399k has earned the trust of millions of gamers across Bangladesh. Our story, our mission, and our commitment — it's all right here.
399k is more than a gaming platform — it's a vision, a promise
To bring safe, transparent, and world-class online gaming to every corner of Bangladesh. User satisfaction and trust are always our top priority.
To build the most trusted and user-friendly online gaming ecosystem in South Asia, where technology and human service work hand in hand.
Treating every member with honesty. Delivering winnings on time, protecting data, and being there when it matters.
399k has been leading the way since online gaming was just beginning to take hold in Bangladesh. It started small — a dream and a team. But that dream has grown into a platform trusted by millions of Bangladeshi gamers. 399k is more than a website or an app — it's a complete gaming experience where entertainment, security, and transparency are never compromised.
399k was born from a simple question: why should people in Bangladesh struggle on foreign platforms with no support in their own language? Why should making a payment be such a hassle? The search for answers to these questions led to the creation of 399k — a platform designed entirely around the needs of Bangladeshi users.
Our team has taken a deep look at the local market and understands what users here want: fast payments, a simple interface, and support in Bangla. That's exactly what 399k delivers. Deposits and withdrawals via Mobile Banking, Nagad, and Rocket are completed in just a few minutes. Every transaction is fully secure and encrypted. Personal information is never shared with third parties.
When it comes to game variety, 399k offers over 500 titles. From slots to Live Casino, fish games to Sports Betting — every category features internationally acclaimed games. We place equal emphasis on quality and quantity. Every game is regularly tested, fairness is ensured, and results are verified through a Random Number Generator (RNG).
Mobile technology is at the heart of what we do. Since most people in Bangladesh access the internet via smartphone, the entire 399k platform is built with a mobile-first design. Both the Android app and iOS web app load quickly, consume minimal data, and run smoothly even on 3G networks. Game graphics remain crisp on smaller screens thanks to our dedicated mobile rendering engine.
Security is the foundation of 399k. Every account has a two-factor authentication option. Suspicious login attempts trigger an automatic account lock. All fund transfers are processed through SSL encryption at all times. We believe that when users know their account is safe, they can truly enjoy the experience.
Responsible gaming isn't just a rule for us — it's part of our culture. We give users the ability to set deposit limits, offer self-exclusion options, and keep our support team ready at all times to discuss any concerns. 399k wants every member to enjoy the experience within healthy boundaries.
Our customer support team is available 24/7, every day of the week. Chat with us in Bangla via live chat and get answers instantly. When issues arise, we're right there with you — and that commitment is what sets 399k apart.
