18+ By signing in you confirm you are 18 years of age or older and agree to gb99b's Terms & Conditions and Privacy Policy. Please play responsibly.
How to Sign In
Signing in to your gb99b account takes less than 30 seconds. Follow these steps to access your account from any device — mobile or desktop.
Open gb99b in Your Browser
Navigate to the gb99b platform using Chrome on Android or Safari on iOS. No app download or APK installation is required — the entire platform runs smoothly in your mobile browser, including live video streams on 4G connections used across Dhaka and Chittagong.
Click the Login Button
On the gb99b homepage, locate the login button in the top navigation area. This will open the secure sign-in interface where you can enter your account credentials.
Enter Your Mobile Number
Type your registered Bangladeshi mobile number (the number you used during account registration) into the mobile field. Include the country code +880 or use the local 11-digit format — both are accepted.
Enter Your Password
Type your account password into the password field. Passwords are case-sensitive. If you are on a trusted personal device, you may enable the "Remember me" option to stay signed in between sessions.
Complete Two-Factor Authentication
If you have two-factor authentication (2FA) enabled on your gb99b account, you will receive an OTP (one-time password) via SMS to your registered number. Enter the OTP in the verification field to complete the secure login process.
Access Your Account Dashboard
Once authenticated, you are taken directly to your personal gb99b dashboard where you can view your account balance, active bonuses, recent transaction history, open live casino tables, or place cricket and sports bets immediately.
New Account Registration
Don't have a gb99b account yet? Registration is fast, free, and open to all adults aged 18 and above residing in Bangladesh. Here is everything you need to know before signing up.
What You Need to Register
To create a gb99b account you need a valid Bangladeshi mobile number, a secure password of at least 8 characters, and confirmation that you are 18 years of age or older. No email address is required at registration — your mobile number serves as your primary account identifier throughout your time on the platform.
Registration Takes Under 2 Minutes
The gb99b registration form is intentionally minimal to get you playing as quickly as possible. Fill in your mobile number, choose a strong password, confirm you meet the 18+ age requirement, and agree to the platform terms. Your account is active and ready to use immediately after submitting the form.
KYC Verification for Withdrawals
While you can deposit and play immediately after registration, your first withdrawal requires identity verification (KYC). You will need to submit a photo of your National Identity Card (NID) or passport. KYC approvals typically take 15 minutes during staffed support hours. Players from Sylhet, Rajshahi, Khulna, and all other divisions of Bangladesh follow the same straightforward KYC process.
Welcome Bonus for New Members
New gb99b account holders may be eligible for a welcome bonus on their first qualifying deposit. Before depositing, check the active promotions page and opt in to any eligible welcome offer. Bonus terms — including wagering requirements and eligible games — are displayed in full on each promotion. Always read the terms before opting in.
Account Security
gb99b takes the security of your account seriously. Multiple layers of protection are applied to every account on the platform, from registration through to every login session and withdrawal.
When creating your gb99b password, choose a string of at least 10 characters combining uppercase letters, lowercase letters, numbers, and symbols. Avoid using your mobile number, date of birth, or common patterns like "123456" or "password". A strong, unique password significantly reduces the risk of unauthorised account access, protecting both your account balance and your personal information stored on the platform.
gb99b payment credentials — your bKash PIN, Nagad authentication codes, and bank account details — are processed exclusively through the respective payment gateway systems and are never stored on gb99b servers. When you initiate a bKash deposit or withdrawal from your gb99b account, the payment authentication happens entirely within the bKash ecosystem; gb99b only receives confirmation of a successful transaction, not your PIN or authentication details.
Login Troubleshooting
Having trouble signing in to your gb99b account? Here are the most common login issues and how to resolve them quickly.
Forgotten Password
If you cannot remember your gb99b account password, use the "Forgot Password" option on the login screen. You will receive a password reset link or OTP via SMS to your registered mobile number. Follow the instructions in the message to set a new password. If you no longer have access to your registered number, contact gb99b support via WhatsApp or live chat for account recovery assistance.
OTP Not Received
If you have 2FA enabled and your OTP SMS has not arrived within 60 seconds, first check your mobile signal strength — this is particularly relevant for players in areas of Cox's Bazar, Rangpur, Mymensingh, and Barisal where network coverage can be intermittent. Try resending the OTP. If the issue persists, contact gb99b support who can assist with alternative verification for your account.
Account Temporarily Locked
After multiple failed login attempts, gb99b temporarily locks the account as a security precaution to prevent unauthorised access. If your account is locked, wait 30 minutes before attempting to log in again with the correct credentials, or contact gb99b's 24/7 live chat support to have the lock reviewed and lifted immediately after identity confirmation.
Page Not Loading or Login Errors
If the gb99b login page is not loading correctly, try clearing your browser cache and cookies, then reload the page. Switching from Wi-Fi to mobile data (or vice versa) can also resolve temporary connectivity issues. Ensure you are using an up-to-date version of Chrome (Android) or Safari (iOS). If problems persist, gb99b support is available 24/7 via live chat.
