Smart Bankroll Management
The most important part of enjoying online gaming is controlling your own budget. Set aside only the amount you can afford to lose without affecting your household — this is called your bankroll.
Set a monthly gaming budget
Decide in advance how much you will spend on gaming each month. Never go beyond that budget.
Split into sessions
Divide your total bankroll across several sessions. Play in a planned way instead of using it all up in one session.
Follow the 1–5% rule per bet
Never place more than 5% of your total bankroll on a single bet. This keeps you in the game over the long term.
Take a break after a win
After a big win, withdraw a portion and set it aside. Avoid the urge to bet all your winnings again.
Stop when you hit your loss limit
If you lose a set amount in one day, stop for that day. Start fresh the next day with a clear head.
Track your gaming history — note how much time you spent on each game and how much you won or lost. This will help you make realistic decisions.
Responsible Gaming
Gaming is for entertainment, not a substitute for income. If you are concerned about your gaming habits, visit our responsible gaming page.
Account Verification Process
The account verification (KYC) process ensures your security and helps prevent fraud. It is a simple, one-time process.
National ID Card (NID)
Clear photos of both the front and back of your Bangladesh National ID Card are required.
Proof of Address
A utility bill (electricity or water), bank statement, or any other official government document is accepted.
Selfie Verification
A clear selfie holding your NID is required — both your face and the ID must be clearly visible.
After Verification
Once verification is complete, all features are fully unlocked — bonuses, withdrawals, and access to the VIP program.
How long does it take?
After documents are submitted, our verification team reviews them promptly. Submitting accurate and clear documents speeds up the process. If you have any questions, contact our 24/7 support team.
