Every day, we work to deliver a safe, enjoyable, and fair betting experience for millions of people across Bangladesh. tk3666 is more than just a platform — it's like family to us.
It was 2015. Online betting was still a brand-new concept in Bangladesh. Most people turned to foreign platforms — navigating them in English, dealing with unfamiliar payment methods, with no Bangla support in sight. That problem is what inspired us.
A group of young tech entrepreneurs shared a vision — to build a platform designed for the people of Bangladesh, in Bangla, using the payment methods they already know. That dream is what gave birth to tk3666।
More than a decade on, tk3666 is one of the most trusted online betting platforms in Bangladesh. From Dhaka to Chattogram, Sylhet to Rajshahi — our community spans the entire country.
"We believe betting should be about enjoyment. Safe, fair, and transparent — these are the three values tk3666 stands by every single day."
Bangladesh's first fully Bangla betting platform goes live. 5,000 members in the very first month.
Android app launched. The mobile betting era begins in Bangladesh. User count crosses 100,000.
BKash and Nagad payments launched. Withdrawals in 30 minutes — a first in Bangladesh. 500,000 members.
Evolution Gaming's Live Casino and 500+ slots were added. Active users surpassed 1 million.
IOS app, VIP program, Bangla voice support, and AI-powered analytics. Over 1 million active members.
Six Reasons That Set Us Apart
The entire tk3666 platform is in Bangla — menus, game instructions, support, everything. Anyone in Bangladesh, of any age, can use it with ease.
Win, withdraw — and your money hits your bKash or Nagad within 30 minutes. That's our promise, not just a tagline.
256-bit SSL encryption, two-factor authentication, and an international licence — your personal data and funds are protected to the highest standard.
Ball-by-ball betting on Bangladesh's favourite sport. Over 100 betting markets on every international cricket match — and you'll only find that at tk3666.
Even at 3 a.m., help is available in Bangla. Our support team is on standby 24 hours a day, 7 days a week.
From Bronze to Diamond — earn higher cashback, a dedicated personal manager, and exclusive offers across 5 VIP tiers. The more you play, the more you get.
Whenever someone asks us "Why did you build tk3666?", we always give the same simple answer — because we wanted to create something truly meaningful for the people of Bangladesh. Not just a business, but a community where people can have fun, stay safe, and be rewarded fairly.
Bangladesh's online betting market had serious problems. Foreign platforms didn't speak Bangla, withdrawals took days, and getting support when something went wrong was a real struggle. tk3666 was built to solve all of that.
Tk3666 has one mission — to bring a world-class betting experience to every corner of Bangladesh. Whatever a young person in Dhaka can access, someone in Rangpur or Cox's Bazar should be able to enjoy just as easily. That's our goal.
We believe technology can make life more enjoyable. When the thrill of watching a cricket match meets the excitement of betting — it creates a feeling like no other. Making that experience safer and more fun is what we do.
Behind tk3666 is a powerful technology infrastructure. Our data is distributed across servers around the world so users anywhere in Bangladesh get fast, reliable connections. During live betting, odds update within seconds — and that's only possible because of our advanced technology.
Our mobile app team built the app with everyday Bangladeshi phones in mind. tk3666 runs smoothly even on a Walton or Symphony device with just 2 GB of RAM — because we know what phones most people in Bangladesh actually use.
Every game outcome on tk3666 is determined by an internationally certified Random Number Generator (RNG) — completely neutral and machine-controlled. No human can interfere with the process. We believe fair play is the foundation of lasting trust.
Our payout rate is 98% — meaning for every 100 BDT wagered, an average of 98 BDT is returned to players as winnings. We don't hide this figure; we share it proudly. Because we want our members to play with full knowledge of what they're getting into.
Betting should be fun — not a source of stress. tk3666 lets you set deposit limits, use self-exclusion options, and view your betting history at any time. Our support team is always ready to help — reach out to us whenever you need.
We believe a happy, healthy player is one who stays with our family for the long haul. That's why responsible betting isn't just a policy statement for us — it's the very foundation of how we operate.
