About 399o — Built for
Bangladesh's Betting Community
399o was created with a single purpose: to give players across Bangladesh a reliable, fair, and entertaining online betting and casino experience in English — backed by fast local payments, real sports coverage, and a support team that actually answers. This is who we are and what we stand for.
How 399o Started — and Where We Are Today
399o was founded by a team of sports enthusiasts and technology professionals who shared a frustration: Bangladesh had no truly local, English-language online betting platform that understood how people here actually play, deposit, and withdraw. International platforms were available, but they were clunky on Bangladeshi mobile networks, didn't support bKash or Nagad natively, and offered little understanding of what matters most to players in Dhaka, Chittagong, Sylhet, Rajshahi, and beyond — cricket, first and foremost, followed by football, live casino tables, and a handful of fast-action slot games.
The founding team set out to build something different. 399o launched as a focused sports betting platform with cricket at its core — covering BPL, IPL, ICC T20 World Cup tournaments, Test matches featuring the Bangladesh Tigers, and international bilateral series as they happen. From day one, the platform was designed to be accessible on Android and iOS mobile browsers without requiring any app download, because most players across Bangladesh access the internet primarily through their phones.
The payments integration was a priority from the start. 399o partnered directly with bKash and Nagad — the two most widely used mobile financial services in Bangladesh — to offer instant deposits and withdrawals in BDT. Players in Cox's Bazar or Barisal can fund their 399o account in under 30 seconds, just like paying at any local shop. Rocket, Upay, Dutch-Bangla Bank, BRAC Bank, and City Bank round out the payment offering for players who prefer alternative channels.
Over time, 399o expanded its offering significantly. The live casino section was introduced featuring real-time tables from Evolution Gaming and Ezugi — Speed Baccarat, Dragon Tiger, Andar Bahar Live, Teen Patti Live, and Immersive Roulette among others. The slots lobby followed, bringing in titles from Pragmatic Play, NetEnt, and Microgaming — plus crash games like Aviator from Spribe, which rapidly became one of the most-played products on the platform among younger players in Dhaka and Chittagong.
Today, 399o covers more than 60,000 sporting events every month, operates a live casino with hundreds of table variants, hosts a slots library of 500+ certified titles, and processes thousands of BDT transactions daily. The platform is available 24 hours a day, seven days a week, and is staffed by an English-language support team operating on Bangladesh Standard Time (UTC+6). Every player on 399o must be 21 years of age or older — age verification is enforced at registration and at the point of withdrawal, without exception.
399o remains committed to the values it launched with: transparency in odds and payouts, fairness certified by independent game auditors, responsible gaming tools built into every account, and a product that performs reliably on the mobile networks and payment systems that Bangladeshi players depend on every day.
What 399o Stands For
Our platform is built on six core principles that guide every product decision, every support interaction, and every payment integration we make.
What Makes 399o Different
There are other betting platforms available to Bangladeshi players. Here is why thousands choose 399o as their primary account.
Built for Bangladesh — Every City, Every Device
399o is designed for adults aged 21 and above across Bangladesh who want a reliable, English-language betting and casino platform that understands their local context. Our primary audience is mobile-first — most of our players access 399o via smartphone browser, often during or after a cricket match, from Dhaka's Gulshan district to the coastal areas around Cox's Bazar.
The platform serves players in every major Bangladeshi city: Dhaka, Chittagong, Sylhet, Rajshahi, Khulna, Barisal, Rangpur, Mymensingh, and beyond. We optimise the platform's load speed and data usage for the network conditions typical in each region — whether on Grameenphone, Robi, Banglalink, or Teletalk connections.
Our players include cricket fans who want to add extra excitement to a BPL evening, football supporters who follow the Premier League and La Liga in addition to domestic BD football, casino enthusiasts who prefer the social feel of a live Baccarat table over a slot machine, and casual players who enjoy a quick round of Aviator during a lunch break. 399o is built to serve all of them equally well, from a single account, with a single login.
Every player on 399o must be aged 21 or above. We enforce this requirement seriously because responsible gaming starts with ensuring our platform is used only by adults who can make informed decisions about entertainment spending. If you are under 21, 399o is not for you — full stop.
399o takes its responsibility to players seriously. Gambling is entertainment — it is not a reliable way to make money, and it carries real risks if not approached with discipline. Every 399o account comes pre-equipped with free responsible gaming tools: deposit limits, loss caps, session time controls, reality-check pop-ups, cooling-off periods from 24 hours to six weeks, and permanent self-exclusion available on request with no questions asked.
If you or someone you know is struggling with gambling, contact the 399o English support team at any time — available 24/7 on Bangladesh Standard Time. All responsible gaming tool activations are immediate and confidential. For more detail, visit the 399o Responsible Gaming page. 🔞 21+ Only
