Four Ways 644 Keeps Your Session Moving
We designed each feature to save you time and keep the focus on the game. Download the APK or log in through your browser — your balance, bet history and open rounds sync across both so you never lose your place. Our payment row sits right above the lobby so you can top up mid-session without leaving the page, and bilingual support answers questions in English or Bengali the moment you ask.
APK and Browser Sync
Install the Android APK or open the mobile site — your account, wallet balance and game progress stay identical across both so you can switch devices without re-entering anything.
Passwordless Login
Enter your phone number, confirm the OTP we send, and you're in. No passwords to remember, no recovery emails — just your number and the code that arrives in seconds.
Cricket and Football Markets
We cover IPL, BPL and international cricket alongside football leagues so you can place live bets during the match. Odds update in real time and settle the moment the final ball is bowled.
Daily Bonus Board
Check the promo tab each morning for reload offers, slot feature spins and cashback on settled bets. New rewards appear every day and credit to your account wallet the moment you claim them.
How We Keep Your Account and Payments Safe
Every login, deposit and withdrawal at 644 moves through multiple layers of protection so your money and personal details stay private. We encrypt the connection between your phone and our servers, verify every transaction with an OTP, and store payment records in your account history so you can check each transfer whenever you want. Our system never shares your bKash, Nagad or Rocket number with third parties, and all personal data sits behind access controls that restrict who can view it.
SSL Encrypted Connection
We use SSL encryption to secure the data traveling between your device and our platform. That means your login credentials, wallet numbers and transaction details are scrambled in transit so no one else can read them.
OTP Login Verification
Every time you sign in, we send a one-time code to your registered phone number. You confirm the code, we verify it matches, and only then does the session open — an extra checkpoint that blocks unauthorized access.
Transaction Records
Your account history logs every deposit, withdrawal, bet and settlement with a timestamp and transaction ID. You can review each entry anytime to confirm amounts, check dates and reconcile your wallet balance.
Personal Data Handling
We store your phone number, email and payment details in a restricted database that only authorized staff can access. We never sell your information to third parties and we delete inactive data according to our retention schedule.
Three Promotions You Can Check Right Now
We rotate offers every few days so returning players always find something new on the promo board. Each reward credits to your account wallet once you meet the stated terms, and you can track progress in the bonus tab. Availability depends on your region and account status, so log in to see which promotions are live for you today.

Live Casino, Slots and Sports in One Screen
We pack Evolution live dealer tables, Pragmatic Play and PG Soft slot rooms, and our full sportsbook into a single scrollable lobby so you never need to jump between apps. Open Baccarat Golden when you want the live dealer experience, switch to Bangladesh Night Spins 501 or Rocket Payout Track for slot features, or head to the sports tab and bet on IPL, BPL or Premier League matches in play. Every game loads in under three seconds on mobile data, and your wallet balance updates the moment a round settles so you always know where you stand.

bKash, Nagad, Rocket and Bank Transfer
We built the deposit flow around the mobile wallets Bangladesh players already use every day. Tap the payment row, pick your method, enter the amount, and follow the two-step confirmation in your wallet app. Deposits usually clear in under a minute, and withdrawals reverse the same path so funds land back in the account you sent from. Verification happens once per wallet number — after that, every transfer is just amount plus PIN.
Select bKash in the payment row, enter the amount you want to add, and the system shows you our merchant number.
Request a withdrawal from your account wallet, choose Nagad, and enter your registered Nagad number. We verify the request with an OTP sent to your phone, then process the transfer.
Pick Rocket on the deposit screen, type the amount, and we display the Rocket merchant code. Switch to your Rocket app, send the payment, and return to 644 — your wallet updates automatically the moment our system confirms the incoming…
For larger amounts, select bank transfer and enter your bank account details. We provide our receiving account number and reference code.
644Android APK and iOS Web App
We offer an Android APK you download directly from our site and an iOS web-app shortcut you add to your home screen. Both give you one-tap access to the full lobby, live tables and sportsbook without opening a browser each time. Your login session, wallet balance and bet history sync instantly across the APK, the web app and the desktop site so you can start a round on your phone during the commute and finish it on your laptop at home. The APK auto-updates in the background whenever we release a new version, and the iOS shortcut always points to the latest mobile site so you never need to reinstall.
Live Chat, Email and Phone Support
Our support team answers questions about deposits, withdrawals, game rules and account verification every day from morning through late evening Bangladesh time. Reach us through the live-chat icon in the bottom corner of any page, send an email with your account ID and question, or call the Bangladesh support line shown in your account dashboard. We reply to live chat within a few minutes during peak hours and handle email tickets within twenty-four hours. All agents speak English and Bengali so you can ask in whichever language is easier.
Live Chat
Tap the chat bubble on any screen, type your question, and an agent picks it up within minutes. Live chat is the fastest way to resolve deposit mismatches, unlock bonus credit or confirm withdrawal status because the agent can see your account in real time and fix issues on the spot.

Casino and Sports Glossary
Quick definitions for the terms you see in game rules, bonus offers and bet slips. Each entry explains what the word means in plain language so you know exactly what you're agreeing to before you place a bet or claim a reward.
The total amount you must wager before you can withdraw bonus credit. If a bonus has a five-times rollover, you need to bet five times the bonus value on eligible games before the funds unlock.
Placing a bet on a cricket or football match while it is still in progress. Odds update every few seconds based on the current score and game situation, and you can cash out early if the option is available.
Return to Player — the percentage of total wagers a slot or table game is programmed to pay back over millions of rounds. A ninety-six percent RTP means the game returns ninety-six cents for every dollar wagered on average over time.
A single bet that combines multiple match outcomes into one slip. All selections must win for the bet to pay out, but the combined odds multiply together so the potential return is much higher than individual bets.
How often a slot pays and how large those payouts tend to be. High-volatility games pay less frequently but offer bigger wins when they hit; low-volatility games pay smaller amounts more often.
Closing a live bet before the match finishes and taking the current profit or cutting your loss. The cash-out amount updates in real time based on the match score and remaining time.
The smallest amount you can request to transfer from your 644 wallet back to your bKash, Nagad or Rocket account. Check the payment page for the current limit, which varies by method.
