We're more than just a gaming platform — we set out to create a place where people in Bangladesh can enjoy their favorite games comfortably, safely, and with genuine excitement.
It was 2019. A group of young tech professionals and gaming experts noticed that demand for online gaming in Bangladesh was growing fast — yet there was no platform truly built for local users. Foreign sites didn't speak Bangla, didn't accept bKash payments, and barely paid attention to Bangladeshi cricket.
Aa 51 was born from that realization. The goal was clear — to create a world-class gaming experience for the people of Bangladesh, in the Bangla language, through Bangladesh's own payment systems.
In its very first year, aa 51 earned the trust of thousands of Bangladeshi users — from cricket fans in Chattogram to slots players in Rajshahi, aa 51 quickly became everyone's go-to gaming destination. Now, more than five years on, it stands as one of Bangladesh's most talked-about online gaming platforms.
"We wanted to build a place where anyone in Bangladesh, no matter where they are, gets the same great experience. aa 51 is that vision brought to life."
Aa 51 is active across all 64 districts of Bangladesh. From Dhaka, Chattogram, and Sylhet to Bandarban, Kurigram, and Sunamganj — wherever there's an internet connection, aa 51 is there.
Aa 51 launched as Bangladesh's first mobile-first gaming platform, starting with bKash integration and full Bangla language support.
Aa 51 added live dealer games in partnership with Evolution Gaming and Pragmatic Play Live. The user base surpassed 50,000.
Within just three months of launching the native mobile app, downloads surpassed 100,000. Nagad and Rocket payment integrations were also added the same year.
Live betting and in-play odds updates went live across 35+ sports. Record traffic was recorded during the BPL and IPL seasons.
Aa 51 crossed the 500,000 registered members milestone in Bangladesh. Crash games and Virtual Sports categories were also added this year.
Aa 51 is back with a completely refreshed look — a new UI, faster payment processing, and 50+ game providers.
