From the Welcome Bonus to Eid Special offers — a04 brings something different for every bettor. See all active promotions below in one place.
Online betting platforms often advertise big bonus numbers that rarely match what players actually receive. The terms and conditions are usually so complex that most users have no idea how to use their bonus. a04 knows this problem well — which is why every promotion's terms are written in clear, straightforward language.
Promotions at a04 go well beyond a one-time bonus for new players. Regular bettors can enjoy reload bonuses, special offers during cricket season, and exclusive packages around Eid and Puja. There's always something new each week — and that's exactly what makes a04 the go-to choice for bettors in Bangladesh.
What stands out most about a04's promotions is that they're genuinely achievable. The wagering requirements aren't impossible to meet. Take the welcome bonus, for example — it comes with just a 5x wagering requirement, meaning a ৳500 bonus only needs ৳2,500 in bets before it's withdrawable. That's well ahead of the industry standard.

Activating any promotion on a04 takes just a few simple steps.
Sign up for free on a04. Just enter your mobile number, name, and password — your account will be ready in 2–3 minutes.
Head to the promotions page and select the offer you want. Read each offer's terms and conditions carefully to avoid any confusion later.
Deposit via bKash, Nagad, or Rocket. If a promo code applies at the time of deposit, enter it then. Most offers don't require a code.
The bonus will be credited to your bonus balance instantly upon deposit. You can withdraw once the wagering requirement is met.
Welcome bonuses have become standard on online betting platforms in Bangladesh — but a04's is a little different, not just in size but in terms too. A 100% match on your first deposit means if you deposit BDT 1,000, your account will have a total of BDT 2,000 to play with.
A 5x wagering requirement means you need to place bets totalling five times your bonus amount before you can withdraw it. For example, if you receive a BDT 1,000 bonus, you'll need to wager BDT 5,000 to convert it to cash. This is a realistic condition that most active bettors can clear within 1–2 weeks.
Keep in mind — not all bet types count toward bonus wagering. For Sports Betting, only bets with minimum odds of 1.5 will contribute to the wagering requirement. That's a fair threshold, since most regular bets already fall above it.
The weekly reload bonus activates every Monday. Deposit at the start of the week to claim your bonus and make your betting throughout the week even more rewarding.
During festivals and special events, a04 runs limited-time offers. Keep notifications on so you never miss a deal.
Refer your friends and contacts. Earn BDT 300 for every successful referral — refer 10 people and you'll pocket a total of BDT 3,000 in bonuses, hassle-free.
No separate opt-in is needed for the daily cashback. Lose any bet and you'll automatically get 5% back.
