From what aspect do you see that? more people are winning maxwin?. If you use this method, the slot is being played by most people is gonna win (which is the gate of olympus). As you know, these slot are the most played on pragmatic play.
I don't think, there has such things as (max-win percentage) and I believe the chance or code are the same only have different theme
I compared the two slot games Gates of Heaven vs Gates of Olympus, in stake.com we can check who reached maxwin + the date so we can conclude, but the conclusion is not final because Stake.com only detects maxwin with regular spins while the buy feature is not included, it only counts x50. In general I agree it is the same slot game with a different theme however when Stake.com claims a higher RPT it means there will be risks if the information is fake we certainly know the impact, it's just that we don't know how to prove it. By the way thanks @mu_enrico
