I’ve given 3 star rating because of this time around trying to withdraw, I’ve won 1000 euros in the past and it was processed in relatively quick last time around and paid out. This time trying to withdraw 4000 euros has been a nightmare. * I will come back and give more stars once I receive the payment.

They're the biggest SCAM casino online! All their 5 stars are fake reviews. If you read closely you'll see. They have scammed me an alot of other people which you can see if you continue to read. They promise to pay out when we give them all our bank/ID information then they ignore us. This is a ID Scamming casino and please someone that knows a lawyer or is one get this shut down! They are taking peoples ID and nothing is happening with them. There is tons of proof. DO NOT PLAY HERE!

Scam site they try every trick in the book to kick you out of games when you’re doing good or take providers off the site for only you’re doing well ,They over charge on transactions then take off atleast 10/20% on your winnings lol and the wins are literally low low you’ll only ever get upto your deposit amount, trust me you will always lose on scam monster. Anyone on gamstop do yourself a favour and stay away from them all.

BE WARNED ALL EXISTING AND POTENTIAL NEW SLOTMONSTER CUSTOMERS!!! Slotmonster have effectively stolen all of my legitimate winnings and available funds from my account and I’m absolutely devastated by it. The situation as a whole has been an absolutely horrible experience for me as a customer and the way it’s been handled is just unbelievable. Nothing at all has been said or done about it. The stress they have caused me has greatly affected my mental health and wellbeing, however I can not and will not allow them to get away with this at all. I have no other explanation for why I haven’t been able to access my account since 27/01/25 nor have I been offered a single possibility from their customer support department. I basically classify this as tangible fraud and I’m in contact with my lawyers to bring a case against if and once proved. I’m also contacting my financial institution to recall all of my lifetime deposits made to the casino (which by the way exceeds the total amount which I’m actually contesting), using my many months of correspondence with them without getting answers, responses and being completely ignored as concrete proof that something untoward has happened with my account, I’m not being told what exactly and nothing seems to be being done to rectify the situation. After months of correspondence without any resolution or updates from them, they have conveniently stopped answering my emails completely. I reported to them on 27/01/25 that there seemed to be some issue with my account. Using my credentials to login in as I would always, I was confused as to why my account was showing as being associated with a different email address to mine and another person’s name. No betting history or transaction history of mine was visible. None of my many withdrawal receipts or available balance. Infact there was no other information whatsoever and so clearly proved it wasn’t my account. I’ve been a loyal customer of slotmonster’s for over a year, making many deposits totalling thousands of euro’s and racking up hours upon hours of gameplay. Where had this information suddenly vanished too? This was only a day after making my withdrawal request of €2985 and leaving over €700 of available credit in the casino. For months now throughout corresponding I’ve been completely compliant and as helpful in assisting with their investigations as I possibly could. I’ve sent across screenshots which were requested of the account once logged in to prove the information being shown on the account was that of a different person to me. I also sent across requested documents of my mobile phone ownership to prove my phone number belonged to me. Every time I’ve been asked to cooperate with them I have in a timely manner. Strangely every single time I’ve made correspondence, I’ve noted a regular pattern of getting no response whatsoever and then I have to chase them up always. This was the case when I was asked to send in my mobile phone ownership document. I sent it in on 22/03/25 and still to date I’ve had no reply. Since my last correspondence asking for an update which was on 12/04/25 and many emails in between, I’ve gotten not one. Their silence is deafening which is difficult not to hear loud and clear. I’ve had enough of this merry go round, back and forth, I will be ensuring I inform as much people as I possibly can about the unknown risks they face as a potential customer of Slotmonster. I’ve will be subsequently be uploading to this review a complete and full history of my correspondence with customer support since 27/01/25 to serve as factual evidence and total transparency. TBC…… **** A quick update to note. I have messaged Slotmonster via email today in a last ditch attempt to get a reply with the aim of gaining some understanding and clarity regarding what’s happened with my account. I want to give them a fair opportunity to respond to me. I have however, been ignored for some weeks now and so hold out no hope that I will receive a reply. Pending whether I do or not, I will be posting the complete conversation I’ve had with customer support since the first day I raised this issue on 27/01/25 to back up my claims and hopefully by then I may just receive a response!! I’ve explained to my bank already the current situation and have kept them updated throughout. I’ve sent across to them all necessary correspondence and it should not take too long for me to receive a refund of all my lifetime deposits using the cover of my banking institution’s chargeback procedure, citing internet fraud and pending a criminal report obtaining a reference number.
