Last verified: March 2026 | Operator: LeoVegas Gaming PLC | UKGC Licence: 39198
Opening an account at 21 Casino takes about five minutes. You need to be 18+ and based in the UK. Fill in your details, pick a deposit limit (the UKGC makes this mandatory), confirm your email — and you're in.
Right after signing up, you get 10 free spins on Book of Dead without depositing anything. When you do decide to put money in, the minimum is £10 — debit card, PayPal, Apple Pay or bank transfer all work. That first deposit gets matched at 121%, up to £100 in bonus funds.
We've laid out each step of the process, what info you'll need on hand, and what to expect once your account is live — including the ID checks you'll go through before your first withdrawal.

How to Register — Step by Step
Here's what the registration looks like from start to finish:
Visit 21 Casino
Go to the 21 Casino website and click the "Register" or "Join" button in the top right corner. The registration form opens in a simple overlay.
Enter Your Details
Provide your full name, date of birth, email address, and UK mobile number. Create a secure password. You'll also need to enter your UK postcode and home address.
Set Deposit Limits
You'll need to pick a deposit limit — daily, weekly, or monthly. The UKGC requires every casino to ask for this during signup. You can change it later in your account settings.
Verify Your Email
Check your inbox for a verification email and click the confirmation link to activate your account. Check your spam folder if the email doesn't arrive within a few minutes.
Make Your First Deposit
Deposit a minimum of £10 using any accepted method (debit card, PayPal, Apple Pay, or bank transfer) and your 121% bonus will be credited automatically.
