The go-to gaming destination for millions of Bangladeshi players since 2020. b399 brings together transparency, security, and entertainment — all under one roof.
B399 is one of Bangladesh's most recognized online betting and gaming platforms. It started with a simple goal: to give Bangladeshi users a space where they could enjoy online gaming safely, transparently, and with genuine fun.
B399 started its journey with cricket Sports Betting. Bangladesh's passion for cricket and the excitement surrounding IPL, BPL, and the T20 World Cup were at the heart of everything from day one. Over time, Live Casino, slots, e-sports, and much more were added to the mix.
B399 now has over 500,000 registered members. Thousands of people spend time in b399's Sports lobby, Live Casino, or slots every single day. Earning that trust has taken a lot of hard work from our team.
Our greatest strength is our team. b399 operates with skilled professionals across four areas: technology, gaming, payments, and customer care. They work continuously to improve the platform so your experience keeps getting better.
