Cricket Format Explained — A Bettor's Guide
Learn how to bet on each format in detail.
T20
Each team plays 20 overs. A match typically finishes in 3-4 hours. The most popular format for betting — over/under, number of sixes, and first wicket fall markets are active. BPL and IPL are played in this format.
ODI — One Day
Each team plays 50 overs. A match typically lasts 7-8 hours. The ICC World Cup is played in this format. Understanding the pace of the match is important for bettors — there is an opportunity to reassess at the break.
Test
A five-day match with unlimited overs per innings. The highest standard test in cricket. Session-based bets and the possibility of a draw need to be considered in the betting market.
The Hundred
Each team plays 100 balls — even shorter and faster than T20. This format is popular in England and betting opportunities change quickly.
Popular Leagues
BPL — Bangladesh Premier League, T20 format. IPL — Indian Premier League. BBL — Big Bash League (Australia). PSL — Pakistan Super League. Visit our cricket section to bet on matches in all these leagues.
Account Verification Process — Simple and Transparent
KYC (Know Your Customer) verification ensures the security of your account and prevents fraud. It is an international standard followed by all legitimate platforms.
Required Documents
- National ID Card (NID) — Clear photos of both sides
- Proof of Address — Utility bill or bank statement
- Selfie Verification — A selfie holding your NID
Processing Time
After documents are submitted, the team reviews them promptly. It is generally completed quickly on working days.
After Verification
Once verification is successfully completed, all your features will be activated and withdrawal limits will increase. Once verified, you do not need to do it again.
Bankroll Management Guide
Smart players place the highest importance on budget control.
- Set a gaming budget. Decide in advance how much money you can spend on gaming each month or each week. Make sure this amount does not affect your daily living expenses. Once you set a budget, stick to it strictly.
- Divide into sessions. Split your total budget into smaller sessions. For example, dividing your weekly budget into 3-4 sessions allows you to focus separately on each session, and losing one session does not wipe out your entire budget.
- The 1-5% rule per bet. Spend 1% to a maximum of 5% of your total session balance on a single bet. This rule helps you play for longer and prevents one bad decision from wiping out your entire balance.
- Stop after winning. Set a specific winning target. For example, end the session once you have won 50% or 100% of your starting session balance. Continuing to play out of greed often leads to losing the money you have won.
- Stop after a loss. If you have lost 50% of your session budget, end the session. Placing more bets with the mindset of "recovering losses" generally makes the situation worse. Come back the next day with a fresh head.
- Keep a record of your play. Write it down in a simple notebook or on your phone — when you played, how much you spent, how much you won or lost. This habit will help you understand your own gaming patterns and avoid overspending.
Remember
Gaming is a form of entertainment — not a source of income. Play responsibly and know your limits.
