About 3999db
3999db was founded with a clear mission: to provide the people of Bangladesh with a world-class, trustworthy online gambling experience that respects local culture and payment preferences. From day one, we built our platform around the needs of players in Dhaka, Chittagong, Sylhet, Khulna, and every district in between — people who wanted genuine sports odds, fair casino games, and the ability to move money instantly using bKash and Nagad.
Over six years in operation, 3999db has grown to serve over 2.4 million registered players. We partnered with industry-leading providers — Pragmatic Play, Evolution Gaming, Spribe, Ezugi, NetEnt, and Microgaming — to ensure every game in our library meets global fairness and RTP standards. Our technology team works around the clock to maintain 99.9% uptime and sub-second response times, even during the busiest BPL and IPL match days when traffic spikes dramatically.
We are equally proud of our commitment to responsible gaming. 3999db enforces a strict 21+ age policy, offers self-exclusion tools, and publishes transparent responsible gaming guidelines accessible at any time. Our long-term vision is to be the most trusted name in Bangladeshi online entertainment — a platform our players recommend to friends not just because of the bonuses, but because we always pay out on time and treat every player with respect.
3999db is an internationally licensed platform operating offshore. It is not registered under any Bangladeshi domestic authority, nor does it claim to be.
Bangladesh's primary gambling legislation — the Public Gambling Act of 1867 — predates online betting entirely and does not explicitly address internet-based casino or sports wagering activity. This creates a legal grey area that many Bangladeshi players navigate daily.
Each user is solely responsible for ensuring their own compliance with local laws before registering and playing. We strongly encourage all players to seek independent legal advice if uncertain about their obligations.
This platform enforces a strict 21+ age restriction. Gambling is for adults only. If you feel your gambling is becoming a problem, please visit our Responsible Gaming page for tools and support resources.
❓ Frequently Asked Questions
