How We Test the Chance of Winning

As we mentioned above, casinos are allowed to manipulate your chances of winning across their games — but Duelbits has chosen to give its players the best chance of winning.

They could lower your odds by changing what's known as the "return-to-player" (RTP). If an RTP is lower, your odds of winning get worse — and the casino profits more.

We test this by reviewing the same 10 popular games at each online casino and comparing their return-to-player settings with the top available RTP for each game.

Review the detailed results listed below. Swipe to view how all the other online casinos performed.
