A bonus code unlocks a specific offer when you enter it at sign-up or in the cashier. At many new casinos the welcome offer needs no code at all; where one is needed, the casino shows it with the offer.
A code does not change the rules: a coded offer at a UK-licensed casino is capped at 10 times wagering like any other.

Short answer
Do I need a bonus code at a new casino?
Usually not. Most UK welcome offers are applied when you opt in at registration or at your first deposit. Where a code is needed, enter it exactly as shown before you pay; a code added after the deposit is often refused.

In depth
Where codes come from
Casinos issue codes for launch offers, partner promotions and returning customers. Only use codes from the casino itself or a site you trust, and read the terms they unlock. Our guide on ways to get no deposit bonus codes covers the common sources.
Codes and marketing consent
Many reload codes arrive by email or text. UK-licensed casinos must ask for your consent before sending marketing, and you can withdraw it at any time in your account settings.
Questions
Bonus codes: questions
Where do I enter a bonus code?
In the registration form or the cashier, before you confirm the deposit.
What if I forget to enter the code?
Contact support straight away. Some casinos add the offer manually; many do not.
Do bonus codes give better offers?
Sometimes. A code can unlock a partner offer, but the 10x wagering cap still applies.
Are codes from forums safe to use?
Only if the casino confirms the offer. Expired or fake codes are common.
Responsible gaming
Play only if you are 18+ and it stays fun
These rules apply on every page of this site. A young casino has less history to judge it by, so the limits matter more.
18+ only
Adults only, everywhere
You must be 18 or older. A licensed casino must check your age and identity before you can deposit or play, so have your ID ready when you register.
