By looking into the casino's licenses, Terms and Conditions, up-to-date player complaints, limits, customer support, and other various essential elements, our review team has identified the safety and fairness of the casino, evaluating whether it falls into the category of being safe and legit or damaging for players.
Based on their findings, we have calculated the casino's Safety Index, which is our score describing the safety and fairness of online casinos. The higher the Safety Index, the greater the assurance of playing and receiving winnings without problems. Winstler.io Casino has a Very low Safety Index of 1.1, which means it ranks very low in terms of fairness and safety according to our methodology. Proceed with reading our Winstler.io Casino review to learn more about this casino. This will help you make an informed decision about whether this casino is right for you.
Is Winstler.io Casino fair and safe? Safety Index explained
To determine a casino's Safety Index, we use a detailed formula that considers a multitude of information gathered and assessed during our comprehensive review process. These include the casino's T&Cs, complaints from players, estimated revenues, blacklists, and many others.
In our review of Winstler.io Casino, we read and assessed Terms and Conditions of Winstler.io Casino in-depth. To our knowledge, there are no rules or clauses that could be considered unfair or predatory. This is a great sign, as any such rules could potentially be used against players to justify not paying out winnings to them.
According to our approximate calculation or collected information, Winstler.io Casino is an average-sized online casino. This casino has a very high value of denied payouts in player complaints with respect to its size. We factor in a correlation between casino's size and player complaints, because we realize that larger casinos typically tend to receive more complaints on account of increased player count.
As far as we know, no relevant casino blacklists include Winstler.io Casino. Casino blacklists, such as our own Casino Guru blacklist, may indicate mistreatment of customers by a casino. Therefore, we recommend players consider these lists when selecting a casino to play at.
All in all, when combined with other factors that come into play in our review, Winstler.io Casino has landed a Very low Safety Index of 1.1. We highly encourage players to avoid this casino and seek out one with a higher Safety Index.

Absolutely disgraceful casino. Withdrawals take forever. I won 2942 Euros with Bonus Money and they then confiscated all of this money even though I played through the whole 45 times wager requirement of the bonus. They then re-instated 100 Euros on my account, closed my account and haven't yet paid out another withdrawal for 304 Euros as well as not having returned the 100 Euros sat on my account. Absolute fraudsters. Do not play at this casino. You will have a deeply miserable experience. I booked a holiday with my 2942 Euros winnings only to then be emailed and told the whole balance had been confiscated. Disgraceful unethical, immoral business.
Still awaiting my €288.00 withdrawal approaching 4 weeks Since I first tried-took a week to verify my account back and forth with every document humanly possibly,eventually got past that point had a week back and forth with IBAN numbers and so on and so Forth ,was told it had been deposited and had reached my bank ,asked for proof of deposit to show my bank umpteen times kept getting delayed and fobbed off,eventually sent me a picture of something anyone could type on there own computer with basically all the details I had given them ie name ,bank etc hardly proof of deposit no reference number or anything relating to a payment !! Please people do not use this "online casino" even when f you win you can’t get your winnings,it’s nothing but a scam -currently exploring avenues to retrieve these funds ,such a small amount but these fuckers take your money quick enough it’s about the principle now-any suggestions or advice on what authorities to go too to get this place shut down are welcome!

Beware of fraud!!! This casino has fake slots!! In Gates of Olympus, despite scatters, there are also multipliers in the base game. This is not the case with the original.
No player protection. No live chat.
The license is then certainly not genuine.
Achtung Betrug!!! Dieses Casino besitzt gefälschte Slots!! Bei Gates of Olympus kommen trotz Scatter auch Multiplikatoren im Base Game. Das ist beim Original nicht der Fall.
They won’t pay you if you win. I know. Didn’t take the bonuses but when I won big they delayed payments and still haven’t paid me. It’s been 21 days. I’ve stuck to the terms of the withdrawal process
