We believe betting and gaming should be safe, fair, and genuinely enjoyable. c666 was built on that belief — for the millions of people across Bangladesh.
It was 2020. The online betting and gaming market in Bangladesh was growing rapidly, yet there was no truly reliable platform for Bangla-speaking users. Most sites were in foreign languages, payment methods were complicated, and Bangla-language support was nowhere to be found. c666 was born to fill that gap.
A team of seasoned tech professionals and gaming experts shared a vision — to build a platform for Bangladesh where transactions via bKash or Nagad happen instantly, support is available in Bangla, and the games meet world-class standards. That vision became c666.
In just five years, c666 has grown into Bangladesh's most popular online betting platform. From Dhaka to Chattogram, Sylhet to Rajshahi — c666 members can be found in every corner of the country. This is more than just a website; it's a trusted community.
