Offers not re-verified
As of October 2026, we cannot confirm the offers below, because Mostbet's main site is not available from our location. They were last confirmed in January 2026 and may have changed.
Mostbet Casino First Deposit Bonus
For new accounts at Mostbet online casino, the welcome casino bonus for the first deposit is +125% up to 35,000 BDT + 250 Free Spins.
The bonus adds extra money and free spins to your first deposit, which helps new players get used to the casino games faster.
How to Claim Mostbet Bonus?
You can claim the bonus when you register on the website, the mobile site or in the app. The rules are the same on every device. Registration bonuses are only for players who have never had a Mostbet account; regular players can use the loyalty program, promo codes and deposit rewards instead. To get the welcome bonus:
- Visit Mostbet's website and select the Registration tab on the main page;
- Choose a sign-up method in the window that appears. Fill in your email and phone number, and choose a password and account currency;
- Select the welcome casino bonus;
- Agree to Mostbet's terms and conditions, confirm that you are over 18, and complete the registration;
- Log in to your personal account;
- Make a deposit with a payment method of your choice. The bonus is not activated without a deposit.
The welcome bonus is then added to your account. Follow the wagering rules so you can later withdraw it with your winnings.
How to Use Mostbet Bonus?
The casino bonus can be used across the casino section: slots, live dealers, live games, table games and virtual sports. Check Mostbet's current terms for the minimum first deposit and for the deposit needed to activate the 250 free spins. The casino wagering period is 72 hours. The Mostbet bonus guide gives the casino wagering requirement as both x40 and x60, so check the current terms before you claim. If you do not meet the requirements, the bonus cannot be credited to your main account. You must also pass verification before winnings and bonuses can be withdrawn.
