What sets 399 Days promotions apart from the rest?
The number of online betting platforms in Bangladesh keeps growing, but not all promotions are created equal.

Our promotions team understands what Bangladeshi bettors are looking for and builds offers around that. Extra bonuses during Eid, special deals throughout cricket series, and regular cashback all year round — being on 399 Days means there's always something in it for you.
Most importantly, our wagering requirements are among the lowest in the market — meaning bonus funds don't stay locked away. Meet the conditions and the money is yours to use.

Understanding Bonus Terms — What You Need to Know
There's a common misconception about betting bonuses. Many people assume bonus funds can be withdrawn immediately. In reality, every bonus comes with wagering conditions that must be met before a withdrawal is possible. At 399 Days, these conditions are always clearly stated upfront.
What Is a Wagering Requirement?
Say you deposit ৳1,000 and receive a 150% bonus of ৳1,500. With a 5x wagering requirement, you'd need to place a total of ৳1,500 × 5 = ৳7,500 in bets before withdrawing the bonus. At 399 Days, this requirement is one of the lowest in the industry — making it genuinely achievable.
Bonus Expiry
Every bonus has an expiry date. Welcome bonuses are typically valid for 30 days, weekly cashback resets every Monday, and free bets must be used within 7 days of being issued. Any unused bonus expires automatically.
Which matches can I use my bonus on?
Most bonuses can be used on all types of sports bets. However, some special offers may be limited to specific sports or tournaments — for example, the Cricket Season Bonus applies to cricket matches only. You'll find these details listed alongside each offer.
