666casino Reviews 

Not even 1 star they are a rinser. Playing since mid 2025 never winning. Love playing immortal romance after getting to gold level problem with site set you right back to beginning. Played Big catch then rinsing rtp really bad then tried book of the dead hot slot more like hot not they rinse you dont waste your time at least other sites give you a chance. Pure rinsing site never using again blocked my account with them and any of there other rinsing sister sites

Think I spoke to soon when leaving a good review for this site.
Now trying to withdraw they requested a bank statement, which improvided. They said it’s not acceptable because it doesn’t display iban number. My account is just a pockit account and I downloaded the statement via the app.
To be honest its sites like this that do me a favour because playing is not worth the stress, I really don’t feel like gambling any more.

Really bad site, do not use. Played £300 on a popular slot and didnt hit a bonus at all. It lasted under an hour and, even though there are numerous bonus games, never hit one. This is not a casino, its a scam site. It was so bad, I self excluded to ensure I dont use again.

This site is terrible now no bonuses ever land your just waiting and waiting then money gone in minutes. Im not playing on this site again. So id rather just have my account closed.

Shifty site, stay clear!

3weeks now I haven't still been paid. I made an complaint and no updates on that either, I keep getting the same reply saying please wait it's with the finance team since the 8th. How long does it really take them just to withdraw some money!!! This is ridiculous DO NOT PLAY HERE

Please peopel dont play on this website, they are just taking your money … lost a lot money 🙁🫤 i want my refund this website is fake . Please dont play . Someone need inform uk gambling this website is a fake .

Deposited £20 with a promotion deposit bonus of 100% upto £66. Never got the £20 added. Been trying to contact customer care all day with no one getting back to me. Shocking way to treat new customers. Probably would have deposited again as the game all seems ok, but I am not paying my hard earned cash to a company that obviously doesn't look after its customer. PITY!! UPDATE Been in contact with live chat and the goal posts have changed. It is now deposit and wager £20 to received 20 wager free spins on goonies Quest for Treasure 2. Last week it was Grace Media that I reported to ASA through the gambling commission and now it looks like it is going to be this lot also.

If it could be rated lower it would be, small wins but theirs a catch when you start building up the game will throw an error can’t play multiple games please close this resets what you have in so it then goes on the take the win % is small on all if you ask them they are rather rude with % information wasn’t always like this at one point in time used to be a decent casino

Disgusting gameplay awful service does not play right and extremly dodgy site and gameplay does not land nothing at all .no returns whatsoever on your play . Extremly suspicious spin outs consistently . The reels spin out so fast theres no way they will land and when they go to land the third bonus its magically spins out everytime .odd bonus lands but pays very minimal amounts hardly no collectors land on the bonuses so you get very minimal pay. Most of the time they constantly spin out .Definately needs investigating extremly dodgy on every game every single play .

total bottom of the employees .this casino

They self exclude me when I didn't want that to happen and I got my winnings pending they don't listen to customers

Apsalutly horrible company,do not give them any money!

Worst site to waste your money on. Deposited over £200 and never got one single bonus on any game I played on. Total scam. Played one game for 28 minutes on 40p spins and still didn't get a single bonus AVOID

I’ve won money on here before around 500-600 and the money was in my bank within a few hours but now I’ve won 10 times that amount they are making it an obstacle to get my earnings Into my bank. They told me it will be in my bank in 48 hours, after the 48 hours their now asking for a lot of documents which I find very concerning, I do trust that they will do the right thing and give the money they owe me so fingers crossed they pay up and maybe in the future they can fix things and become a top 10 casino in the world, they just need to be more transparent and have quicker withdrawals.

hi i was playing now im kicked off and the whole website wont load but every other website will is the website down or what’s happening

The worst!! Stay away!

Appalling casino. 24/7 help isn’t available ever and they don’t respond when using the contact us email system. Accepted a deposit and let me play a bonus then refuse to let me place any bets saying limit reached. They now have my money and want me to cancel my bonus winnings to withdraw my money. Absolute scam of a site. Avoid and use more legitimate sites. Also give bonuses which don’t work then refuse to issue them saying it’s not policy to issue bonuses your unable to use

I am waiting on a withdrawal of £30,000 (plus the £5 admin fee that I had to pay!!!) since last Wednesday afternoon. Yes, thirty thousand. Can I get a meaningful update anywhere? Nope. Live chat giving me the runaround. No straight answers. I have uploaded all of my documents and these have all been approved so I’ve done my part. So frustrating not being able to talk to anyone and there is one agent that disconnects when he can’t be bothered to answer your questions anymore. Disgusting treatment. PAY ME MY FAIRLY-WON WINNINGS PLEASE. Site says 0-6 days for payout AFTER cash out is approved - mine is still pending after all this time

They refusing pay winigs keep promises escalate they laying to people!!!people don't play on this site don't waist your money!!!
