3666 is more than just a betting site. It's the go-to destination for millions of people in Bangladesh seeking entertainment, excitement, and the thrill of winning. We believe that honest, transparent, and responsible gaming should be accessible to everyone.
3666 was born from a simple question — don't the people of Bangladesh deserve an online betting platform where everything is in Bangla, payments go through bKash, and support is available even in the middle of the night?
3666 was built to answer exactly that question. From day one, our focus has been on putting Bangladeshi users first — through cricket excitement, Eid celebrations, Pohela Boishakh festivities, and every season in between, 3666 is right there with you.
Many platforms claim to serve Bangladesh, but everything's in English, payments are a hassle, and support is nowhere to be found. That's exactly where 3666 is different.
"We want every person in Bangladesh — whether in the city or a village — to have a safe and enjoyable gaming experience. 3666 is our commitment to making that a reality."
Today, 3666 has over 500,000 registered members — from Dhaka, Chattogram, and Sylhet to small towns across rural Bangladesh. Thousands of successful withdrawals happen every day, and new members join every day. That trust is our greatest reward.
3666's platform, built specifically for Bangladeshi users, went live — and thousands of members signed up on the very first day.
After integrating bKash and Nagad payments, membership grew rapidly. Withdrawal times were brought down to just 5 minutes.
World-class Live Casino tables are now live. Andar Bahar, Baccarat, and Blackjack — all available with real live dealers.
Our exclusive VIP Program is now live — featuring loyalty points, cashback, and special perks for regular members.
3666 is now Bangladesh's most recognized and trusted betting platform — with new games and offers added every week.
What drives every decision we make
Our goal is to bring a safe, seamless, and enjoyable online betting experience to every corner of Bangladesh. We want every 3666 member to play with peace of mind — where win or lose, the experience is always a good one.
Fair odds, transparent payments, and responsible gaming — these are three principles 3666 never compromises on.
Our mission is to establish online betting in Bangladesh as something respectable, entertaining, and responsible. We want 3666 to be a name that people trust the moment they hear it.
3666's goal is to become South Asia's most trusted Bangla-language betting platform by 2030.

Those who are with 3666 know — when we say something, we mean it. Payments are never delayed, bonuses are easy to withdraw, and when something goes wrong, support actually helps. These basics are hard to find on many other platforms.
Many new players are entering Bangladesh's online gaming scene. When they visit a platform for the first time, they're often filled with doubt — will I get my money back? Is this site legitimate? 3666 wants to put those fears to rest. That's why all our terms and conditions are written in clear Bangla, so no one is left confused or taken advantage of.
Responsible gaming doesn't mean betting is wrong. People play for fun and bet for the thrill — that's perfectly normal. But 3666 wants to make sure no one bets beyond their means. That's why our platform offers daily deposit limits, self-exclusion, and cooling-off periods.
All game providers at 3666 are internationally licensed. Every game uses an RNG (Random Number Generator), ensuring no outcome is ever manipulated in anyone's favor. Fair play is something we never compromise on.
