Fund your account with Bangladesh payment methods

We accept bKash, Nagad, Rocket and bank transfer so you can top up without international cards. Open your wallet app, send to the account number we display, confirm with your PIN, and the balance lands in your Ok Big wallet within seconds. Withdrawals follow the same rail—request a payout, we verify your identity if it's your first time, then funds return to the same bKash, Nagad or Rocket number you registered. Minimum deposits start low enough for a few spins or a single cricket bet, and there's no fee from our side—your wallet provider's standard charges apply.

SECURITY SIGNALS

How we protect your account and wallet data

We encrypt login credentials and wallet transactions with SSL so data stays unreadable in transit. Passwords are hashed and never stored as plain text—even our team cannot see your original password. Identity verification checks block unauthorized withdrawals: only the account holder who uploaded valid NID documents can request payouts. We log every login and significant account event so you can audit activity in settings. Our servers sit behind firewalls and we apply regular security patches to prevent unauthorized access. Access depends on local law and eligible regions—we restrict signup from locations where online gaming is prohibited.

SSL encryption

Every page and API call uses HTTPS encryption. Your login, wallet balance and personal data travel encrypted, protecting against interception during transmission between your device and our servers.

Identity verification for withdrawals

First-time withdrawal requests require NID upload. We review documents, confirm your identity, then approve. This step blocks fraudulent payout attempts and ensures funds return to the verified account holder.

Password hashing and secure storage

We hash your password using industry-standard algorithms. Plain-text passwords never exist in our database, so even if data were accessed, credentials remain unreadable. Password resets use OTP codes sent to your phone.

Regional access and compliance

Signup availability depends on local law and eligible regions. We block registration from jurisdictions where online gaming is restricted and display access terms clearly during account creation.

What happens when you create or access your account

We ask for your mobile number and send a one-time code to verify it's you. Once confirmed, you set a password and your account goes live. From that point, every login uses your number and password—no email, no extra steps. Your wallet sits inside the account: top up via bKash, Nagad or Rocket, and the

balance appears immediately. Withdrawals require identity verification the first time—upload your NID front and back, wait for approval, then future withdrawals clear faster. If you forget your password, request a reset code on the login screen; the code arrives by SMS and you create a new password on the spot. Your session stays active until

you log out or close the app, so switching between Crash Countdown and live baccarat tables happens without re-entering credentials. We keep login history visible in account settings so you can check recent access and flag anything unusual.

  • Mobile number verification We send an OTP to your number during signup. Enter the code, confirm your identity, and your account activates. No email required—just your phone and the code we send.
  • Password and session security Choose a strong password during registration. Your session persists across the app and web until you log out. We hash credentials and encrypt data in transit to protect your login.
  • Withdrawal verification on first request Upload NID documents when you request your first withdrawal. Our team reviews within hours, approves, and future requests clear faster since we've verified your identity once.
  • Account history and access logs Check login history in settings to see when and from which device you accessed your account. If you spot unfamiliar activity, change your password immediately and contact support.
