If there’s zero expectation of winning millions on a a slot pull, then you shouldn’t be surprised when a jackpot of millions gets revoked.  She probably should get the max jackpot though, which is what her attorney argued. 

If you make slot machines then don’t fucking allow them to malfunction in a way that displays million dollar payouts.  That is bullshit.  It’s not hard to say in the code if the payout number is out of bounds it should show an error rather than a large number.

Edit: if you think that there is no way to make slot machines reliable enough to never display an erroneous multi million dollar false jackpot win, you are sorely mistaken.  It’s literally just about how good the design of the product is, how good of engineers designed and built and coded it.

Edit2: wow, never anticipated so many people would be vehemently on the side of the slipshod company who made a machine that is capable of faulting in this way, while practically screaming “THERES NOTHING THAT CAN BE DONE” …  the engineering on this machine was shoddy IN THIS MACHINE here guys, it could’ve been a lot better and we shouldn’t feel bad about expecting better.

Cosmic rays can cause these malfunctions in any computer operated device.  There is literally no way to stop cosmic rays from coming in from the universe and bitflipping binary code.
