Over 100 million smartphone users in Bangladesh — and a large portion of them are passionate about online gaming and Sports Betting. The problem? Most international apps aren't built for Bangladesh's mobile networks or payment systems. ex644 was created to close exactly that gap.
The ex644 app was built with feedback from real users across Bangladesh — from Dhaka, Chittagong, and Sylhet to users in rural areas. That's why it runs smoothly on 2G/3G networks, uses minimal data, and works on older Android devices.
