666 Casino Review

666 Casino launched in 2017 with a bold, devilish theme. It is run by Caddell Limited – the team behind PlayGrand – and licensed in the UK and Malta.

666 Casino is licensed by the UK Gambling Commission and the Malta Gaming Authority. UK players get full UK protections.

New players get a welcome bonus, and a Wednesday reload adds extra value midweek. In our records, wagering was 35x the deposit plus bonus. Current offers are listed on this page.

Loyal real-money players are invited to the VIP club by a personal manager.

The library includes games from NetEnt, Microgaming, Play’n GO, Nolimit City, Push Gaming, Red Tiger, Relax Gaming, Thunderkick and ELK Studios, with live games from Evolution.

Methods include Visa, Mastercard, Skrill, Neteller, Trustly, Paysafecard and bank transfer. In our records there were no maximum withdrawal limits, but withdrawals could take up to seven days.

The site is mobile-friendly.

Live chat is open 24/7.

666 Casino suits UK players who like its theme and want a well-licensed casino with reloads.

Opening an account at 666 Casino takes a few minutes:

1. Click Join or Sign up and enter your email, a password and your personal details.
2. Confirm your address and date of birth – UK casinos must verify that you are 18 or over before you can play.
3. Set your deposit limits during sign-up or in your account settings.
4. Make your first deposit and opt in to the welcome offer if you want it.
5. Upload ID and proof of address if asked. Doing this early speeds up your first withdrawal.

Example: deposit £50 and get £25 bonus. At 35x deposit plus bonus, you need £2,625 of bets.

Offers change regularly, so always check the current terms on the casino site before you deposit.

As a UK-licensed casino, 666 Casino must give you tools to stay in control:

• Deposit limits – daily, weekly or monthly.
• Reality checks – reminders of how long you have been playing.
• Time-outs – a short break from your account.
• Self-exclusion – including GAMSTOP, which blocks you from all UK-licensed sites at once.

If gambling stops being fun, free confidential help is available from the National Gambling Helpline on 0808 8020 133. Read more in our guide to gambling harm.

• PlayGrand – a sister casino from Caddell Limited.
• Mr Green – a polished UK casino.
• Casumo – gamified rewards and a big library.

Our overall score for 666 Casino is 4.7 out of 5. It is based on four areas we check for every casino:

We also look at customer support, mobile play and the fairness of terms. Scores are reviewed when casinos change their offers or services.

Withdrawal times are typical ranges after the casino has approved your request, and can vary with verification and your bank. Prepaid vouchers such as Paysafecard usually cannot be used to withdraw, so you will need another method to cash out. Compare methods in our casino payments guide.

666 Casino is a properly licensed UK casino with a fun theme and reloads. Slow withdrawals and deposit-plus-bonus wagering are the drawbacks.
