Registering on Mostbet in 2027 takes under two minutes — but one step makes a significant difference to your welcome bonus. Entering promo code MOST888 in the registration form raises your first-deposit match from 100% to 125%, up to $400. This guide covers how to register correctly, where to find the promo code field, and how to make the most of the bonus once it's credited.
What Does MOST888 Unlock at Registration?
Sports: 125% bonus on first deposit, capped at $400. Wager 5× on accumulators (3+ legs at odds ≥ 1.40) within 30 days.
Casino: 125% bonus on first deposit up to $400, plus 250 free spins spread over four deposits. Wager 35× on eligible slots.
Without MOST888, the standard offer is 100%. On a $200 deposit that's a $50 difference — worth taking 10 seconds to enter the code correctly.
Registration Process — Step by Step
Open the Mostbet website or app and tap Register.
Choose registration method: phone number, email address, or social account (Google, Facebook).
Complete the personal details form: name, date of birth, currency, country.
Locate the Promo Code field — it appears near the bottom of the registration form, just above the final confirmation button on most interfaces.
Type MOST888 exactly. The field is case-insensitive for most regions but enter it in capitals to be safe.
Select your preferred welcome bonus: Sports or Casino. This choice is permanent — it cannot be switched after registration.
Accept the terms and complete registration.
Verify your account (SMS or email).
Make your first deposit from $1. Bonus is credited automatically within minutes.

Registration FAQ
Can I change my bonus choice after registering?
No. The Sports/Casino selection at registration is permanent. Choose carefully before confirming.
What if the promo code field is not visible?
Scroll down in the registration form — it's usually below the currency selector. On some mobile browsers, it may require scrolling. Try the desktop version or the official app if it still doesn't appear.
Does registration cost anything?
No. Creating a Mostbet account and entering a promo code are both free.
Can I register multiple accounts to use the code more than once?
No. Mostbet enforces one account per person and per household. Multiple accounts result in bonus forfeiture and account closure.
