Well the machine was malfunctioning, if it's in the casino's benefit the player doesn't know and the casino wins. If it's in the players benefit the casino has it checked out and the casino still wins. Don't get me wrong, I'm in the camp of you are retarded to go to a casino because they always win but there should be some level of fairness when shit is broken. I don't see them trying to give money back to anyone that their broken machine took, even if it is just pennies.
What you want is apparently not possible. There is already a government body that has rules that they enforce. The government body is apparently ineffective in your eyes. The options are pretty simple. Either dump more resources into a governing body that is failing, or accept that they will always have the upper hand. Unless you had regulators at every machine, then you will have a situation where a malfunction will be a benefit to the house. Its the law as well, where a malfunction cannot be considered a jackpot. In this case, the hands of the casino are tied in terms of not giving her the jackpot of 42 mill, not that they would want to anyway.
