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.

MasonSlots - Bonus, Promos, and Free Spins

1 out of 5 stars

We measured first deposit bonuses at all major online casinos to identify the best return on your deposit.

We use Theoretical Bonus Value (TBV) to measure the average return on a first deposit after completing wagering, from minimum to maximum permitted deposits.

Here’s the summary for MasonSlots.

MasonSlots - All Test Results

Compilation of all casino tests and calculations for rankings.

Bonus and Promotions Test.

We measured casino promos by including both no-deposit perks and initial deposit bonuses. We chose a $100 baseline for first deposits as casinos have different maximums for bonus eligibility.
