We believe gaming should be transparent, fun, and accessible to everyone. 3666bef was built with exactly that in mind — with players from every corner of Bangladesh at heart.
When 3666bef launched in 2020, the goal was simple — to build an online gaming platform for everyday people in Bangladesh that is easy to use, hassle-free for payments, and guarantees withdrawals after a win.
Our founding team consists of seasoned professionals with extensive experience in the gaming industry. They noticed that Bangladeshi players often struggled with language barriers, payment issues, and unreliable support on foreign platforms. 3666bef was built to fill that gap.
Today, 3666bef is one of the fastest-growing online gaming platforms in Bangladesh. From Dhaka to Chittagong, Sylhet to Rajshahi — players from every district across the country play on 3666bef daily and win.
Official operations launch in the Bangladeshi market with a small but passionate team. 10,000 members in the first month.
The 3666bef app launches on Android and iOS. Mobile user numbers triple.
Real-time live dealer games and the popular Fish Game section were introduced.
In just three years, registered members on 3666bef surpassed 500,000. Daily payouts now exceed BDT 5,000,000.
With enhanced security, a faster payment system, and over 300 game titles, 3666bef grows stronger.
