In-depth review

Here is what we found when we reviewed Marathonbet Casino UK. Our experts used our casino review methodology to check what the casino gets right and where it could do more. Every key factor (the casino's Terms and Conditions, licenses, player complaints, support, and limits) was considered by our team. This helped them work out how safe and legit this casino is.

Our findings led us to the casino's Safety Index. This score shows how safe and fair the casino is. A high Safety Index is a good sign that you can play and get your winnings paid out with ease. Marathonbet Casino UK received a Low Safety Index of 3.5 in our review. This reflects a poor showing for fairness and safety. Take a look at our full Marathonbet Casino UK review, which offers useful insights to determine whether this casino suits your requirements and preferences.

Safety Index of Marathonbet Casino UK – Is it fair and safe?

We calculate a casino's Safety Index based on an elaborate formula that takes into consideration a wide range of information that we have collected and assessed in our review. These involve the casino's estimated revenues, complaints from the players, T&Cs, blacklists, and so on.

In our review of Marathonbet Casino UK, we meticulously evaluated and analyzed the Terms and Conditions of Marathonbet Casino UK. To our best understanding, there are no rules or clauses that could be viewed as unfair or exploitative. This is a favorable sign, considering that such rules could potentially be leveraged to deny the players their rightful winnings.

Based on our estimates or gathered data, Marathonbet Casino UK is a medium-sized online casino. In relation to its size, it has a very high value of withheld winnings in complaints from players. We consider both the casino's size and the number of player complaints and how they correlate, seeing as bigger casinos tend to receive more complaints due to the larger number of players.

Based on our findings, no important casino blacklists feature Marathonbet Casino UK. If a casino is included on a blacklist such as our Casino Guru blacklist, this could hint that the casino has committed some kind of misconduct towards its customers. We urge players to keep this in mind when searching for an online casino to play at.

Taking into account all factors in our review, Marathonbet Casino UK has scored a Safety Index of 3.5, representing a Low value. We suggest players to steer clear of this casino and opt for one with a higher Safety Index.

Terms and Conditions of Marathonbet Casino UK

Whenever we review online casinos, we carefully read each casino's Terms and Conditions and evaluate their fairness. Many of them have T&Cs that contain rules and clauses that we view as unfair or plain predatory, since they can be held against players as a basis for withholding their winnings in certain circumstances.

We did not find any unfair or predatory rules in the Terms and Conditions of Marathonbet Casino UK during our review.

Player complaints about Marathonbet Casino UK

Our casino review methodology relies heavily on player complaints, seeing as they give us valuable information about the issues experienced by players and the casinos' way of resolving them. When determining the casino's Safety Index, we consider all complaints received through our Complaint Resolution Center, as well as the complaints submitted through other websites and channels.

We currently have 9 complaints about this casino in our database. Because of these complaints, we've given this casino 13,457 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.

On Casino Guru, users can rate and review online casinos to voice their opinions, feedback, or experience. Based on these, we generate a total user feedback that varies between Terrible and Excellent.

Based on the 5 user reviews of Marathonbet Casino UK in our database, it has a Mixed User feedback score. You can find the reviews in the User reviews part of this page.

Note: It's important to note that user reviews may not always provide an objective reflection of the casino's quality. Instances exist where casinos write fake reviews to boost their user feedback score, while some dissatisfied players leave multiple negative reviews to tarnish the casino's reputation. Our best efforts are put into filtering these out and calculating an objectively accurate user feedback score; nonetheless, we do not include user feedback in our Safety Index calculation.

    I played twice at this casino with a single deposit and made two withdrawals. To my surprise, the withdrawal time was incredibly fast, taking only seconds for the money to land in my account. As for the games and their RTPs, everything worked perfectly, with good payouts on the games. I even thought about increasing the value of my bets, but I preferred to stick to my standard with lower stakes. To sum up, I recommend this casino: great games, quality providers like PG Soft and Pragmatic, and fast withdrawals.
    • withdrawal at lightning speed payment in seconds
    • i don't receive offers in my email
    Marathonbet Casino UK

    Hello, I've never had any problems with this company, but now I've been unable to make a withdrawal by bank transfer for 7 days. They've stopped me by cancelling it, according to them, due to problems with their supplier. I don't know if they'll actually pay me.
    Their response emails are always repetitive and generally there is no prospect of a solution. I don't think they will return.
    • Nothing
    • SLOW WITHDRAWALS
    Marathonbet Casino UK
    Unfortunately, you have repeatedly entered incorrect payment details when withdrawing funds. For this reason you received a refusal from the payment operator. At the moment the withdrawal of funds has been successfully carried out. We wish you always get only positive emotions from playing at Marathonbet Casino!

    I was treated extremely unfairly.
    Before registering, I asked in live chat if it was possible to win back the bonus to the bonus account if the main account burned down, to which they answered - it’s possible.
    And when I noticed that the bet bar was not changing, I asked a question and after that they sent me an item, for a second:
    The DEPOSIT bonus is wagered exclusively from the main account, so what now? What kind of unfair treatment of players, unfair bonus system?
    In many casinos you can win back your bonus account without any problems, even if you have lost your main one.
    If you want to experience this, please register and play :)
    • What advantages can scammers have?
    • Bonus system
    Marathonbet Casino UK
    There are various promotions available at the Marathonbet Casino. In some cases, you can win back the bonus using the bonus balance, and in some cases this is not possible. The Client agrees to all the terms of the promotion and undertakes to familiarize himself with the rules before taking part in the promotion. We apologize for the inconvenience and look forward to your understanding. We wish you to always receive only positive emotions from playing at the Marathonbet Casino.

    After a while without entering this casino I decided to do so. It has a hood, that's what it's called, right? that always diverts you to unclear situations and that in any case, even if you follow them, they cause errors. This leads to the account being blocked and the web chat skipping. After asking me my name and date of birth, they made me enter the date again but with bars. Once done, they asked me the security question about my mother's last name. I always put the same one but... according to them it didn't match. Good. The next question is my address---well it seems that I live in another one that I didn't know, because they claim that that address is not the one I provided. From all this I deduced that they made a copy paste of my answers, which means that if I put something in capital letters, or I put a hyphen on the floor/door or the number of spaces they gave them an error. My response was that if they didn't want me to play, they should tell me, because the next thing they asked me was to send an email to support with documentation etc etc, and that without winning a prize. If I make a withdrawal I have to send the size of the underwear with the same manufacturer's spaces. Out count and so happy. Good afternoon

    • the unfortunate access to the web with capcha
    • The disastrous data verification
    • The ease with which they begin to request documentation by mail without having accessed the website

    The terms and conditions are unfair as they limit the earnings you can get, although this has never been the case for me
    • Fast withdrawals almost always
    • Slots microgaming and Just for the win
    • Sometimes the money is deducted when you deposit but the deposit takes a few minutes to be credited to your account
    • Sometimes withdrawals are delayed
    Marathonbet Casino UK
