How to test the Chance of Winning?
Like we said above, casinos can change your winning chances on almost all slots — and Gratowin has lowered your chances of winning for some games.
They accomplish this by changing what's known as the return-to-player or RTP. With lower RTP, it gets harder for you to win — while the casino makes more.
We attempt to measure this by reviewing the same 10 popular games at each online casino and comparing the RTP of each against the best RTP versions of those same titles.
Have a look at the results just below. Swipe to the right to discover how competing casinos performed.
