How to Play
- Place your bet before the round starts

How to Read Odds
Understanding odds makes betting much more effective. In Bangladesh, Decimal Odds are most commonly used.
Decimal Odds Example
You bet ৳500 at odds of 1.80. If you win, your total return will be: ৳500 × 1.80 = ৳900. Your profit will be ৳400.
Implied Probability
The implied probability of 1.80 odds is ≈ 55.6%. Formula: 1 ÷ odds × 100. The lower the odds, the higher the bookmaker considers the probability of the event.
Odds Format Comparison
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳100 → ৳180 return |
| Fractional | 4/5 | ৳4 profit on a ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet |

Bankroll Management Guide
The most important part of responsible gaming is managing your money properly. Following the guidelines below will let you play enjoyably over the long term.
- Set a budget: Before you start playing, decide the maximum amount you are willing to spend. This amount should not affect your daily life.
- Divide into sessions: Split your total budget into smaller sessions. For example: divide a ৳2,000 budget into 5 sessions of ৳400 each — this ensures longer-lasting entertainment.
- Follow the 1–5% betting rule: Each bet should not exceed 1% to 5% of your total session budget. This is the most effective way to make your bankroll last longer.
- Take a break after a win: After a big win, take a short break and withdraw a portion of your winnings. It is wise not to place all your winnings back as bets.
- Set a loss limit: If you lose 50% of your set limit in a session, stop that session. The mindset of chasing losses is harmful.
- Keep a record of your play: Track how much you deposit and how much you win or lose. This information will keep you aware of your own gaming habits.
