How We Test the Chance of Winning

As mentioned above online casinos have the power to change your odds of winning on many of the most popular slots — and most choose to lower your odds.

Casinos do it by modifying the “Return to Player” (RTP). If an RTP is lower, it gets harder for you to win — while the casino makes more.

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

Have a look at the full results listed below. Swipe to explore how all the other online casinos fared.
