About b399 — Bangladesh's Premier Online Casino & Sports Betting Platform
b399 was built from the ground up for Bangladeshi players — fast local payments, cricket-first betting markets, a world-class live casino, and a commitment to safe, responsible gaming. This is who we are and why we built b399.
How b399 Was Built for Bangladesh
b399 was founded with a single, clear purpose: to build an online gaming and sports betting platform that Bangladeshi players could genuinely call their own. The founders of b399 saw the same problem everywhere: international platforms accepting players from Bangladesh but offering no local payment methods, no cricket-first betting markets, no Bangla-relevant promotions, and customer support that barely acknowledged the time difference between London and Dhaka. b399 was the answer to that gap.
From the very first line of product development, b399 was architected around the realities of the Bangladeshi internet user — mobile-first browsing on mid-range Android devices, 4G data connections shared across families in Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, and Barisal, and a deep cultural connection to cricket that no generic sportsbook could replicate with a generic template. The b399 platform loads fast, deposits via bKash and Nagad settle in under 60 seconds, and the cricket lobby treats BPL, Bangladesh Tigers fixtures, and ICC tournaments as headline events — not afterthoughts buried in a sidebar.
Since launch, b399 has grown into one of the most recognised online casino and sports betting brands serving the Bangladesh market. The platform has continuously expanded its game library, payment options, and responsible gaming tools in direct response to player feedback gathered from users across every major division of Bangladesh — from Cox's Bazar on the Bay of Bengal to Rangpur in the north. Every product decision at b399 is filtered through a single question: does this make things better for our players in Bangladesh?
b399 operates transparently and with integrity. All games on the platform are provided by internationally certified studios — Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi — whose RNG (Random Number Generator) systems are independently audited and published. b399 does not develop its own game logic; instead, we partner exclusively with providers whose certification credentials are available for verification. This means every spin, every hand, and every crash multiplier on b399 is governed by audited, fair-play technology.
b399 Is Born
The b399 project begins with a founding team determined to build Bangladesh's first genuinely local online gaming platform — bKash-native, cricket-first, and mobile-optimised from day one.
Sports Betting & Live Casino Launch
b399 expands beyond slots into full live casino streaming via Evolution Gaming and Ezugi, and introduces comprehensive cricket betting markets covering BPL, IPL, and international Bangladesh Tigers fixtures.
Nagad, Crash Games & Responsible Gaming Tools
Nagad and Rocket payment integration is completed, Aviator by Spribe joins the crash games lobby, and b399 rolls out its full suite of player-controlled responsible gaming tools — deposit limits, session timers, and self-exclusion.
Bangladesh's Most Complete Gaming Platform
b399 now serves players across all eight divisions of Bangladesh, offering live casino, sports betting, slots, crash games, and seasonal promotions tied to Eid, Pohela Boishakh, and BPL season — all through a single unified account.
Why b399 Exists and Where We Are Going
Every decision at b399 is anchored in a clearly defined mission and a long-term vision shaped entirely around the needs of players across Bangladesh.
Our Mission
To provide every adult player in Bangladesh with a safe, fair, and genuinely enjoyable online gaming and sports betting experience — powered by local payment methods, enriched by cricket-first content, and protected by world-class security and responsible gaming infrastructure. b399 exists to make premium online entertainment accessible to players across Dhaka, Chittagong, Sylhet, and every corner of Bangladesh, without the friction, exclusion, or mistrust that comes with using platforms built for other markets.
Our Vision
To become the undisputed number-one trusted online gaming destination for Bangladesh — a platform that Bangladeshi players actively recommend to friends and family because the experience is fast, fair, and built for them. Our long-term vision includes expanding responsible gaming education across Bangladesh, deepening our cricket content during every BPL and ICC season, and continuously improving payment processing speeds so that bKash and Nagad transactions at b399 remain the fastest in the market.
The b399 promise to every player: Your account is protected by 256-bit SSL encryption and monitored continuously for fraud. Your funds in the b399 wallet are held separately from operational capital. Your game outcomes are determined by independently certified RNG systems — not by b399. Your responsible gaming settings, once activated, cannot be overridden or shortened by b399 support staff. And your personal data is never sold to third parties. These are not marketing claims — they are the operational standards b399 holds itself to on behalf of every registered player in Bangladesh.
What b399 Offers Bangladeshi Players
b399 is not a single-product platform. It is a fully integrated gaming destination covering every category of online entertainment that matters to players across Bangladesh.
Cricket & Sports Betting
b399 treats cricket as the flagship sport it is in Bangladesh. The sportsbook covers Bangladesh Tigers home and away fixtures, BPL (Bangladesh Premier League) season-long markets, IPL, T20 World Cup, ICC Champions Trophy, and major international test series. Pre-match, in-play, and accumulator betting are all available. Football, kabaddi, hockey, and tennis markets round out the full sports offering.
