From welcome bonuses to weekly cashback, 40i has a dedicated offer for every type of player.
Bonuses at online betting and casino sites can be confusing. How much can you actually get, what's genuine value, and what's buried in conditions — these are questions worth asking. 40iAt -, we've made transparency a priority from day one. Every bonus comes with terms written in plain language, wagering requirements are reasonable, and the bonus funds are genuinely usable.
Whether you're on the streets of Dhaka or by the port in Chattogram, the first thing you'll notice when you open 40i on your smartphone is the sheer variety of our bonus offers. A welcome bonus for new members, reload bonuses for regular players, weekly cashback deals, and exclusive rewards for VIP members — 40i's bonus program truly covers everything.

Go to the 40i registration page and create a new account in just 30 seconds using your mobile number or email. The interface is fully in Bangla, so the process is straightforward.
Log in and head to the Promotions section, then select the bonus offer you want. The welcome bonus is applied automatically for new members.
Make a minimum deposit via bKash, Nagad, or Rocket and your bonus will be credited to your account as soon as the payment is confirmed.
Play your favorite games with your bonus. Once the wagering requirement is met, your winnings will be added directly to your balance and can be withdrawn at any time.
Wagering requirements can be confusing, but here's the simple version: if you receive a ৳1,000 bonus and the wagering is 10x, you'll need to place a total of ৳10,000 in bets. Those bets can come from your real balance, your bonus balance, or a mix of both.
40i-'s wagering requirements are significantly lower than other sites in Bangladesh. Most bonuses here carry wagering between 5x and 15x — very achievable. A few bets on a cricket match can often be enough to clear the requirement.
The cashback bonus is one of 40i's most popular offers — and for good reason. There's no wagering requirement; it goes straight to your balance and you can withdraw it whenever you like. If luck isn't on your side during the week, at least Friday morning brings a little relief.
Sports Betting fans, here's something worth knowing. Bets placed on cricket, football, or kabaddi all count toward your wagering requirement. That makes 40i's sports bonuses genuinely easy and enjoyable to use.
A new reload bonus goes live every Monday at midnight.
