How to Read Odds
Understanding odds is the most important step before you start betting. sis6 displays odds in a simple decimal format.
Decimal Odds
Decimal odds are the easiest to follow. Multiply your bet amount by the odds to get your total return, including your original bet.
Example:
You bet ৳500, odds 1.80
Total return = ৳500 × 1.80 = ৳900
Profit = ৳900 − ৳500 = ৳400
Implied probability
Odds of 1.80 mean the event has an implied probability of about 55.6% (1 ÷ 1.80 × 100). The lower the odds, the higher the chance of winning.
Comparing other formats
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳1.80 returned for every ৳1 bet |
| Fractional | 4/5 | ৳4 profit for every ৳5 staked |
| American | -125 | ৳100 profit on a ৳125 bet |
