The whole process is done within a few minutes. If you run into any trouble, contact our live chat — we are available 24/7 to help.
Before large withdrawals or to protect your account, 644j may sometimes ask you to verify your identity. Typically you will need to submit a photo of your national ID card or passport. The verification process is quick and your information is kept completely confidential. Completing verification on time makes the withdrawal process smoother.
Deposits and Withdrawals
644j currently supports four deposit methods: bKash, Nagad, Rocket and bank transfer. All methods are easily accessible for users in Bangladesh and every transaction is secured with SSL encryption. Choose whichever method you prefer and follow the on-screen instructions to deposit.
The minimum deposit at 644j is ৳300 and the minimum withdrawal is ৳800. These limits apply to all payment methods — the same rules apply whether you use bKash, Nagad, Rocket, or bank transfer. Start with a small amount and build up your experience at your own pace.
Deposits made via bKash, Nagad, or Rocket usually reflect in your account balance within a few minutes. Bank transfers may take a little longer. If more than 15 minutes have passed, contact our live chat with your payment reference number and we will resolve it quickly.
Withdrawal requests at 644j are typically processed within 5 to 30 minutes. This is among the fastest turnaround times of any online gaming platform in Bangladesh. After you submit a withdrawal request, the funds will be sent directly to your bKash or Nagad number. Having your account verified in advance makes the process even smoother.
644j does not charge any deposit or withdrawal fees. However, your mobile banking provider (such as bKash or Nagad) may apply their own transaction charges — contact your provider directly for details. There are no hidden charges on 644j's side.

To place bets on tournaments like the BPL (Bangladesh Premier League) or IPL, go to the cricket section at 644j. You can place bets before a match starts or at any point during a live match. A wide range of betting options is available, including match winner, total runs, and top batsman. Review the odds carefully before placing a bet and wager within your own budget.
Yes, 644j is a fully mobile-friendly platform. You can play directly in the browser on any Android or iOS smartphone or tablet — no separate app download is needed. The games are optimised for mobile screens, so both graphics and performance remain excellent.
RTP (Return to Player) is the theoretical percentage of total wagers that a game returns to players over the long term. It is an average figure only — results in any individual session may vary. A higher RTP generally indicates better long-term odds. This information is usually found on the game's info page. All games at 644j are designed to ensure fair play.
In the 644j live casino section you can play with real dealers in real time. Baccarat, Blackjack, Roulette, and many other games are available via live streaming. Log in to your account, go to the live casino section, pick the table you want, and start playing straight away. A stable internet connection will give you the best experience.
Bonuses and Promotions
New members receive a 120% bonus on their first deposit, up to a maximum of ৳15,000. For example, depositing ৳1,000 gives you a ৳1,200 bonus — bringing your total balance to ৳2,200. Depositing ৳26,000 gives you the maximum bonus of ৳15,000 — for a total of ৳41,000. To claim the bonus, select the relevant option at the time of your deposit.
A wagering requirement is the condition that specifies how many times you must wager the bonus amount before you can withdraw it. For the 644j welcome bonus, this is 25 times (25x). That means if you receive a ৳1,200 bonus, you must place a total of ৳30,000 in wagers before withdrawing. Once the requirement is met, you can withdraw your winnings with ease.
The 644j VIP program has three tiers — Bronze, Silver, and Gold. You move up automatically through regular play. Bronze members receive up to 0.5% weekly cashback, Silver up to 1.0%, and Gold up to 1.5%. Higher tiers also come with additional special benefits and priority service.
No. The welcome bonus applies to new members on their first deposit. However, 644j regularly runs various promotions, reload bonuses, cashback offers, and special events — such as dedicated betting offers during the BPL season or gifts during Eid. Check our promotions page regularly for the latest offers.
Bonuses can be used on most games, but some games or betting markets may contribute at a lower rate toward meeting the wagering requirement. Check the full bonus terms and conditions or ask us in live chat — we will clearly tell you which games give you the most from your bonus.
