Aviator and Crash Games — How They Work
A crash game is a fast-paced multiplier game where a plane (or rocket) starts flying and the multiplier keeps rising. Your goal is to cash out before the plane crashes.
Each round lasts only a few seconds to a few minutes. When placing your bet, you can set an auto cash-out multiplier — for example, it will cash out automatically once it reaches 2.0x.
Important: Set a stop limit before you play. Waiting too long out of greed can mean losing everything in a crash. Do not trust any "signals" or "predictions" — crash game outcomes are completely random.
Play on mobile from anywhere
Most players in Bangladesh play on mobile — it runs on low data, you can deposit with one tap via bKash or Nagad, and you can bet while watching live cricket matches. The 77kb app runs on Android 7 or later and takes up no more than around 100 MB of space.

Bankroll Management — the key to smart play
1. Set a Budget
Decide in advance how much money you can spend on entertainment each week or month. This amount should come from outside your food, rent, or other essential expenses. Never exceed your budget.
2. Divide into Sessions
Split your total bankroll into smaller sessions. For example — if you have ৳5,000 in total, spend ৳500 per session. This way, one bad session cannot wipe out your entire bankroll.
3. The 1–5% Rule Per Bet
Never spend more than 1% to 5% of your total bankroll on a single bet. This keeps you in the game over the long term and protects you from large losses.
4. Set a Limit and Stop When You Win
Set a target — for example, stop when your bankroll grows by 50%. Risking more on the back of a win often erases all your winnings.
5. Take a Break When You Lose
If you lose several bets in a row, end the session and take a break. Rushing to chase lost money by placing more bets is likely to result in even bigger losses.
6. Track Your Play History
Write down each session's deposits, wins, losses, and withdrawals in a simple notebook or phone note. This habit will help you understand your own patterns and make informed decisions.
RTP & House Edge — Important to Understand
RTP (Return to Player) is a percentage that indicates — on average, how much money may come back for every ৳100 wagered over the long term. For example, a 96% RTP means an average of ৳96 comes back for every ৳100 bet. However, this is not a guaranteed promise — it is a statistical average across millions of spins.
The typical RTP range varies by game type. Slot games generally show an RTP of 92% to 98%. Card games like blackjack can have an RTP close to 99%. Roulette typically ranges from 94% to 97%.
House edge is the opposite of RTP. A 96% RTP means the casino's house edge is 4%. This difference is the casino's business model. It is wise to check a game's RTP before choosing to play it.
A higher RTP does not guarantee more winnings — especially in high-volatility games, where rewards come less often but are larger. Low-volatility games offer smaller but more frequent rewards.
| Game Type | Typical RTP | House Edge |
|---|---|---|
| Slots | 92% – 98% | 2% – 8% |
| Blackjack | ~99% | ~1% |
| Roulette | 94% – 97% | 3% – 6% |
| Crash Game | Variable | Variable |
