Here's an interesting story that someone's going to make a movie about. Two guys found a glitch in a Video Poker machine — the kind you find in casinos. It enabled them to "win" hundreds of thousands of dollars…and then Las Vegas came after them.
There's kind of a Catch 22 about winning money in Nevada: You get to keep the money as long as it's "a game of chance" but if you figure out a method that moves the odds in your favor, the casino can say, "That's not a game of chance" and prosecute you. This is the principle on which they prosecute those who count cards at Blackjack, which is something I used to do. I did not give it up for fear of being beaten up and/or arrested. I wasn't winning or playing at that level. But I sure understand the temptation.
