Crash Games
A crash game is a fast-paced type of game where a multiplier gradually rises and can "crash" at any moment. The earlier you cash out, the safer you are — but waiting longer means a higher potential reward.
Aviator (Spribe) is the most popular game in this category. Each round lasts just a few seconds to a few minutes — making it ideal for playing on mobile while on the go.
How a Round Works
- Set your bet amount before the round begins.
- Once the plane takes off, the multiplier starts rising — from 1.00x upward.
- You can "Cash Out" at any time and win according to the multiplier at that moment.
- If a crash happens before you cash out, your bet is lost.
Important: Set a stop limit for yourself before you start playing. There are no "predictions" or "signals" in crash games — every round is independent and the outcome is completely random. Play responsibly.
Cricket Formats Explained
Betting markets differ across formats — understanding the right format makes it easier to place smart bets.
20 overs per team, match typically ends in 3-4 hours. Betting markets are more dynamic — odds change every over. BPL (Bangladesh Premier League), IPL, and T20 World Cup use this format.
One-Day International — 50 overs per team, a 7-8 hour match. Mid-match betting, top batter bets, and Man of the Match markets are popular.
A long five-day format where each team bats twice. Series betting, session bets, and match draw bets are a highlight here.
A new English format — 100 balls per team. Extremely fast-paced and spectator-friendly. Ends in just 2.5 hours.

How to Read Odds
Understanding betting odds is the first step to smart wagering. Learn about the three main formats.
Decimal Odds
The most common format in Europe and on bt21.
৳500 × 1.80 = ৳900
(Profit ৳400, including the original stake returned)
Implied probability: 1 ÷ 1.80 = 55.6%. This means the bookmaker estimates the chance of that outcome at ~56%.
Fractional Odds
Traditionally used in British cricket betting.
৳500 × (4÷5) = ৳400 profit
(Total return ৳900)
Decimal conversion: (4÷5) + 1 = 1.80
American Odds (Moneyline)
Common in American sportsbooks.
+150 means ৳150 profit on a ৳100 bet.
bt21 generally uses the decimal format.

Bankroll Management Guide
The most important aspect of responsible gambling is managing your own budget. Following the guidelines below keeps the playing experience enjoyable and reduces the risk of financial loss.
-
1. Set a gambling budget
Decide in advance how much you can spend on entertainment each week or month. This amount should never come from your living expenses or savings. -
2. Divide it into sessions
Split your total budget into smaller sessions. For example, if your monthly budget is ৳2,000, set ৳200–৳300 per session. Stop when a session's funds run out. -
3. The 1–5% rule per bet
Never place more than 5% of your total bankroll on a single bet. If your bankroll is ৳1,000, the maximum per bet is ৳50. This rule keeps you in the game over the long run. -
4. Decide to stop after a win
Set a "win target" in advance. When you reach the target, end the session — the mindset of continuing to win often leads to losses. -
5. Set a loss limit
Stop immediately when your session's set funds are gone. Placing more bets to "chase losses" almost always leads to even bigger losses. -
6. Keep a record of your play
Regularly note down how much you deposited, how much you withdrew, and the results of each game. This will help you understand your own playing patterns.
Quick Reference Card
Remember: Gambling is for entertainment, not a source of income. Never bet with borrowed money.
Responsible Gambling Tools
bt21 believes that gaming should always be enjoyable and controlled. That is why we provide you with several protective tools.

Loss Limits
Decide in advance the maximum amount you can lose within a given period. When the limit is reached, your account will be automatically blocked.
Session Time Limits
Set how long you play in each session. When the time is up, you will receive a reality-check reminder.
Self-Exclusion Option
You can temporarily or permanently exclude yourself from the platform. Contacting support will make it effective immediately.
Self-Assessment Quiz
Check whether your gaming habits are healthy. Our self-assessment quiz helps you stay aware.
Reality-Check Reminders
Pop-up messages will appear at set intervals to remind you how long you have been playing and how much you have won or lost.

Privacy Policy Notice
bt21 places the highest importance on protecting your personal information. We only collect data necessary for account management and service improvement. Your data is never sold to third parties. Read our Privacy Policy and learn about your rights.
Legal Notice
bt21 operates as an online platform. We do not claim any specific license or regulatory approval.
Bangladesh's Public Gambling Act 1867 was enacted before online betting existed — so the country's legal position on online gambling is not yet clearly defined. We want to be transparent about this legal ambiguity.
Users are fully responsible for complying with the local laws of their own country. Before using bt21, please make sure you are aware of the laws applicable in your area.
Age Restriction: This platform is for those aged 21 and above only. Registration by minors is strictly prohibited.
