Cricket Formats Explained — A Guide for Bettors
Understanding the different formats of cricket helps in making informed betting decisions.
T20
20 overs per team. A match typically finishes in 3 to 4 hours. Live betting markets are most active in this format — with opportunities to bet ball by ball.
Leagues: IPL, BPL, PSL, BBL
ODI (One-Day)
50 overs per team. A full match runs for 7 to 8 hours. Betting markets on wickets, run rate and partnerships require a different type of strategy.
Examples: ICC Cricket World Cup, Bangladesh Tigers series
Test
Up to 5 days, 2 innings per team. Session-based betting markets are available. Three-way betting (win/loss/draw) is common due to the possibility of a draw.
Series: Country vs country series, ICC WTC
The Hundred
100 balls per team. In this newer format played in England and Wales, each innings finishes in just 60 to 90 minutes. It offers fast-paced betting opportunities.
League: The Hundred (England)
How to Read Odds — A Guide for Beginners
Understanding odds is essential before starting to bet. Odds express both probability and potential return.
Decimal Odds
The most commonly used format on betting sites in Bangladesh.
Example: You place a bet of ৳500 at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900 (including original stake), net profit ৳400.
Fractional Odds
For example 4/1 — meaning ৳4 profit on a ৳1 bet. Mainly used in British horse racing betting.
American Odds
+150 means ৳150 profit on a ৳100 bet; -120 means you need to bet ৳120 to win ৳100.
Implied Probability
If the decimal odds are 1.80, the implied probability = 1 ÷ 1.80 ≈ 55.6%. This means the bookmaker believes the chance of that outcome is around 56%.
Crash Game — Fast Multiplier Game
Learn how popular crash games, including Aviator, work.
A crash game is a fast-paced multiplier game where a plane (or rocket) takes off and the multiplier keeps rising — until it suddenly "crashes".
How a Round Works
Place your bet before the round starts. Once the plane takes off, the multiplier rises from 1.00x. Cash out before the crash to win — wait too long and you lose everything.
Auto Cash Out
Set a multiplier in advance (e.g., 2.00x) — when that value is reached, your bet will be cashed out automatically.
How Short Is a Round?
A round ends in just a few seconds to one or two minutes. Quick decision-making is essential.
⚠️ Important Warning
Set a stop limit for yourself before playing. There is no guarantee of winning, and do not trust any "predictions" or "signals".

Account Verification Process (KYC Guide)
Learn why verifying your account is important and how the process works.
Why Is KYC Required?
Every account holder's identity is verified in accordance with international security standards and to prevent money laundering. This keeps your account protected from unauthorized access.
Through verification, you will be able to make larger withdrawals and enjoy VIP benefits.
What Documents Are Required?
- National ID (NID): Front and back photos of a valid Bangladeshi national identity card.
- Proof of Address: A recent utility bill or bank statement (within the last 3 months).
- Selfie Verification: A recent selfie taken while holding your NID.
- Payment Verification: A screenshot of your mobile wallet or bank account details.
Processing Time
Verification is usually completed within 1–24 hours. Submitting during office hours speeds up the process. Our support team will keep you updated while verification is in progress.
What Happens After Verification?
Once verification is successful, your account will be fully activated — your maximum withdrawal limit will increase, VIP benefits will be unlocked, and faster payment processing will be guaranteed.
Bankroll Management Guide — Advice for the Smart Bettor
Bankroll management is the most important skill for enjoying gaming over the long term. An experienced bettor always sets a budget before playing.
Set a Budget
Only spend money on gaming that you can afford to lose without affecting your daily life. Set aside a fixed gaming budget for each month.
Divide Into Sessions
Break your monthly budget into weekly amounts, and from there into a set amount for each gaming session. Never spend your entire budget in a single session.
The 1–5% Bet Rule
Place a maximum of 1–5% of your total bankroll on each bet. Following this rule means a bad streak cannot wipe out your entire budget.
Stop After a Win
Set a "win target" in advance — for example, stop when you have made a 50% profit on your session bankroll. Making emotional decisions after a win is the biggest mistake.
Track Your History
Note your wins and losses from each session. This will help you understand which games you are doing well in and where you are having problems.
Responsible Gaming Tools
bdbig believes that safe and responsible gaming is the most enjoyable gaming experience.
Self-Exclusion
The option to temporarily close your account for a set period (from 1 week to 5 years).
Deposit Limits
Set your own daily, weekly, or monthly deposit limit — changes take 24 hours to take effect.
Loss Limits
Decide in advance the maximum loss you can accept over a given period.
Session Time Limits
Set a maximum time for each gaming session — when the time is up, you will be logged out automatically.
Reality Check Reminders
At regular intervals, a summary of your gaming time and losses/winnings will be shown on screen.
Self-Assessment Quiz
Use our self-assessment quiz to evaluate whether gaming is having a negative impact on your life.
For Ages 21+ — Get Help
If you feel gaming is getting out of your control, please contact our 24/7 live chat immediately. Our Bengali-speaking support team will help you take a self-exclusion and get the assistance you need. Gaming is for entertainment only — never think of it as a source of income.
