How to Read Odds
Understand decimal, fractional, and American odds before you start betting
Decimal Odds (Easiest)
With decimal odds, total return = stake × odds. Example: a ৳500 bet at odds of 1.80 returns a total of ৳900 (৳400 profit).
Implied Probability
To find the chance of winning from odds: 1 ÷ odds × 100. For example, odds of 2.00 gives a 50% probability, odds of 1.50 gives roughly 67%. Lower odds mean a higher probability — but also a smaller payout.
Comparing Other Formats
| Format | Example | Meaning |
|---|---|---|
| Decimal | 2.50 | ৳250 back on a ৳100 bet |
| Fractional | 3/2 | ৳3 profit on ৳2 |
| American | +150 | ৳150 profit on a ৳100 bet |

RTP and House Edge Explained
Knowing these two concepts is important before choosing a game
RTP (Return to Player) is the theoretical percentage a game returns to players over the long term. For example, if a slot has an RTP of 96%, it means that over a long period, an average of ৳96 is returned for every ৳100 wagered and the casino keeps ৳4. This is not a guarantee — a single session can result in either a big win or a big loss.
House edge is the flip side of RTP: subtract RTP from 100% to get the house edge. Slots generally show an RTP of 92–98%, blackjack can reach close to 99% with correct strategy, and various roulette variants fall within 94–97%.
Understanding volatility or variance is also important. High-volatility games pay out less frequently but in larger amounts, while low-volatility games deliver smaller wins more often. Choosing volatility to match your budget and preference is a smart move.
Finally, keep in mind — RTP is a long-term statistic. It may not be fully reflected in a single day's session or a few hundred spins. So set a mindful budget before you start playing.
