We wanted to build a clean, honest, and fast gaming experience for Bangladeshi players. That vision is what started cl666.
As online gaming and betting platforms grew in Bangladesh, most were not built with local users in mind. English-only interfaces, slow payment systems, and no Bangla support — these were the pain points that led our team to start building cl666 in 2020.
We had one goal: build a platform for Bangladeshi players where everything is simple, fast, and in Bengali. Deposits and withdrawals via Mobile Banking, Nagad, and Rocket, live support in Bengali, and a mobile-first design — these have been cl666's core features from day one.
Within just a few years, cl666 has become one of Bangladesh's most popular online gaming destinations. Today, over 500,000 registered members enjoy slots, fish games, casino, and Sports Betting on cl666 every day.
We're more than just a gaming site — we're a trusted partner for Bangladeshi players
To give every player across Bangladesh a safe, fair, and enjoyable online gaming experience — in plain Bangla, with simple payments.
To establish ourselves as South Asia's most trusted and user-friendly online gaming platform — where technology and a human touch work together.
