Enabling Two-Factor Authentication (2FA) on b644754 is the single most important step you can take to secure your account. With 2FA active, even if someone gets hold of your password, they still can't log in — because every login requires a unique OTP sent directly to your phone.
Steps to enable:
- Log in to your account.
- Tap the profile icon at the top right → select "Account Settings".
- Go to the "Security" section.
- Find the "Two-Factor Authentication" or "2FA" option and toggle it on.
- A confirmation OTP will be sent to your registered mobile number — use it to activate.
Once 2FA is enabled, every subsequent login will require the OTP sent to your mobile. OTPs are typically valid for 5 minutes. A friendly reminder — keep the mobile number registered to your account active, and if you lose your SIM, notify support immediately.
If you can't find the 2FA option in your settings, let us know via live chat — the support team will enable it for you right away.
B644754's policy is One account per person only. Attempting to open multiple accounts using the same mobile number, national ID, or banking details may result in all accounts being permanently closed and all balances forfeited.
However, two members of the same household may maintain separate accounts if they use different mobile numbers, different national ID cards, and different payment methods. That said, operating two accounts from the same device or IP address may trigger a fraud investigation.
The key point is — b644754-'s system automatically detects duplicate accounts. Intentionally operating multiple accounts will result in bonus forfeiture and a permanent ban. If you're unsure, ask via live chat — the support team will assess the situation and advise you accordingly.

If your registered mobile number has also been lost or changed — email support. Provide your name, date of birth, and national ID details, and the support team will manually verify your identity and send a password reset link. This takes up to 24 hours.

Withdrawals are free — no deductions. However, winnings from bonuses require the wagering requirements to be met before withdrawal (see the question below).
Bonus wagering (or rollover) requirements mean you must bet your bonus winnings a set number of times before you can withdraw them. The wagering requirement for b644754's welcome bonus is 15x the bonus amount।
Example: You deposit ৳1,000 and receive a 100% bonus of another ৳1,000. You can withdraw the original ৳1,000 at any time. To withdraw the bonus ৳1,000 — 1,000 × 15 = ৳15,000 Total stake required (win or lose, the total amount wagered is counted).
A few important points:
- Bonuses are valid for 30 days — if wagering is not completed within this period, the bonus will be forfeited.
- Not all games contribute equally to wagering requirements — slots typically count at 100%, Live Casino at 50%, and Sports Betting at 100%.
- A progress bar in the "Bonus" section lets you track your wagering progress from your account.
- If your balance drops close to ৳0 during wagering, the bonus may be forfeited.
To check the terms of a specific bonus, tap the "Terms" link on that bonus or ask support.
An accumulator (Acca) is a way to bet on multiple matches at once — the odds for each selection are multiplied together, and if all bets win, the payout can be huge. On b644754, you may also see this listed as "Parlay" or "Multi".
How to do it:
- Go to the Sports Betting section.
- Click on the odds you want for the first match — it will be added to your bet slip.
- Then select your second, third match the same way — all selections will be added to your bet slip.
- Your bet slip will show an "Accumulator" or "Multi" option — select it.
- Enter your stake and the potential payout will be calculated automatically.
- Tap the "Place Bet" button.
Example: You select 3 matches each with odds of 2.0. Total odds = 2.0 × 2.0 × 2.0 = 8.0. A ৳100 bet wins you ৳800 if all three come in. Lose just one, and the entire bet is lost.
You can add up to 15 selections to an accumulator on b644754. Accumulators with 3 or more selections qualify for a special "Acca Boost" bonus that increases your potential winnings further.
