Crash Games — Fast-Paced Thrills
Feel the excitement of Aviator, JetX, and other multiplier games.
How does it work?
In a crash game, each round starts with a multiplier that gradually increases. Place your bet before the round begins, then cash out at the right moment as the multiplier rises. If you do not cash out before the crash, your bet is lost.
- Auto Cash Out: Set a multiplier at which the game will automatically cash out your winnings.
- Short Rounds: Each round lasts just a few seconds to a few minutes.
- Stop Limit: Set a maximum loss limit for yourself before you start playing.
Crash games are fast and exciting, but no "prediction signal" or "crash formula" works. Play responsibly.

Understanding odds before betting makes your decision-making easier.
Decimal Odds
Most betting sites in Bangladesh display odds in decimal format. It is the simplest — the odds number indicates your total return, not your profit.
Odds 1.80 — you bet ৳500.
Total return = ৳500 × 1.80 = ৳900
That means profit = ৳900 − ৳500 = ৳400
Implied Probability
Calculate probability from odds: 1 ÷ odds × 100. Odds of 1.80 means 1÷1.80×100 ≈ 55.6% probability. If you think the real probability is higher, then that bet has value.
| Format | Example | Total return on a ৳500 bet |
|---|---|---|
| Decimal | 1.80 | ৳900 |
| Fractional | 4/5 | ৳900 |
| American (Money Line) | -125 | ৳900 |
