Log out when your session ends
If you are using a shared or public device, always log out at the end of your session. This keeps your account secure.
Keep Your 399b Account Secure
Security of your online gaming account is the top priority. 399b uses the latest SSL encryption to protect your account. You can also take a few simple steps yourself to keep your account even safer.
Use a strong password
Create a unique password with at least 8 characters, combining uppercase and lowercase letters, numbers, and special symbols. Do not use the same password on other sites.
Log in from your own device
Avoid logging in from a cyber cafe or someone else's device. If you must, use the browser's private/incognito mode and make sure to log out when done.
Use a secure network
Try to avoid logging in from public Wi-Fi. Mobile data or your home network is much more reliable.
Be alert to phishing
If an unknown email or message asks for your 399b login details, treat it as suspicious. 399b never asks for your password by email or chat.
What to Do If You Have Login Problems
Password not working
Check whether Caps Lock is on. If your password is incorrect, reset it using the "Forgot your password?" option. If the reset email doesn't arrive, contact 24/7 live chat.
Can't remember your username
Try logging in with the email address you used during registration. If the problem persists, email [email protected] or get help through live chat.
Page not loading
Clear your browser cache and cookies and refresh the page. Try from a different browser or device. Make sure your internet connection is working.
Account is locked
Entering the wrong password multiple times may temporarily lock your account. Wait a while and try again, or contact 399b support directly through live chat.
Login problems on mobile
If you have issues on mobile, make sure you are using the latest version of your browser and that mobile data is turned on. Trying from Chrome or Firefox works best.

For any login issue, contact 399b's 24/7 live chat support. Support is available in Bengali and issues are resolved quickly.
Log In and Get Exclusive Benefits
Right after logging in to 399b, you get access to one of Bangladesh's top gaming experiences. Get a 120% bonus on your first deposit, up to ৳10,000. For example, deposit ৳1,000 and ৳1,200 in bonus will be added, giving you a total balance of ৳2,200.
The wagering requirement for the bonus is just 20 times, applied only to the bonus amount. That means if you receive a ৳1,200 bonus, wagering ৳24,000 is enough to withdraw your bonus winnings. The minimum deposit is just ৳300.
