting Exchange?
A betting exchange is a platform where you bet against other players — not against a casino or bookmaker. This means the odds are often the best available in the market.
Back vs Lay — a simple example
Say you believe Bangladesh will win in a Bangladesh vs India cricket match:
- Back Bet: Place ৳1,000 on Bangladesh to win — if they win, you receive ৳2,500 (at odds of 2.5).
- Lay Bet: Place ৳1,000 on Bangladesh to lose — you profit if India wins, and lose if Bangladesh wins.
An exchange typically takes a small commission from winning bets. With a regular sportsbook you can only Back; on an exchange you can also Lay.
| Item | Back Bet | Lay Bet |
|---|---|---|
| Meaning | Bet on a team to win | Bet on a team to lose |
| Possible on a bookmaker? | Yes | No |
| Possible on an exchange? | Yes | Yes |
| Odds set by | Market / players | Market / players |
| Commission | Applied to winnings | Applied to profit |
