399days is more than a gaming website — it's the go-to destination for millions of people across Bangladesh. From the thrill of cricket matches to the fun of slots, everything is under one roof, fully secure and transparent.
When online gaming first began to take hold in Bangladesh, most platforms were foreign-built and paid little attention to the language, payment methods, or culture of Bangladeshi users. 399days was created to fill exactly that gap.
It started with a small team, a limited budget, and one clear goal — to build a world-class platform for the people of Bangladesh, in their own language, with their own payment methods, and true to their own culture. Today, 399days is the realization of that vision.
Today, 399days offers everything from cricket and football to slots and Live Casino — all in one place. Mobile banking deposits and withdrawals, live support in Bengali, and a dedicated mobile app make 399days a complete gaming ecosystem built for Bangladesh.
The team believes entertainment should be responsible. That's why the platform includes a full suite of responsible gaming features — deposit limits, self-exclusion, and awareness messaging. 399days believes a happy, safe player is the best long-term member.
Planning began for a locally tailored gaming platform built specifically for Bangladeshi users.
399days launched with cricket and football betting. Over a thousand members joined within the first month.
With the launch of Live Casino and slots games, membership grew rapidly. Mobile banking payments were integrated.
Android and iOS apps launched. Live chat support in Bengali goes live — taking the user experience to a whole new level.
399days is now one of Bangladesh's most trusted gaming platforms — and our community keeps growing.

Before trusting any online platform with your money, it's only right to verify its credibility — that's a fair question to ask. 399days makes no compromises on this.
First, 399days operates under a license from an international gaming regulatory authority. Obtaining this license requires meeting strict financial and operational standards. You can verify the platform's license details at any time.
Second, all games are audited by independent third parties. This means there is no way to manipulate game outcomes. RNG certification ensures that the result of every spin or bet is completely random and fair.
Third, member funds are held in a separate account — never mixed with the company's operational funds. This means your money is protected under any circumstances.
Every deposit and withdrawal is processed through encrypted channels.
All games run on certified RNG — no one controls the outcome.
Bonus terms, fees, and rules are always communicated clearly and upfront.
If you run into an issue, you'll get a response in Bangla within 5 minutes — day or night.
399days believes gaming should be a form of entertainment — not a source of income. We always encourage playing within limits and keep responsible gaming features available to all members.
