Bt399 is an online gaming and Sports Betting platform built with Bangladeshi users in mind. We started with a simple goal — to bring international-standard gaming to people in Bangladesh, right from the comfort of their homes. That goal has never changed.
For a long time, people in Bangladesh faced real frustrations with online gaming — complicated payments, no support in Bangla, slow withdrawals, and security concerns. Solving those problems, one by one, was the whole reason bt399 was built.
At bt399, every improvement we've made has been driven by feedback from our users. We're not just a company — we're part of our community. Every piece of feedback, every complaint, every suggestion matters to us. That mindset is what sets bt399 apart.

Bt399 supports all local Bangladeshi payment methods — Mobile Banking, Nagad, Rocket, and bank transfer. Deposits complete in just 5 minutes and withdrawals in just 15 minutes. That speed and convenience is what makes bt399 the first choice for users across Bangladesh.
Our game library features 500+ titles — slots, Live Casino, Sports Betting, fish games, and much more. Everything is accessible from a single account with no separate logins required. Our partnerships with international game providers ensure that every game on bt399 is fair and verifiable.
Bt399 believes in responsible gaming. We want every member to enjoy themselves, but within healthy limits. That's why we give users the ability to set their own betting limits, take a temporary break when needed, and access professional support resources if required.
The principles that guide everything we do.
