Betting Exchange
Learn how an exchange differs from a standard bookmaker.
With a standard sportsbook, you bet against the site. With a betting exchange, you bet against other players — the platform only takes a commission.
Back vs Lay — A Simple Explanation
Back bet: You think something will happen — for example, Bangladesh will win the match. You Back ৳1,000 at odds of 2.0. If Bangladesh wins, you make a profit of ৳1,000.
Lay bet: You think something will not happen — Bangladesh will lose. You Lay ৳1,000 at odds of 2.0. If Bangladesh loses, you receive ৳1,000; but if they win, you must pay ৳1,000.
On the exchange, odds are set by other players, not by the platform. The platform takes a small commission on winnings.
| Feature | Back | Lay |
|---|---|---|
| What You Think | Event will happen | Event will not happen |
| Risk | Stake amount | Odds × stake |
| Who uses it | Casual bettors | Experienced bettors |
| Example | Bangladesh will win | Bangladesh will lose |
RTP and House Edge Explained
RTP, or "Return to Player", is a mathematical measure of what percentage of total wagers a game returns to players over the long term. For example, if a slot has an RTP of 96%, it means an average of ৳96 comes back for every ৳100 wagered — but this is an average across millions of spins, not a guarantee for any single session.
The RTP range varies by game type. Slot games typically fall between 92% and 98%. Strategy-based games like blackjack can deliver an RTP of close to 99% when played with the correct strategy. For roulette, the European version generally sits around 94–97%.
House edge is the flip side of RTP — it is the platform's mathematical advantage. If a game has an RTP of 96%, the house edge is 4%. This means the platform retains an average of 4% on every bet. The longer you play over time, the more the house edge mathematically takes effect.
To play more wisely, it is worth choosing games with a higher RTP, setting a budget, and not treating RTP as a guarantee of profit. It is a statistical average — the outcome of each round is random and independent.

Bankroll Management Guide
Play responsibly and enjoy it for the long run.
-
Set a budget
Before you start playing, decide on a fixed amount you can afford to lose. Treat this money as an entertainment expense — never play with money meant for living costs or savings. -
Divide into sessions
Split your total budget into smaller sessions. For example, if your weekly budget is ৳2,000, it is better not to spend more than ৳500 per session. This way, one bad session cannot wipe out your entire budget. -
The 1–5% per bet rule
Keep each bet within a maximum of 1–5% of your total session budget. If your session budget is ৳500, keep each bet between ৳5 and ৳25. This helps you play longer and manage a bad streak. -
Know when to stop after a win
After a good win, it is wise to withdraw a portion of the profit. Set a specific profit target and stop when you reach it. Avoid the habit of putting all winnings back into bets. -
Take a break after a loss
Rushing to increase your bets to recover losses (chasing losses) is the most harmful habit. Set a fixed loss limit and end the session when you reach it. -
Track your play history
Keep a simple record of your wins, losses, and total spending. This will give you a realistic picture and help you keep your spending under control.
