Best of all, 456b's wagering requirements are well below the industry average. So you'll never face the frustration of earning a bonus but being unable to withdraw — that simply doesn't happen at 456b.

Make the required minimum deposit via bKash, Nagad, or Rocket, and the bonus will be credited to your account automatically.
Use your bonus balance to bet or play games. Once the specified wagering requirement is met, the bonus converts to your main balance.
Once the conditions are met, withdraw your winnings directly to your mobile wallet.
Promotions make a real difference in online betting — a good bonus can smooth out your entire experience. 456b understands this well, which is why we offer deals that actually deliver value.
The welcome bonus is 456b's most popular offer. New members receive up to 100% on their first deposit — meaning if you deposit 1,000 BDT, your balance becomes 2,000 BDT. Kick off your betting journey with this bonus.
Many players don't realise that at 456b, you get a portion of your losses back every day. This daily cashback system is hugely popular among bettors in Bangladesh. After midnight, cashback is credited to your account automatically — no application needed.
Existing members matter just as much as new ones at 456b. A reload bonus of up to 50% is available on your second deposit every week — active from Monday morning through Sunday night.
A free bet lets you place a wager without risking your own money. 456b runs free bet offers from time to time — especially during cricket season and major football tournaments. Any winnings from a free bet go straight into your account.
456b runs special festive promotions for Eid ul-Fitr, Eid ul-Adha, Pohela Boishakh, and Victory Day. Bonuses during these periods are significantly higher than usual. Keep your notifications on so you never miss an offer.
