I don't know. That might depend on the gaming jurisdiction.

>"Colorado gaming authorities say the casino has no legal obligation to pay the $42.9 million. Don Burmania, a spokesman for the division, said the top prize of $251,000 was clearly posted in the casino and that a software malfunction is to blame for the glitch."

Hmm, has anyone seen a picture of the interior of that casino where the maximum payout is "clearly posted"? If it's posted in a EULA-esque fashion, that could be challenged.

Assuming the $43M is wrong, then what's not in doubt is that there was a software error. That, in turn, makes it clear that the machine was not programmed properly to generate its expected payout.

So, not only do we not know how much money was supposed to be paid out in this particular instance, there's no way to know whether any previous punters were ripped off or overpaid. IOW it's a rogue machine.

The gaming commission probably has rules concerning what happens with rogue or malfunctioning machines, but a punter can't be expected to know what they might be.

Ideally, from the POV of the gaming commission and casino operators, they would like to declare any bets placed on a malfunctioning machine to be null and void, so they wouldn't have to pay anything.

In practice, to avoid problems with real or implied contracts, they are probably obliged to pay back any money wagered by that punter during that session, as the machine was clearly not capable of properly handling wagers.

From a PR POV, the punter should probably be awarded a reasonable sum to compensate for her time and anguish. I dunno, maybe 1% of the displayed "win"? < beg >

From the gaming commission POV, incidents like this are bad for business, which will cost the GC money. To discourage problems like this from recurring, I'd be inclined to fine the machine maker and/or casino.
