SlotMonster Casino Review

SlotMonster Casino was tested by our casino review team. They used our casino review methodology to look at its strong points and the areas that need work. Our team checked the casino's Terms and Conditions, licenses, player complaints, support, and limits. They used these to find out if this casino is safe and honest or a risk to players.

Our evaluation has led to the casino's Safety Index, a numerical and verbal representation of our findings regarding safety and fairness of online casinos. The greater the Safety Index, the higher the likelihood of playing and receiving your winnings smoothly. SlotMonster Casino scored a substantial shortfall in fairness and safety, as reflected by its Very low Safety Index of 2.6. Proceed with reading our SlotMonster Casino review to learn more about this casino. This will help you make an informed decision about whether this casino is right for you.

Fairness and safety of SlotMonster Casino

In determining a casino's Safety Index, we follow complex methodology that takes into account the variables we have gathered and evaluated in our review. This includes the casino's T&Cs, player complaints, estimated revenues, blacklists, and various other factors.

In our review of SlotMonster Casino, we thoroughly read and reviewed the Terms and Conditions of SlotMonster Casino. We came across some rules or clauses that we did not appreciate, and all in all, we find the T&Cs to be unfair. Unfair or predatory rules have the potential to be held against players to defend withholding their winnings. Therefore, as we discovered some serious issues with fairness of this casino's T&Cs, we advise seeking a casino with fairer T&Cs or at least approaching this casino with caution.

Based upon our estimates and collected information, we consider SlotMonster Casino a big online casino. It has a high amount of restrained payouts in complaints from players, when we take its size into account. When evaluating a casino, we consider the number of complaints in relation to the casino's size, since bigger casinos generally receive a higher number of complaints due to a larger player base.

To our knowledge, SlotMonster Casino is absent from any significant casino blacklists. The presence of a casino on various blacklists, including our own Casino Guru blacklist, is a potential sign of wrongdoing towards customers. Players are encouraged to consider this information when deciding where to play.

All of that, together with other factors considered in our review, has resulted in SlotMonster Casino having a Safety Index of 2.6, which is a Very low value. We strongly recommend players to stay away from this casino and look for one with a higher Safety Index.

T&Cs of SlotMonster Casino evaluated

Whenever we review online casinos, we carefully read each casino's Terms and Conditions and evaluate their fairness. In T&Cs of many of them, we uncover clauses and rules which we consider unfair or outright predatory, as they give the casino the possibility to justify not paying out winnings to players in certain situations.

We found some questionable rules or clauses during our review, because of which we consider the Terms and Conditions of SlotMonster Casino to be unfair.

Note: You can find our specific findings from the T&Cs evaluation here.

SlotMonster Casino player complaints

Our casino assessment rests heavily on player complaints, since they provide us valuable data about the issues experienced by players the and the casinos' way of putting things right. When calculating the Safety Index for each casino, we take into account all of the complaints that we get through our Complaint Resolution Center in addition to the complaints that we find elsewhere.

We currently have 16 complaints about this casino in our database. Because of these complaints, we've given this casino 5,778 black points in total. You can find more information about all of the complaints and black points in the 'Safety Index explained' part of this review.

    Asked this casino through email and chat at several occasions to close my account since the end of December, they kept it open and allowed me to continue deposit until yesterday. Stay far away, including their sistercasinos "Crashino, wsm casino, Rich Gringo, Incognito etc etc. Stay far far away!

    I requested a self-exclusion on Slotmonster.com (EOD Code SRL) due to a gambling addiction, which the operator confirmed and acknowledged. Despite this, I was still able to deposit and gamble after the exclusion was in place — a clear breach of responsible gambling rules and player protection standards.

    When I contacted Slotmonster to request a refund of these deposits, I only received a generic reply stating that wagered funds cannot be refunded, without any serious consideration of their legal and ethical obligation to enforce the self-exclusion.

    I want to make other players aware that Slotmonster does not seem to have effective measures in place to protect vulnerable users or enforce responsible gambling policies. Anyone relying on such protections should be cautious about using this operator.

    If Slotmonster decides to resolve this issue fairly and refund the affected transactions, I am willing to update this review accordingly.

    Warning to everyone! If you have an Outlook server email, for example, they won't receive it. The only email I received was Gmail. The casino's customer service also confirmed this. So if your account isn't closed within a reasonable time, or you don't get any replies to your emails, then this is probably the case. The casino won't do anything about it, even though I have provided proof. Do not use this site under any circumstances!
    • No accountability
    • Very poor customer service, they don't know anything about the casino rules and can't help with problems.
    • Warning to everyone! The casino's customer service email is not working properly, not all emails go through
    • The casino does not follow its own 24-hour rule for closing an account

    After attempting a withdrawal, the transaction remained pending for four days and was then credited back to my account. I then contacted customer service via live chat and complained. As a result, my account was closed.


    This is a clear warning about this casino!!!
    • No withdrawal possible, account has been closed
    • 1 year ago
    Played here for sometime now. Had several wins which were paid out within a few days with no hassle. There used to be connection problems with games but this issue seems to have been rectified.
    • Fast Withdrawals
    • Good game selection
    • good regular bonuses
    • occasionally has issues with game suppliers, one month they are there, the next month such a supplier is missing etc.....
