A bonus code (or promo code) is a short word or string, like WELCOME100, that tells the casino which offer to give you. Some bonuses are credited automatically; others only work if you enter the right code at the right moment. Here is how they work and how not to lose one.
Why casinos use bonus codes
- Tracking: codes show which website or campaign brought the player.
- Exclusive offers: partner sites sometimes get better deals than the standard bonus.
- Choice: when several welcome offers exist (casino or sports, for example), the code selects one.
Where to enter the code
- At registration: a "promo code" field in the sign-up form.
- At deposit: a field on the cashier page, before confirming the payment.
- In the promotions area: for reload bonuses and free spins.
The golden rule: enter the code before depositing and before playing. Codes added later are often rejected.
Common mistakes
- Typing the code with a space or the wrong case.
- Depositing less than the minimum required for the bonus.
- Using an excluded payment method (some e-wallets are excluded from bonuses).
- Claiming a code for new players on an existing account.
A code doesn't change the terms
A bonus with a code still has wagering, max bet, max cashout and expiry. Read them before you claim, and check the real value with the wagering calculator. To compare offer types, see our welcome bonus guide, no deposit bonus guide and reload vs welcome bonuses.

Frequently asked questions
Where do I enter a casino bonus code?
Usually in the registration form, on the deposit page or in the promotions section of your account. Enter it before you deposit.
What happens if I forget the bonus code?
In most cases the bonus is not credited. Contact support immediately, before playing, and ask if they can add it.
Are casino bonus codes free?
Yes. A real code never costs money; be wary of sites selling codes.
