During registration (recommended)
The form has a dedicated promo code field. This is the safest route: the account is tied to the promotion immediately, with nothing left to remember.
Mostbet promo code
Mostbet issues several coupons through the year, but only one applies to the welcome package. This is the current one:
Mostbet promo code 2026
125% up to $300 plus 250 free spins. New accounts only, one use per person.
The code is free and does not alter your deposit conditions. It simply registers the account as a participant in the extended promotion. Without it, a new account receives the smaller standard package.
What the code unlocks
| Code | MOSTBONS150 |
| Casino bonus | 125% up to $300 + 250 free spins |
| Sports bonus | 125% on the first deposit |
| Deposit window for 125% | 30 minutes from registration |
| Fallback rate | 100% within 7 days |
| Eligibility | New accounts, 18+ |
| Uses | One per person |
| Cost | Free |
When you activate it you choose a direction: casino, which is where the 250 free spins sit, or sports betting. Both cannot run at once.
Where to enter the code
⚠️
After registration
Under Promotions → Bonuses, in the coupon field. This only works while the account is still unfunded — once you deposit, the welcome code stops applying.
Using the code in two minutes
Copy the code
Use the button above — it copies MOSTBONS150 without typos.
Have your payment ready
The 30-minute window starts the moment you register, not when you finish the form.
Open registration
Choose phone, email, social network or one-click sign-up.
Select your currency
Pick your local currency — it cannot be changed afterwards.
Paste the code
In capitals, with no leading or trailing spaces.
Deposit and pick a track
Casino or sports. The bonus credits automatically once the deposit confirms.
Terms attached to the code
| Condition | Value |
|---|---|
| Maximum bonus | $300 |
| Free spins | 250, credited in batches |
| Casino wagering | 60x, typically 72 hours |
| Sports wagering | 5x, 3+ legs at 1.40 or higher |
| Deposit window | 30 minutes for 125%, 7 days for 100% |
| Verification | Required before the first withdrawal |
One bonus at a time. Cancelling an active bonus forfeits both the bonus and any winnings from it. Full conditions are on the bonuses page.
What the code is actually worth
The 125% applies to your deposit amount. Here is how the playable balance builds up:
| Your deposit | 125% bonus | Playable balance | Free spins |
|---|---|---|---|
| $20 | $25 | $45 | 250 |
| $100 | $125 | $225 | 250 |
| $240 | $300 | $540 | 250 |
| $400 | $300 (capped) | $700 | 250 |
Past $240 the bonus stops growing because it hits the $300 ceiling. Depositing more purely for the bonus adds nothing.
If the code does not work
| Symptom | Cause | Fix |
|---|---|---|
| "Invalid code" | Stray space or lower case | Type it manually in capitals |
| No promo field visible | One-click registration | Add it under Promotions before depositing |
| Bonus not credited | Deposit below the minimum | Check the amount, then contact live chat |
| Only 100% credited | Deposited after 30 minutes | Expected behaviour — the enhanced rate expired |
| "Already used" | Duplicate account or shared IP | One account per person; open a support ticket |
Other coupons
The welcome code is single-use, but the account keeps receiving offers afterwards. The official Telegram channel distributes periodic reload codes, and the loyalty programme converts accumulated coins into spins and cash. The full list lives on the bonuses page.
- Weekly cashback — up to 10% of casino losses, no code needed.
- 100 free spins — for installing the app and depositing from it.
- Birthday gift — for verified accounts over 30 days old.
- Referral commission — on the activity of friends who sign up with your link.
Promo code FAQ
What is the Mostbet promo code?
The current code is MOSTBONS150. It unlocks the extended welcome package: 125% on the first deposit up to $300 plus 250 free spins.
Where do I enter the promo code?
In the promo code field on the registration form. It can also be added afterwards under Promotions → Bonuses, but only before the first deposit.
Does the promo code expire?
The code itself has no published expiry, but the bonus does: the deposit must land within 30 minutes for 125%, or within 7 days for the standard 100%.
Can I use it on an existing account?
No. The welcome code works on new accounts only, once per person, IP address and payment method.
Does the code cost anything?
No. It is free and does not change your deposit terms — it simply flags the account as part of the extended promotion.
The code is not working. What now?
Check that it is typed in capitals with no spaces, that the account is new, and that your deposit meets the minimum. If all three are fine, contact live chat with the transaction ID.
