Our Journey
399db was founded with a simple but powerful purpose — to create an online platform for gaming enthusiasts in Bangladesh where they can play in their own language, with their own payment methods, and in complete safety. From cricket to slots, blackjack to live casino — 399db has no shortage of entertainment.

Here for you, on your terms — that is our core promise.
We have chosen payment methods with Bangladesh's players in mind. bKash, Nagad, Rocket, Upay, and direct bank transfer — start with a minimum deposit of ৳200. And your winnings will reach your account in as little as 30 minutes to 3 hours. No complications, no hidden conditions.
New members at 399db receive a 150% first-deposit bonus of up to ৳10,000 — with only a 15x wagering requirement. This is one of the best welcome offers on the market. And for regular players, our four-tier VIP program — Bronze, Silver, Gold, and Platinum — offers weekly cashback and special benefits.
Our game library features content from the world's top providers — including PG Soft, Pragmatic Play, JILI, Spribe, Evolution Gaming, NetEnt, Microgaming, Ezugi, and many more.
