We believe online gaming should be fun, safe, and accessible to everyone. That's the vision 666cb was built on, and the same commitment drives us to this day.
When 666cb launched in 2019, the online gaming landscape in Bangladesh was far from user-friendly. Most platforms operated in English, payment options were limited, and no one was really thinking about the specific needs of Bangladeshi users. 666cb was built to fill exactly that gap.
From day one, our goal was to build a platform where people in Bangladesh could play in their own language, using payment methods they already know. When Mobile Banking and Nagad started gaining popularity across the country, we seized that opportunity and introduced direct deposits and withdrawals via mobile wallet.
Today, 666cb is more than a gaming site – it's a household name. Thousands of users come here every day to bet on cricket, spin slots, and enjoy fish games. Their trust in us is our greatest reward.
Integrity and transparency are the foundation of everything we do. Every game on 666cb uses RNG (Random Number Generator) technology, which is regularly audited by independent third-party organizations. Results are entirely random and cannot be predetermined by anyone. We want every player to enjoy the experience with complete peace of mind.
User security is our top priority. 666cb uses SSL encryption to keep your personal information and financial transactions fully protected. Thousands of transactions pass through our system every day, and every single one is secured.
We never compromise on customer support. Live chat in Bengali is available 24/7. Whether you have a problem or a question, our team is always there – with most issues resolved within 5 minutes. Our support team is built specifically for Bangladeshi users, so there's no language barrier.
666cb takes responsible gaming seriously. We want our platform to always be a source of enjoyment, never a source of problems. To that end, we offer tools like deposit limits, self-exclusion, and cooldown periods so every user can set boundaries that work for them.
