We're more than a gaming site — we're the entertainment partner of millions across Bangladesh. Delivering a safe, fair, and enjoyable experience is at the heart of everything 5666tk does.
Online gaming in Bangladesh used to be a chaotic space — no reliable payment options, no Bengali-language support, and zero assurance of security. To fill that gap, 5666tk— and so the journey began.
Our founding team brings together veterans of Bangladesh's tech and gaming industries. As gamers themselves, they knew exactly what a Bangladeshi player needed. Fast payments, support in Bengali, and honest gameplay — these three pillars were the foundation on which 5666tk was established.
