As Bangladesh's online entertainment market was gradually growing, one problem stood out — there was no reliable platform where Bangladeshi users could participate in their own language and with their own payment methods. a21 set out to fill exactly that gap.
What started as a cricket-only betting platform quickly grew alongside the demands of our users. Today, a21 covers cricket, football, kabaddi, casino games, lottery, eSports — and more. Our entire team shares one goal: to deliver the best possible experience for every Bangladeshi user.
A21 offers a fully Bangla-language experience. Payments via bKash, Nagad, and Rocket are all supported, and our customer support team speaks Bangla. These are the things that make a21 a truly homegrown platform for Bangladesh.
