An Easy Guide to Understanding Odds
Understanding odds is essential to succeeding at betting. Odds express the probability of an event and the potential amount you can win.
Decimal Odds
The simplest format. Example: odds of 1.80 means if you place a ৳500 bet, your total return will be:
৳500 × 1.80 = ৳900 (Profit: ৳400)
Implied Probability
If the odds are 1.80, the implied probability of winning is: 1 ÷ 1.80 = 55.56%. This means the bookmaker estimates the chance of this outcome happening at around 56%.
Quick comparison of other formats
| Format | Example | Return on ৳500 bet |
|---|---|---|
| Decimal | 1.80 | ৳900 |
| Fractional | 4/5 | ৳900 |
| American (Moneyline) | -125 | About ৳900 |
Useful Tips
The higher the decimal odds, the lower the chance of winning — but you get more if you do win.
Lower odds mean lower risk, higher odds mean higher risk. Always bet within your budget.
Crash Game — Fast Multiplier
A crash game is a fast-paced game where a multiplier slowly rises and can "crash" at any moment. You need to cash out before it crashes.
Aviator (Spribe)
A plane flies through the sky as the multiplier climbs. If you don't cash out before the plane flies away, you lose your entire bet.
How to Play
- Place your bet before the round starts
- Watch the multiplier rise
- Press the cash out button before it crashes
- If you set auto cash out, it will exit automatically at your chosen multiplier
Warning
Set a stop limit for yourself before you play. Do not trust any "signals" or "predictions" — every round is completely random.
