No because even at Sportsbet the jackpots of these games are different. They are progressive jackpots, they work in the same way as progressive jackpots of physical slots, meaning their value increases till one user wins them. I know there are progressive jackpots shared with all the users of the slot playing at whatever casino, like Mega Moolah for example, but those ones, and all Play'n Go progressive jackpot slots I guess, are only shared between the users of the same casino usually.
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.