Live Casino
The b399 live casino streams real dealers 24 hours a day across Baccarat, Roulette, Blackjack, Teen Patti, Andar Bahar, Crazy Time, Monopoly Live, and Lightning Roulette. Tables are streamed by Evolution Gaming, Pragmatic Play Live, and Ezugi — three of the world's most recognised live casino technology providers. Table volumes increase during peak Bangladesh Standard Time (BST, UTC+6) evening hours.
Slots & RNG Games
With over 500 slot and RNG game titles from Pragmatic Play, NetEnt, Microgaming, and other certified studios, the b399 slots lobby covers every style — classic three-reel, video slots, Megaways, jackpot progressives, and feature-buy titles. All published RTP percentages are sourced directly from the provider and displayed on each game information panel.
Crash Games
Crash games are among the fastest-growing categories at b399. Aviator by Spribe leads the lobby, alongside other multiplier-format titles popular with Bangladeshi mobile players. These lightweight, fast-paced games are ideal for standard 4G connections and load in seconds regardless of whether you are in central Dhaka or a smaller town like Comilla or Jessore.
Local Payment Methods
b399 was built around Bangladeshi payment infrastructure from day one. Deposits and withdrawals via bKash and Nagad are processed in under 60 seconds for verified accounts. Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, Islami Bank, Sonali Bank, Visa, and Mastercard are also fully supported. All balances are held in BDT — there is no currency conversion to deal with.
Promotions & Bonuses
b399 runs a regular calendar of promotions relevant to Bangladeshi players — a 100% first deposit welcome bonus up to ৳20,000, BPL season cricket cashback offers, Eid and Pohela Boishakh seasonal promotions, free spins campaigns tied to new slot releases, and reload bonuses for existing players. All wagering terms are clearly displayed inside the promotions panel for full transparency.
The Principles That Guide Everything at b399
Our values are not a poster on a wall. They are the criteria we apply when building new features, resolving player issues, evaluating new game providers, and deciding which payment partners to integrate. Every team at b399 — product, support, payments, compliance — operates by these five principles.
Player First, Always
Every product and policy decision at b399 is evaluated first by asking how it affects the player experience. Fast deposit processing, transparent bonus terms, and responsive support are not aspirations — they are minimum standards we hold ourselves to on behalf of every registered b399 player in Bangladesh.
Fair Play, No Exceptions
b399 does not influence game outcomes. All casino games on the platform use certified RNG technology provided and maintained by the game studios — not by b399. We publish game RTPs, bonus wagering requirements, and withdrawal terms clearly because fairness requires transparency, not just intent.
Security Without Compromise
Player accounts, payment data, and personal information at b399 are protected by 256-bit SSL encryption, continuous anti-fraud monitoring, OTP two-factor authentication, and a strict KYC verification process. We treat security as non-negotiable infrastructure — not an optional feature.
Responsible Gaming as a Core Product
Responsible gaming tools at b399 are built into the core account dashboard — not buried in a terms page. Deposit limits, session timers, cooling-off periods, and self-exclusion are all one-tap away after login. b399 takes seriously its obligation to support players who need help managing their play.
Local Relevance at Scale
b399 is a global-standard platform built with a local mindset. We invest continuously in cricket content, local payment integrations, BST-aligned support hours, and promotions that reflect the Bangladeshi calendar — from Eid celebrations to Pohela Boishakh and every BPL season in between. Being relevant to players in Dhaka, Rajshahi, Sylhet, and Khulna is not a marketing strategy — it is the product strategy.

Our Commitment to Safe Play
b399 is an entertainment platform for adults aged 18 and above. We do not accept registrations from players under 18, and all accounts are subject to age and identity verification before any withdrawal is processed. This is not optional — it is a fundamental operating standard at b399.
We recognise that for a small number of players, gambling can become a problem that affects their finances, relationships, and wellbeing. b399 takes this seriously. Every registered player has access to a full suite of responsible gaming tools directly from their account dashboard — no need to contact support, no waiting period, no forms to fill in. Set a deposit limit, activate a session timer, request a cooling-off period, or initiate a self-exclusion in seconds.
If you believe your gambling is becoming a problem, we encourage you to use the self-exclusion tool available in your b399 account, or to contact our support team directly at [email protected]. b399 support staff are trained to handle responsible gaming requests with discretion and urgency. Self-exclusion requests are processed as a priority and take effect within 24 hours of confirmation.
Deposit Limits
Set daily, weekly, or monthly deposit caps on your b399 account. Limits take effect immediately and cannot be increased until the current limit period has expired — protecting players from impulsive decisions.
Session Time Limits
Configure session alerts that notify you when you have been playing for a set duration. Automatic session timeouts are also available for players who want a hard stop after a defined period of continuous play.
Cooling-Off Period
Take a short break from b399 with a cooling-off period of 24 hours, 7 days, or 30 days. Your account remains intact but no deposits or bets can be placed until the period expires.
