Claim your promotion bonus in just a few simple steps
Create a free account at 5666bef. All you need is your mobile number and a password.
Log in with your registered details. Bonus offers will be displayed to you on your very first login.
Go to the Promotions page, pick the offer you want, and click the "Claim" button.
Make a deposit via Mobile Banking, Nagad, or another available method. If you have a promo code, make sure to enter it.
Once your deposit is confirmed, the bonus is added to your balance instantly. Start playing and win.
Every bonus comes with a wagering requirement — meaning you need to place bets totalling a set multiple of the bonus amount before you can withdraw. This is typically 3–5 times the bonus.
Every promotion has a set expiry date. Use your bonus before it expires, or it will be forfeited automatically.
Any attempt to open multiple accounts to claim bonuses will result in all accounts being closed. Play fair and enjoy the benefits.

Many players have questions about how the 5666bef promotion system works. New members in particular often wonder which bonus is the best fit for them. That's why we've covered every offer in detail here.
The first deposit bonus at 5666bef is a great opportunity for new members. Deposit BDT 500 and your account gets credited with an extra BDT 500 bonus — giving you BDT 1,000 to start with. It's essentially a risk-free advantage, letting you play with bonus funds before touching your own money.
Keep in mind, this bonus is available for the first deposit only. So deposit as soon as possible after registering and make the most of it.
5666bef knows that loyal members are its most valued players. That's why there's an attractive reload bonus every week for members who make deposits — Silver members get 5%, Gold members get 10%, and Diamond members get up to 15%.
This bonus is added to your account automatically every week — no separate claim needed. Just keep playing and keep earning rewards.
Everyone knows you can't win every time in online gaming. But at 5666bef, a losing week doesn't mean walking away empty-handed. Every Monday, a portion of your net losses from the previous week is returned to you as cashback.
This cashback is credited directly to your main wallet — not your bonus balance. That means you can use it to play or withdraw right away. It's one of the most popular offers at 5666bef.
The 5666bef referral program is simple. You get a unique referral code. When a friend registers using that code and makes their first deposit, you receive a BDT 200 bonus and your friend gets a BDT 100 welcome bonus. It's a win for both of you.
The more friends you refer, the more you earn. There's no cap — refer as many people as you like.
