Five Key Things to Know About Promotions
Welcome Bonus Details
The Welcome Bonus is the first major opportunity for new members — typically awarded as a percentage of your first deposit. To withdraw the bonus, you'll need to meet a specified turnover requirement, meaning the bonus amount must be wagered a set number of times.
How Cashback Is Calculated
Cashback bonuses are generally calculated on a weekly basis. A set percentage of your total wagers or net losses during the period is credited as cashback. This bonus may be added directly to your balance or come with a turnover requirement.
Which Games Are Eligible for Sports Rebate
Sports Rebate applies primarily to cricket, football, and other live Sports Betting markets. Rebate is calculated at a fixed rate based on the total amount wagered per valid bet. Rates and terms may vary by game category and time period.
How to Claim Your Referral Bonus
Existing members can earn a referral bonus by inviting friends or acquaintances to join 399b. Once the referred person registers and makes the required deposit, the first bonus is credited. Full terms and conditions for this program are provided separately.
What Makes Festive Seasonal Offers Special
During Eid ul-Fitr, Eid ul-Adha, Pohela Boishakh, and other festivals, 399b runs exclusive time-limited offers. These are structured differently from regular bonuses — featuring enhanced match bonuses, free play opportunities, or special prize pools. Stay active on your account during these periods to make sure you don't miss out.
Why Promotions Matter During Cricket Season
Bangladesh Team Matches & Promotions
During Bangladesh national team international matches or the BPL, 399b frequently launches special sports bonuses. New offers are added to the Sports Betting section during these periods, and rebate rates may increase.
Special cricket betting promotions are also available during the IPL season. Bangladesh players actively participate in Sports Betting during this time and enjoy rebate bonuses.
Football Leagues & Betting Offers
During the European football season, football betting promotions run actively on the 399b platform. Major matches in the English Premier League, La Liga, or the Champions League may come with special odds boosts or bonus bet offers. Check the platform regularly so you don't miss these deals.
Security & Fairness — The Basics
When logging in and making payments on the platform, your personal information is transmitted via encrypted connections — ensuring third parties cannot access your data.
Use a strong password and never share your account details with anyone. If you notice any unusual activity, change your password immediately.
Slots and casino games typically use RNG (Random Number Generator) technology to determine outcomes, making each round independent and unpredictable.
