NOT for sale

Independence and honesty above all

We believe our reviews need to be independent if we are to help everybody who comes to our site to choose the best online casino for themselves.

That's why they are not influenced by anything other than the best judgement, knowledge and analytical skills of our casino review team.

Our story and history

We have learned a lot about how online gambling works, right down to the most technical levels, and then we decided to share our knowledge with the world.

Frequently asked questions for casinos

How is the Safety Index calculated?

Our formula used for Safety Index calculation is quite complex and includes many relevant factors, with the two most important being each casino’s size and justified player complaints that we discover during the review process. We consider these in proportion to each other, as it’s natural that bigger casinos tend to have more complaints because of the higher number of players, and this is how we get the basis for our Safety Index.

But that’s not all. We also check other factors, mostly focusing on things we consider problematic, such as unfair clauses in Terms and Conditions and many others. Check out our fair gambling codex to get to know our opinion about what casinos should and shouldn’t do.

How can we get a higher Safety Index from you? Can we buy it?

Our Safety Index is a result of a complex review process which considers tens of factors and, very importantly, it is not for sale. We are not willing to jeopardize our own reputation and our independent ratings by accepting money from any casino.

You can, however, influence the rating by treating players well and removing any unfair clauses from your Terms and Conditions. Growing in size can help too, as the size of each casino is one of the factors included in our Safety Index calculation.

If you are not sure why we’ve rated your casino badly, feel free to ask us for an explanation. We are ready to give you the reasoning behind our rating, which can help you figure out how to get a higher Safety Index and also become a better online casino during the process.

How can we get a better position in your casino list? Can we buy it?

The positions of individual casinos in our lists of casinos are based on a number of factors, with the most important being each casino’s Safety Index, our visitors’ countries of residence and their language preferences.

You can’t just buy a better position. We are never willing to give a bad casino a better position, placing it higher than another casino, which we consider to be a better fit for players from a certain country.

However, the situation is a bit different at the top of the list, especially in countries with multiple great casinos, which we consider to be on the same level. If we are indifferent about which casino gets displayed on a higher position, we are willing to give a better position to the casino that offers us better affiliate conditions.

We don’t like your review of our online casino. Can you change or delete it?

We don’t change nor delete our ratings just because the casinos don’t like them. Our aim is not to serve casinos. We want to serve players and help them choose good online casinos.

If you are not sure about why your casino got a low Safety Index from us, feel free to contact us. We will explain it to you. Also, contact us if you find any incorrect information in our review. Let us know and we will check it out and correct it if the information actually is incorrect.

Why can’t we see our brand on your website?

We have more than 5000 casinos in our database. These are sorted differently for each user, depending on their country and language preferences. If you can’t see your casino in our list of casinos, try searching for it using the search button in the upper right corner.

If this doesn’t help, it’s likely that your online casino is not in our database yet. Contact us and we’ll guide you through the process of adding it to our website.

Do you use e-mail marketing?

We only send e-mails to visitors who have subscribed to our newsletter, based on the types of updates they've chosen to receive from us.

We have a new bonus promotion for this month. Can you add it to your website?

We don’t promote short-term temporary bonuses on our website, because keeping them up-to-date would be an incredibly difficult task to do, with the number of casinos we have in our database. We will happily add your long-term bonuses, though.

Frequently asked questions for players

What does the Safety Index mean?

The main idea about our Safety Index is to evaluate how casinos treated players in the past (based on player complaints) and whether they paid out legitimate winnings to them. We also consider the size of each casino and find out whether they do anything which we consider to be unfair towards players, such as having unfair clauses in Terms and Conditions.

All of this helps us recommend casinos which treat players fairly and pay out winnings to them.

The size of each casino is a very important factor. Small casinos have the Safety Index capped, because we are not sure about their to pay out very big wins. For example, a win of $200,000 that doesn’t come from a progressive jackpot might be a problem for some small casinos. That’s why only very big casinos with a small number of justified complaints can get a Very high Safety Index (9+ out of 10) from us. That being said, all casinos with a Safety Index higher than 8 can be considered safe to play at, with a chance of not getting paid out after a legitimate win being very close to zero.

Why are some casinos with a High Safety Index listed higher than casinos with a Very high Safety Index?

Our Safety Index is mostly about the probability of players getting their winnings paid out. It doesn’t tell much about other things, such user experience or game selection, which are undoubtedly also very important.

Because we consider all casinos with a Very high or High Safety Index to be fair and very unlikely to withhold legitimate winnings, we also use other criteria to sort the individual casinos in our lists, not just the Safety Index.
