Built in Bangladesh, for Bangladesh.
Three Dhaka-based founders. One mission: give Bangladeshi players world-class odds, bKash-fast payouts, and a platform that actually speaks Bangla. Five years later — 500,000+ players and ৳2 billion+ paid out.

A platform built on trust & fairness.
4SIX was founded in 2021 by three friends from Dhaka — a fintech engineer, a cricket analyst, and a UX designer — who were tired of the same complaint: Bangladeshi players got the worst odds, the slowest payouts, and the least respect on every betting platform they used.
The first beta shipped with 12 cricket markets, bKash-only deposits, and a promise: every payout, every question, every bug answered in Bangla — from day one. That promise still defines every decision the team makes five years on.
Today we serve 500,000+ active players across Bangladesh with 300+ sports, 2,000+ casino games, and the tightest odds margins in the market. Every feature we ship is judged against a single question: does this make the platform better for a player in Sylhet or Chattogram who just wants their winnings in bKash before the next over starts?
Five years, one mission.

About 4SIX — Bangladesh's most trusted betting platform
4SIX is an online sports and casino platform built in Dhaka, serving 500,000+ Bangladeshi players, operated under a Curaçao eGaming license. We launched in 2021 with a single commitment: faster payouts, fairer odds, and a product that actually speaks the language of the players using it.
Who we are
The founding team is three people — a fintech engineer with eight years at mobile-money providers, a cricket analyst who worked in commentary booths for BPL and IPL, and a product designer who shipped consumer apps used by millions across South Asia. We started because no platform we used treated Bangladeshi players like a primary audience; every tool was a translation of a Russian or Filipino product, with bKash bolted on as an afterthought.
What makes us different
Three things, measurable and verifiable:
- bKash/Nagad payouts in under 2 minutes. Industry average in BD is 4–12 hours. Our infrastructure is built directly against real-time mobile-money APIs — not batch-settled once an hour.
- Higher odds, lower margins. Cricket margins sit at 1.5–2% versus 6–10% at most competitors. That's a structural difference — you keep more when you win.
- Bangla-first, not Bangla-translated. Our UI, support, and marketing are written in Bangla first, then translated to English. Every VIP manager speaks Bangla. The difference shows up everywhere.
How the business works
We earn the house edge on casino games (published RTPs, averaging 96.4%) and the sportsbook margin on sports bets (1.5–2% on cricket, 2–3% on major football). We do not take a cut of player deposits, do not charge withdrawal fees, and do not share player data with third parties outside of mandatory compliance reporting. All of this is verifiable in our Terms of Service.
Our approach to responsible gaming
Betting is entertainment. It should never be a source of stress, hidden debt, or relationship damage. 4SIX ships deposit limits, session timers, cool-off periods, and full self-exclusion as default settings — not buried under three menus. We partner with BeGambleAware and GamCare, and our self-exclusion list is honoured across the entire operator group. If you're worried about your play, the Responsible Gaming page has direct links to Bangladeshi helplines and our own cool-off tools.
Our compliance posture
4SIX operates under Curaçao eGaming license #8048/JAZ2021-008 through Antillephone N.V. This requires mandatory KYC for transactions above ৳50,000/month, AML monitoring, fraud prevention, and periodic audits. All RNG games are tested by iTech Labs; live dealer games by GLI. Player funds sit in segregated bank accounts reconciled quarterly. We run an active bug-bounty program with independent security researchers and publish a quarterly transparency report on reported incidents.
Where we're headed
2026 brings native Android and iOS apps, physical support offices in Chattogram and Sylhet, and a regulated Bangla-language sportsbook feed built in-house. We're also investing in responsible-gaming tools — a real-time spending dashboard, AI-driven burnout detection, and one-tap cool-off — because a platform that looks after its players lasts longer than one that optimizes for engagement.
