How to Sign Up at 666 Casino
Last verified: 11 March 2026 by Charlotte Hughes
Signing up at 666 Casino is fairly painless, though you will need to go through KYC verification before you can withdraw. I've walked through the whole process so you know exactly what to expect.
666 Casino is operated by AG Communications Limited (part of Aspire Global) and holds UKGC licence 39483. The registration takes about 3 minutes, and if your documents are in order, verification can be done within a few hours.
What You Need to Sign Up
Before you start, make sure you've got these ready. Nothing worse than getting halfway through and realising you need to dig out your passport.
Personal Details
- Full legal name
- Date of birth (must be 18+)
- Email address
- UK mobile number
KYC Documents
- Photo ID (passport or driving licence)
- Proof of address (utility bill or bank statement)
- Documents must be less than 3 months old
- Clear photos, no glare or cropping
Important: Your name and address on your account must match your ID and proof of address exactly. If they don't match, verification will fail and you'll need to contact support to sort it out.
Step-by-Step Registration
Visit 666 Casino
Head to the 666 Casino website and hit the green "Join" button in the top right corner. You'll see it straight away — it's the most prominent thing on the page. You can also sign up through the mobile app if you've already downloaded it.
Enter Your Personal Details
Fill in your first name, surname, date of birth, and email address. Create a password — make it strong, at least 8 characters with a mix of letters, numbers, and symbols. You must be 18 or older to register.
Use your real details here. Fake information will cause problems later when you try to verify your account and withdraw.
Provide Your Address
Enter your full UK residential address. This needs to match your proof of address document, so use whatever appears on your bank statement or utility bill. If you've recently moved, you'll need a document showing your current address.
Set Your Deposit Limits
This is a UKGC requirement and honestly a good idea regardless. You'll choose a daily, weekly, or monthly deposit limit. Pick something sensible that you're comfortable with.
Decreasing your limit takes effect immediately. Increasing it has a 24-hour cooling-off period, which is there to stop impulsive decisions.
Verify Your Identity (KYC)
Upload your photo ID — either a passport or UK driving licence. Then upload proof of address: a bank statement or utility bill from the last 3 months.
Tips for smooth verification:
- Make sure the photo is clear and well-lit
- All four corners of the document should be visible
- No glare or shadows covering important text
- Documents must not be expired
Make Your First Deposit
The minimum deposit is £10, but you'll need £20 to qualify for the welcome bonus. Choose from the available payment methods:
Credit cards and cryptocurrency are not accepted for UK players.
Claiming Your Welcome Bonus
Once you're signed up and verified, you've got two welcome bonus options to choose from. I'd personally lean towards Option A if you prefer low-risk, since those spins are wager-free.
20 Wager-Free Spins
- Deposit & wager £20
- On The Goonies Quest for Treasure 2
- Get 20 wager-free spins
- Winnings are yours to keep
100% up to £66
- 100% match on your first deposit

KYC Verification Explained
KYC stands for "Know Your Customer" and it's a legal requirement under UKGC regulations. Every licensed UK casino has to do this — it's not optional and it's not 666 Casino being difficult.
The process involves confirming your identity and address. Most of the time, if your documents are clear and match your account details, it's processed within a few hours. Occasionally it can take up to 72 hours.
Accepted Photo ID
- UK passport (in date)
- UK driving licence (full or provisional)
- National ID card (not accepted for UK)
- Expired documents
Accepted Proof of Address
- Bank statement (last 3 months)
- Utility bill (last 3 months)
- Mobile phone bills
- Documents older than 3 months
Top tip: Take photos of your documents in good natural light, on a dark background. Make sure all text is readable and no corners are cut off. This is the number one reason verification gets delayed.
Common Sign-Up Issues
"Your account couldn't be created"
This usually means there's already an account with your email address or details. Try the login page instead, or use the forgotten password feature. If you genuinely haven't registered before, contact support.
"Verification failed"
Double-check that your documents are clear, not expired, and that the name and address match what you entered during registration. If the issue persists, reach out to 666 Casino's support team via live chat.
"I can't deposit"
Make sure you're using a debit card, not a credit card — credit card gambling is banned in the UK. Also check your bank hasn't blocked gambling transactions. Some banks require you to enable gambling payments in your app. See our payments page for more on accepted methods.
"I'm under 18"
You cannot register. UK gambling law requires all players to be 18 or older. This is verified through KYC checks. Attempting to use fake details is a criminal offence.
