About 399b — Bangladesh's Premier Online Casino & Sports Betting Platform
399b was built from the ground up for Bangladesh's gaming community — combining world-class casino games, live cricket betting, and instant BDT payments via bKash and Nagad with a platform that genuinely understands local players.
Who We Are & Why 399b Exists
399b was founded with a single clear purpose: to give Bangladesh's online gaming community a platform that was built specifically for them — not adapted from a generic international template, but designed from the start around how Bangladeshi players actually deposit money, which sports they follow, what games they enjoy, and what kind of support they need. For too long, players across Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, Barisal, Rangpur, Mymensingh, and Cox's Bazar had to work around platforms that treated Bangladesh as an afterthought. 399b was created to change that.
The platform launched with a focus on three core product areas: a live casino powered by Evolution Gaming and Ezugi, a cricket sportsbook covering BPL, IPL, T20 World Cup, and all major ICC tournaments involving the Bangladesh Tigers, and a slots library sourced from Pragmatic Play, NetEnt, Microgaming, Spribe, and Habanero. These three pillars reflect what Bangladesh players consistently said they wanted — access to international-quality live dealer tables, deep cricket betting markets, and a modern slots selection — all in one place, without switching between multiple platforms.
One of the earliest and most important decisions the 399b team made was around payments. Deposit and withdrawal friction is the single biggest source of frustration for Bangladesh-based players on international platforms — currency conversion fees, slow bank transfers, and payment methods that simply do not exist in Bangladesh. 399b resolved this by integrating directly with bKash, Nagad, Rocket, and Upay — the four mobile financial services that Bangladesh players already use every day — alongside Visa and Mastercard for international card holders. All transactions are processed in Bangladeshi Taka (BDT) with no conversion fees applied by 399b on deposits.
Security and trust are non-negotiable at 399b. Every login session, deposit, and personal data exchange on the platform is protected by 256-bit SSL encryption. The platform operates Know Your Customer (KYC) identity verification for all withdrawal requests, protecting members against fraud and ensuring that only the account holder can access funds. Two-factor authentication via OTP is applied on new device logins. These are not optional extras — they are standard features that every 399b member benefits from automatically.
399b is a platform for adults. We are strict about the 21+ age requirement and take responsible gambling seriously. The platform provides deposit limits, loss limits, session time controls, cooling-off periods, and self-exclusion tools that are accessible to every member from within their account settings. We also maintain a 24/7 live chat support team that is familiar with the Bangladesh market, available in English, and trained to assist members who feel their gaming activity may be becoming problematic. Responsible gambling is not a legal checkbox for 399b — it is a genuine commitment to the long-term wellbeing of our community.
Looking ahead, 399b continues to expand its game library, deepen its cricket betting markets — especially around BPL season and Bangladesh Tigers international fixtures — and improve platform performance across all major Bangladesh mobile networks including Grameenphone, Robi, Banglalink, and Teletalk. We are committed to being the most trusted, most complete, and most locally relevant online gaming platform available to Bangladesh players.
Every feature on the 399b platform — from the cashier layout to the live casino lobby — is designed around what makes sense for a Bangladesh-based player, not what is easiest to build.
399b publishes RTP values for every slot title, displays bonus terms clearly in the player dashboard, and never hides fees in small print. What you see is what you get.

399b partners exclusively with internationally recognised studios — Evolution Gaming, Ezugi, Pragmatic Play, NetEnt, Microgaming, Spribe — to guarantee game fairness and quality.
Live chat is available 24 hours a day, 7 days a week including BPL match nights, Eid, and public holidays. The team is familiar with Bangladesh-specific payment and account queries.
Six Reasons Bangladesh Players Choose 399b
From payment methods to game selection to customer support, here is what makes 399b the platform of choice for players across Bangladesh.
399b integrates directly with bKash, Nagad, Rocket, and Upay — the payment methods Bangladesh players already use. Deposits are credited instantly and withdrawals to bKash and Nagad typically complete within a few hours for verified accounts. No conversion fees, no international transfer delays. The minimum deposit and withdrawal are both ৳500.
Cricket is the sport of Bangladesh, and 399b's sportsbook reflects that. BPL, IPL, T20 World Cup, Asia Cup, ICC tournaments, and bilateral series involving the Bangladesh Tigers are all covered with pre-match and live in-play markets. Match winner, top batsman, total runs, and session betting are available with real-time odds updates throughout every match.
The 399b live casino lobby features 150+ tables from Evolution Gaming and Ezugi — two of the most respected live dealer studios in the world. Lightning Roulette, Speed Blackjack, Crazy Time, Dragon Tiger, and Speed Baccarat are live around the clock. Ezugi's Bengali-speaking dealer tables are available during evening peak hours (BST UTC+6) for a genuinely local feel.
The 399b slots library covers everything from classic three-reel fruit machines to Megaways titles and crash games including Aviator by Spribe. Providers include Pragmatic Play, Microgaming, NetEnt, Habanero, and more. All RTP values are published in each game's information panel. The minimum bet starts from ৳20, keeping the section accessible to players of every budget across Bangladesh.
Every session on the 399b platform — from login to deposit to withdrawal — is protected by 256-bit SSL encryption, the same standard used by major banks. OTP two-factor authentication applies on new device logins. KYC identity verification is required before withdrawals are processed. Device activity monitoring flags unusual login patterns and protects accounts from unauthorised access.
399b's live chat support team operates around the clock — including during BPL match nights, Eid, Pohela Boishakh, and all public holidays. The team is familiar with bKash, Nagad, and Rocket payment queries and understands the Bangladesh market. Response times via live chat are typically under five minutes. Email support is also available at [email protected] for non-urgent queries.
The Three Pillars of 399b
399b is built around three product areas that reflect exactly what Bangladesh players want from an online gaming platform.
The 399b sportsbook centres on cricket — BPL, IPL, T20 World Cup, Asia Cup, and Bangladesh Tigers fixtures — with pre-match and in-play markets updated in real time. Football, kabaddi, and hockey are also covered. After login, members can place bets with instant stake confirmation and track results live from the match centre.
150+ live dealer tables from Evolution Gaming and Ezugi span Roulette, Blackjack, Baccarat, Casino Poker, and Game Shows. All tables are streamed in HD from professional studios. Ezugi's Bengali-speaking tables make 399b's live casino genuinely local. Tables are open 24 hours a day, seven days a week, accessible from any device without downloading an app.
Over 200 slot titles and crash games cover every playing style — from ৳20 casual spins on NetEnt classics to high-volatility Pragmatic Play Megaways titles and Spribe's Aviator crash game. All RTP values are published. The slots lobby is organised by category and provider to make browsing the library quick and easy on mobile and desktop alike.
