How We Test the Chance of Winning

As previously discussed, casinos are allowed to adjust the frequency you win on popular slots — and MasonSlots has lowered your odds a lot.

They can do this by altering something called the return-to-player or RTP. If an RTP is lower, your odds of winning drop — and the casino keeps more.

Our testing checks this by reviewing the same 10 popular games at each online casino and comparing their RTP settings with the top available RTP for each game.

You can check out at the results right here. Slide right to find out how the others fared.
