Our Mission for Players in Bangladesh
Millions of people in Bangladesh are interested in online betting and casino gaming, but they needed a platform that is easy to use, safe, and transparent — available in Bengali. by666 was built with exactly that need in mind — a digital destination where Bangladeshi players can play in their own language, using their preferred payment methods, with complete confidence.
We have one goal — that every player, every time they log in, feels that this platform was made for them. That is why we have set up everything in Bengali, from the interface to customer support. On by666, whether it is cricket betting, slots, or live casino — you will find everything on a single platform.
We believe the foundation of a good gaming experience is trustworthiness. That is why by666 uses SSL encryption technology, a full fair play policy, and measures to ensure the highest level of privacy in every transaction. Your account and your money — both are equally important to us.
For payments, we support Bangladesh's most popular mobile banking methods — bKash, Nagad, and Rocket. Bank transfer is also available. Deposits can start from as little as ৳500, and withdrawals above ৳1,000 are processed within 1 hour. We want your winnings to reach you quickly.
