I have seen many casino players, that before playing the first thing they investigate is the RTP offered by the slots,
You found me just reflecting about this point,, I think in addition to a first RTP verification, you should verify it regularly "on the game", (I been experienced) sometimes casinos start forwarding to a different (lower) RTP version without notice and even without making update of the RTP announced on the casino description !
Well, sometimes if the casinos change the RTP constantly, it is something that I do not know if they do it according to what the slot provider recommends, I know that this is something very much theirs, and that a provider says that it is the best for them and when they can be willing to lose, however I have thought that this is an issue that does have a lot to do with the different types of slots, although it sounds a bit strange, I feel that the Pragamatic play style slots I feel that I have more lucky to win, even though I'm not looking to win but to be entertained, but if I've noticed that a lot, in fact some casinos have their apparent RTP in their slots at the bottom.
