Why do you need to play on slot games that increase RTP while the potential max RTP on this slot games is still the same on the base RTP of other slot games. ~
I'd say, even if the RTP is actually increased and it's a bit higher than the base RTP of other slot games that doesn't mean you going to win much more. Even playing on slots with 99% RTP you can easily lose all your your balance, so be careful about that. Play only with money you can afford to lose. Don't expect making profits on slots with increased RTP.
