Crash Games — Fast and Thrilling
Crash games are one of the most thrilling formats in online betting. In this type of game, a multiplier starts at 1x and gradually increases — until it suddenly crashes. Your job is to cash out before the crash.
How a Round Works
Place your bet before the round begins. Once the plane (or rocket) takes off, the multiplier starts rising. At any point, pressing the cash-out button multiplies your bet by the current multiplier and adds the amount to your balance.
Aviator (Spribe) is one of the most popular crash games in Bangladesh. JetX is another well-known title. Both games feature an auto cash-out option — you can set a multiplier in advance and the game will cash out automatically at that point.
Play with Caution
Crash game rounds are very short — just a few seconds to a few minutes. This fast pace can sometimes encourage players to play many rounds in a row. So before you start, set a stop-loss limit for yourself — decide in advance how much you are willing to lose before stopping for the day. Do not trust any "prediction tools" or "signal groups" — every round is determined completely independently.

What Is a Betting Exchange
On a standard sportsbook, you always bet against the platform — the platform sets the odds and you either accept them or not. A betting exchange is completely different: here, other players create the odds and bet against each other. The platform simply takes a commission in the middle.
Back vs Lay — An Example
Back Bet: You think Bangladesh Tigers will win today's match. You Back ৳500 at odds of 2.20. If the team wins, you receive ৳500 × 2.20 = ৳1,100 (total), meaning a profit of ৳600.
Lay Bet: You think the opposing team will not win. You Lay ৳500. If the team does not win, you receive the full ৳500 minus commission — but if the team wins, you must bear the specified loss. This is essentially like taking an insurance position.
| Back Bet | Lay Bet |
|---|---|
| Betting that an outcome will happen | Betting that an event will not happen |
| What the majority of bettors do | Acting as the bookmaker |
| Maximum loss — the bet amount | Maximum loss — the liability |
| Odds are set by others | You set the odds yourself |
On an exchange, odds are formed directly from the supply and demand of other players. The platform usually takes a small commission on the winnings of the winning side.
Bankroll Management Guide
1. Set a gaming budget
Decide how much of your monthly income you can set aside for entertainment. Make sure that losing this amount will not affect your daily life. Never take money from emergency funds, savings, or your family budget for gaming.
2. Divide into sessions
Split your monthly budget into smaller sessions. If the monthly budget is ৳3,000, set aside ৳100 for each day. If you run out in one session, stop playing for that day.
3. The 1–5% rule per bet
Place only 1% to 5% of your total session balance on a single bet. If your session balance is ৳1,000, one bet should be a maximum of ৳50. Following this rule gives you a chance to keep playing even after a loss.
4. When to stop after winning
Set a profit target — for example, stop when you are up 50% of your session balance. Even during a winning streak, do not place large bets out of overconfidence.
5. Rules for stopping after a loss
End the session when 30–50% of your session balance is gone. Increasing your bet size to recover losses ("chasing losses") is very dangerous and one of the main causes of large losses.
6. Track your history
Record each session's deposits, withdrawals, and results in a notebook or spreadsheet. At the end of the month, see where you lost the most — this information will help you improve your strategy.

Beware of Fake Sites and Scams
As online betting grows in popularity, the number of fraudulent sites and scams has also increased. A few simple precautions can keep you safe.
Always confirm in your browser that you are on 77sb.cam and that the URL begins with HTTPS. Even a slight spelling change can be a sign of a fraudulent site.
Do not share your bKash, Nagad, or Rocket PIN or OTP with anyone — even if they claim to be a 77sb support agent. Our support team will never ask for an OTP or password.
77sb's official support will never ask for your password, personal PIN, or full card number.
Be cautious if someone claiming to be an "official agent" on social media or Telegram offers you special bonuses or deposit deals. These are often fraudulent.
Change your 77sb password immediately and inform our support team via live chat. Also alert your mobile banking provider.
