Marathonbet Casino Review

Our expert team set out to review Marathonbet Casino from all angles. We used our casino review methodology to find out what makes it tick and where it misses the mark. They considered the fairness of the casino's Terms and Conditions, licenses, complaints from existing players, customer support, limits, and other important factors to figure out whether this casino is safe and legit, an outright scam, or somewhere in between.

Our team's review data was used to calculate the casino's Safety Index. This score rates the safety and fairness of online casinos. With a higher Safety Index, your chances of playing and receiving winnings without complications increase. Although Marathonbet Casino scored an Above average Safety Index of 7.4, meaning it is a suitable option for some, keep in mind that there are casinos with better rankings in terms of fairness and safety. Continue reading our Marathonbet Casino review to find out more about this casino and determine if it's the right fit for you.

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

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 Marathonbet Casino, we thoroughly read and reviewed the Terms and Conditions of Marathonbet Casino. We came across some rules or clauses that we did not appreciate, but all in all, we consider the T&Cs to be mostly fair. A rule that is unfair or predatory has the potential to be held against players to defend withholding their winnings, but in the case of this casino, we found only minor issues.

According to our approximate calculation or collected information, Marathonbet Casino is an average-sized online casino. In proportion to its size, it has received complaints with an average total value of disputed winnings. 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.

As far as we know, no relevant casino blacklists include Marathonbet Casino. 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.

In our comprehensive review of all relevant aspects, Marathonbet Casino has attained an Above average Safety Index of 7.4. This casino might be an adequate option for some players, however, keep in mind that there are other casinos that prioritize fair treatment and safety of their customers to a much higher degree.

Our Marathonbet Casino T&Cs review

Whenever we review online casinos, we carefully read each casino's Terms and Conditions and evaluate their fairness. In some casino T&Cs, we find clauses that we regard as unfair. These can give the casino grounds to hold back player winnings in certain cases.

We found some questionable rules or clauses during our review, however, we consider the Terms and Conditions of Marathonbet Casino to be mostly fair.

Note: You can find our specific findings from the T&Cs review by clicking here.

Terms and conditions
Mostly fair
Issues found: 1
Last updatedLast updated
Show detailed analysis

We go over the terms and conditions of each casino and look for unfair rules that could potentially be used against players. Any clauses we consider to be unfair result in a lower Safety Index for the casino.

Bigger casinos are generally safer for players, because their high revenues allow them to pay out even very big wins without any issues and their quality has been proven by a large number of players. We take into account estimated revenues over the last 4 years.

Blacklists

      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
      Thank you for positive feedback. Please note that you can always find offers on our website or in email, specified during registration. We wish you always get only positive emotions from playing at Marathonbet Casino!

      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
      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
      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 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
