Betting markets differ across cricket formats — find out which format works best for you.
T20

Test Cricket
A 5-day match with unlimited overs per innings. Long-term bets and session betting are popular. Bangladesh Tigers Test series receive special attention.
The Hundred
100 balls per team. The fastest format, held in England. Unique scoring system and short-match betting markets are available.
Popular Leagues: BPL (Bangladesh Premier League), IPL (Indian Premier League), BBL (Big Bash League), PSL (Pakistan Super League) — live betting on all leagues.
How to Read Odds
The first step to success in betting is understanding odds correctly.
Decimal Odds
The simplest and most widely used method in Bangladesh.
Example: ৳500 bet, odds 1.80
Total return = ৳500 × 1.80 = ৳900
Net profit = ৳900 - ৳500 = ৳400
Implied Probability
The odds show how likely the bookmaker thinks an event is to happen.
Formula: (1 ÷ Decimal Odds) × 100
1.80 odds = (1 ÷ 1.80) × 100 = 55.6%
This means the event has a 55.6% chance of winning.
Other Formats
Different odds formats are used in different countries.
Fractional (British): 4/5 means ৳4 profit for every ৳5 wagered
American: +150 means ৳150 profit on a ৳100 bet; -150 means ৳100 profit on a ৳150 bet

Bankroll Management Guide
Responsible gaming is not just about fun — it is also important for your financial wellbeing. Follow the guidelines below.
Set a Budget
Decide in advance how much you will spend on gaming each week or month. Keep this amount for entertainment only — do not use money meant for living expenses.
Divide into Sessions
Split your total bankroll into smaller sessions. It is wise not to spend more than 10–20% of the total in any single session. This reduces the risk of losing everything in one session.
The 1–5% Rule Per Bet
Keep each bet between 1% and 5% of your total bankroll. Example: if your bankroll is ৳1,000, each bet should be between ৳10 and ৳50.
Strategy for Stopping After a Win
Set a specific profit target (for example, 50% of your starting amount). Once that target is reached, end the session — continuing out of greed increases the risk of losing your winnings.
Track Your History
Note your wins and losses for each session. Reviewing them regularly will help you understand and improve your betting patterns. Remember — gaming is entertainment, not a source of stress.
