Oops so I was wrong, that means the places I have seen use the same shared jackpot, but the ones you show are only sharing casino jackpot. That makes sense, in a way, if a casino is able to only pay out based on their own players, but then I wonder who the bank is in this case, is it the provider or the casino?
I always assumed slots had the bankroll and then paid out to the casinos just commission. Because every time there is issue with big wins the casino seems to be contacting the provider for payment or this is how I remember whenever I'm reading.
I guess casinos are contacting them to be sure that nothing wrong has happened and the big win is not due to a bug or any kind of cheating from the player. But AFAIK, the bankroll for payouts usually belong to the casino, games being just some kind of online softwares. For progressive jackpots like Mega Moolah shared with all players I guess it's different, the casinos send a commission to the provider to fuel the jackpot.
I play that slot too. It has a larger gauge required to be filled in able to enter the bonus round but it leaves a wild on identical 4 tile which the normal moon princess game doesn’t have. This slot has high RTP because it keeps giving small win but I rarely made a significant win even with playing in long run. I guess this slot is perfect for competition. I will try to use this on next tournament just to make sure I have enough time to farm. Please give me an update if you will manage to secure spot at the end of the tournament.
I have checked the RTP indicated in the rules of the 4 versions available at Livecasino and it seems that
Moon Princess has the higher one : 96.5%, while
Moon Princess 100,
Moon Princess Trinity and
Moon Princess Christmas Kingdom for unknown reasons have a RTP a little bit lower : 96.2%. These values are consistent with the RTPs mentioned by the casino though.
