We're more than just a betting site. 666b is a home for millions of sports fans across Bangladesh — a place to bet safely, transparently, and with genuine excitement.
When 666b launched in 2019, the goal was simple — to build an easy, safe, and genuinely fun betting platform for Bangladesh's cricket and football fans. Back then, online betting meant complicated interfaces, slow payments, and everything in English. Nobody was thinking about the people who spoke Bangla and sent money through bKash.
We're here to fill that gap. 666b was built with the people of Bangladesh in mind — in Bangla, with local payment methods, and with genuine respect for Bangladesh's sports culture. The thrill of betting on Mustafizur's bowling during the IPL, the rush of a BPL final — we've brought that excitement to the digital world.
Today, 666b is one of Bangladesh's leading online betting platforms, with over 5 million registered members active every day. From Dhaka to Chittagong, Sylhet to Rajshahi — the 666b community spans the entire country.
We believe betting should be a form of entertainment — not a source of stress. That's why 666b actively promotes responsible gaming. Set your limits, play within them, and enjoy the game.

There's no shortage of online betting platforms in Bangladesh. What sets 666b apart is that it was built for Bangladeshi players from the ground up. Where other foreign platforms simply translated their interface into Bangla, 666b rethought the entire experience with Bangladesh in mind.
Our emphasis on cricket is no accident. In Bangladesh, cricket is more than a sport — it's passion, it's identity. That's why 666b offers dedicated markets, special promotions, and the highest number of betting options for every major cricket tournament. A single BPL match on our platform can open over 100 betting markets — from the toss right through to Man of the Match.
People in Bangladesh run their lives on bKash and Nagad. That's why 666b has built around these payment methods from day one. Our payment system is so seamless that many members say depositing on 666b feels just as easy as a bKash recharge.
We've put special focus on withdrawals. On many platforms, getting your money out can take hours or even days. At 666b, withdrawals are processed in an average of 2 minutes — a result of our investment in technology and a testament to our commitment to our customers.
Security is the first question on everyone's mind when transacting money online. 666b gets that. Our platform uses 256-bit SSL encryption — bank-grade security. You also have the option to enable two-factor authentication (2FA) on every login.
Our server architecture is also built so that if one component encounters an issue, the rest of the system keeps running without interruption. That's why downtime on 666b is virtually zero — even on match days, our servers run at full speed.
At 666b, responsible gaming isn't just a policy on paper. Every member can set their own daily, weekly, and monthly betting limits directly on the platform. There's also an option to temporarily suspend your account if you need a break. We believe a happy, in-control bettor is our best long-term partner.
In 2026, 666b is moving forward with even bigger plans. New games, enhanced VIP benefits, broader sports coverage, and faster payment systems — our team is actively working on all of it. Our goal remains the same: to deliver the best online betting experience to every sports fan in Bangladesh.
