How We Test the Chance of Winning

Like we said above, casinos can manipulate the frequency you win on many popular slots — and Leon has decided to lower your odds a lot.

Casinos do it by updating something called the “Return to Player” (RTP). The lower the Return to Player. the lower your odds of winning — and the casino's cut grows.

Our testing checks this by testing the exact same 10 slots at every online casino and seeing how their RTP compares to the highest return possible for each game.

Visit Leon Slide to compare

When you swipe through, you’ll notice the gap between Leon and the top casinos.

While playing slots the configured RTP setting is the factor that can have the biggest impact on your chance of winning.

If you want to spend money at casinos offering you the best odds you can easily find them in this list of today's top online casinos.

If you don’t know this, You WILL lose:

Most online slots have several RTP settings.

Basically each version might look exactly the same but one gives you better chances making one a smarter pick to play.

Take the slot Gates of Olympus. There’s one with a 96.50% return and also one that pays back 94.50%.

That small gap might not seem important but it counts more than you think.

What you should focus on is checking the House Edge of the casino.

The House Edge is: 100 % – 96.50 % = 3.50 % for the good version. And: 100 % – 94.50 % = 5.50 % for the bad version.

This means that across the aggregate of bets the house keeps 3.50% in the high-RTP version while 5.50% is taken in the worse one.

If you run the numbers a $100 bankroll equals roughly 2,857 spins on the high RTP setting however just 1,818 spins in the worse RTP version. That’s a difference of nearly 1,000 spins if you pick the better version — which is a massive difference if you’re chasing wins on Gates of Olympus.

Leon - All Test Results

Compilation of all casino tests and calculations for rankings.

Bonus and Promotions Test.

We counted both no-deposit bonuses and first-deposit deals when testing each online casino. Since max eligible deposits differ by site, we measured first deposit bonuses using a $100 baseline.

Below are Leon's bonus and promotion test results.
