Claim
Claiming a bonus on ack444 is completely straightforward — no codes needed, no complicated forms.
Create an account on ack444 using your mobile number or email. If you have a referral code at the time of registration, enter it too — you may receive an extra bonus.
Log in to your account and go to the 'Bonus' menu. Each available offer will have a 'Claim' button next to it — just click it to activate.
For deposit-based bonuses, simply deposit the required minimum amount. The bonus is credited to your bonus balance instantly via bKash or Nagad.
Once you meet the specified rollover requirement for a bonus, the bonus amount is transferred to your main balance and becomes withdrawable. You can track your progress in the bonus history section of your account.
Each bonus has its own rollover requirement and validity period. See the table below for a quick overview:
Rollover calculation: bonus amount × rollover multiplier = total wagering required. For example, a ৳1,000 bonus at 10x requires ৳10,000 in valid bets.
There's one reason ack444's bonus program stands out among online betting platforms in Bangladesh — the terms are actually achievable. Many sites advertise 50x or 100x rollovers that are virtually impossible to clear in practice. ack444 takes a different approach: the welcome bonus carries just a 10x rollover, which can be completed within 7 days through normal play.
Ack444's welcome bonus program is specifically designed to give new members an advantage from day one. Deposit ৳500 and receive an instant ৳500 bonus, giving you ৳1,000 to play with. You can bet with the full balance, and once the rollover is cleared, your winnings are yours to withdraw.
The weekly cashback offer is a major perk for regular players. Had a rough week? ack444 returns a portion of your losses every Sunday — no special code or manual claim required. It's calculated automatically and credited directly to your account. The cashback rollover is just 1x, meaning a single bet makes it withdrawable.
This free bet offer is made especially for cricket fans. ack444 offers free bets on selected matches across the BPL, Test matches, and ICC events. Any winnings from a free bet are entirely yours — and if you lose, it costs you nothing. Check the bonus page at the start of each week to see which matches have free bets available.
The daily login bonus may seem small at first, but logging in 7 days in a row adds up to ৳350 + ৳300 special reward = ৳650 — which is nothing to overlook. No deposit is required to collect this bonus; simply logging in once a day is all it takes.
The referral program can be highly rewarding for anyone who spreads the word about ack444 among friends. Each successful referral earns you ৳500 with no cap — refer 10 people and you could pocket ৳5,000 in bonuses. Your referral link is available in the 'Refer & Earn' section of your account.
The monthly deposit streak bonus works a little differently. It's designed for members who have made ack444 a regular part of their entertainment. Deposit on 10 or more days in a month and earn an extra 5% on your total deposits for that month — an amount that can add up to a surprisingly large sum over time.
A common question many people have is — can you have multiple bonuses active at the same time? On ack444, you can generally keep one deposit bonus and one cashback or free bet active simultaneously. However, two deposit bonuses cannot run at the same time — you need to complete one before claiming the next. Contact support for more details on this.
Not signing up at ack444 right now means you're genuinely missing out. Starting with the welcome bonus alone, you can nearly double your balance in your first week. Add regular reloads, cashback, and free bets on top of that, and the extra value you can earn each month becomes very significant.

Read the Privacy Policy
Ack444's bonus policy is completely transparent — here are the key things you need to know
Opening multiple accounts under the same identity will result in bonus cancellation. One account gives you access to everything — there's no need for more than one.
Every bonus has a set expiry period. Any unused bonus balance is automatically forfeited once the period ends.
Most bonuses require bets placed at minimum odds of 1.50 to count toward the rollover. Any bets placed at lower odds will not be included in the rollover calculation.
Bonus balance cannot be withdrawn directly. Once the rollover requirement is met, it transfers to your main balance and becomes available for withdrawal.
