How We Test the Chance of Winning

Like we covered above, casinos can lower your odds of winning across their games — but Cosmobet decided to keep your chances of winning high.

They could lower your odds by adjusting something called the "Return to Player" or "RTP". The lower the RTP, you're less likely to win — and the more the casino keeps.

Our testing checks this by checking the same 10 top games at each casino and checking their RTP settings against the best RTP versions of those same titles.

You can view the detailed results we’ve listed below. Slide right to find out how other online casinos stack up.

Visit Cosmobet Slide to compare

If you look through the slides, you can tell that Cosmobet ranks among the top casinos in our review. You've got a few other great options, however we feel happy Cosmobet is a solid casino if what you want is a better chance of winning.

While playing slots the assigned RTP is the key element that makes the biggest difference on your chances of winning.

If you're trying to find opportunities to increase your chances of winning when gambling online choosing a casino with high return-to-player can make a difference. Cosmobet is among the best we’ve tested, and there are more great options in our list of the best casinos online.

How Much Higher is Your Chance of Winning?

The majority of popular slots come in a handful of RTP versions. Take this as an example, a version of Gates of Olympus has 96.50% RTP but another one offering 94.50% RTP.

The games appear exactly the same yet they pay out differently on average.

Every casino can choose if they want to go with a version where players win more instead of a version of the slot with worse RTP.

Some online casinos choose the high-rtp version to make it easier for players to win so they'll continue playing.

However, a lot of casinos offer the worse versions because they hope you'll lose as much and as fast as possible.

If you're trying to win while gambling on onlines slots make sure you play at one of the online casinos listed as "High Chance of Winning" in our toplists. Picking the right online casino to gamble on slots can make a big difference on how much you win!

Our bonus tests covered everything from no-deposit offers to first-deposit matches at every site. We based our first deposit bonus checks on $100, since max eligible deposits vary from casino to casino.
