77abc sigma — Bangladesh's
Trusted Gaming Destination
Built with Bangladeshi players in mind, 77abc sigma is a complete online gaming platform — with local payment options, support in Bengali, and a large game library.
How We Got Started
77abc sigma was built around a simple idea — to create a platform for Bangladeshi players where language and payment are never a barrier. Many international sites cannot meet the needs of Bangladeshi users — no Bengali interface, no support for local mobile banking, and no Bengali customer support. 77abc sigma started to fill that gap.
Our platform has been built from the ground up based on the feedback and habits of users in Bangladesh. Familiar mobile banking methods like bKash, Nagad, Rocket and Upay are directly integrated, so you can deposit from as little as ৳100. A wide range of games — the best titles from top providers like PG Soft, Pragmatic Play, Evolution and JILI — are all available in one place.
For those interested in slot games, there is a large library of hundreds of games. And cricket fans can easily place bets on BPL, IPL and T20 World Cup matches through cricket betting. 77abc sigma's goal is to make every user's experience smooth, fast and reliable.
Our Mission
- Ensuring a fully Bengali-language experience for Bangladeshi players
- Fast deposits and withdrawals through local payment methods
- Offering world-class games across a range of categories
- Earning user trust through honesty and transparency
- Promoting responsible gaming practices
