How to test the Chance of Winning?

As previously discussed, casinos can manipulate your winning chances on popular slots — and Leon Casino has decided to lower your odds a lot.

Online casinos do this by changing the "Return to Player" or "RTP". If an RTP is lower, you're less likely to win — and the casino keeps the rest.

We attempt to quantiy this by tracking the same 10 popular game titles at each casino and comparing their RTP settings with the top available RTP for each game.

Have a look at the test results just below. Swipe right to check out how these casinos compare.

As you swipe, you'll quickly see the significant difference between Leon Casino and highest-ranking casinos.

If you're looking for casinos offering the best player odds you’ll find them in our toplist of the highest rated online casinos.

If you don’t know this,You WILL lose:

Almost all slots come with more than one RTP versions.

That means these games may seem like duplicates but one gives you better chances making one a smarter pick to play.

For example Pragmatic Play’s Gates of Olympus. There’s a higher RTP at 96.50% and one that pays back 94.50%.

The difference may seem small but in reality it really matters.

What you should focus on is calculating the casino’s House Edge for the slot.

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 every time you spin (on average) the casino wins 3.50% on the high-RTP version and you lose 5.50% on the bad version.

Using the same math that same $100 buys you 2,857 spins if you’re losing 3.5 cents each versus 1,818 spins when you’re losing 5.5 cents each. That’s an almost 1,000-spin swing between high and low return settings — and a serious edge if you’re trying to win big on Gates of Olympus.
