It's very rare for players to hit the jackpot on a slot machine. Can a casino make sure they never have to pay that out by having the machines "malfunction" to display a larger-than-maximum amount in those rare cases, and then avoid having to pay out anything close to the maximum, while still retaining all the player losses?
Example stories where the answer seems to be "yes" can be found with Katrina Bookman or Pauline McKee. Both played the slots at casinos that kept the players' losses, until they were notified by slot machine hardware that they'd won >$40M. Then the casinos pointed to signs “Malfunction voids all pays and plays,” and claimed that since the machines were malfunctioning, the casino didn't have to pay more than a couple dollars. The Iowa Supreme Court agreed with the casino in McKee's case and the New York State Gaming Commission agreed with the casino in Bookman's.
In the words of Bookman's lawyer, "the casino used the same broken machine to take money from players, and that everyone who used the machine should at least get their money back...Doesn’t that mean a place can claim a machine is broken every time somebody wins?" That is the question here.
