As I understand it, the manufacturer of the slot machine is on the hook for any progressive jackpot the machine pays out.
Given that modern day slot machines use a random number generator (and knowing a few things about how RNGs are not quite random enough), is the manufacturer aware of when a particular machine will hit the jackpot?
If the manufacturer is aware, is it because the machine itself notifies them in some fashion or are they aware because they can simply model the results in some simulator?
I recall watching a Travel Channel show about slot machine gambling a few years ago. They mentioned that when somebody wins one of these progressive jackpots that the manufacturer is notified by the machine. They also mentioned that the manufacturer and casino have an agreement where the manufacturer provides the machines for free or a nominal cost in exchange for a cut of the revenue the machine takes in. They also said that the manufacturer pays out the jackpot. During the show, one of the casino managers was interviewed on the floor and he seemed to know (or feel, I'm not sure) that the jackpot was going to be hit very soon. Sometime during the show, I recall the jackpot was paid out. Honestly I don't know if the show was dramatizing the manager's knowledge. Unfortunately, I don't have any references at this time and I'll have to look for them after work.
