How to Read Odds
Understanding odds is essential to successful betting. There are three common odds formats — Decimal, Fractional, and American.
Decimal Odds (Easiest)
Example: Odds 1.80
You place a ৳500 bet. If you win, you receive: ৳500 × 1.80 = ৳900 (including ৳400 profit)
Formula: Total payout if you win = Stake × Odds
Implied Probability
To find the probability from decimal odds: 1 ÷ Odds × 100%. Odds of 1.80 means a 55.6% probability — meaning the bookmaker considers this outcome slightly more likely.
Odds Format Comparison
| Format | Example | Explanation |
|---|---|---|
| Decimal | 2.50 | Total return of ৳250 on a ৳100 bet |
| Fractional | 3/2 | ৳3 profit on a ৳2 bet |
| American | +150 | ৳150 profit on a ৳100 bet |

Bankroll Management Guide
The most important aspect of responsible gaming is controlling your budget. Experienced players always set aside a fixed budget and never go beyond that limit.
- Set a gaming budget: Decide in advance how much you will spend on gaming each month. Set an amount that, even if lost, will have no impact on your daily life.
- Divide into sessions: Split your total budget into smaller sessions. Play with a limited amount in each session — this way you can enjoy more time.
- Follow the 1–5% rule: Do not place more than 1% to 5% of your total session budget on any single bet. This helps maintain balance over the long term.
- Stop after a win: Take a break after a good win. Rather than betting it all back in the heat of the moment, set some aside.
- Set a loss limit: Decide in advance the maximum you are willing to lose in each session. Once you reach that limit, end the session.
