The McDonalds Monopoly Fraud (2014)
Somewhat unrelated, but there is a great documentary on Michael Larson; who figured out a software randomness flaw in the game show Press Your Luck, and exploited it live on TV to the tune of $110,000. In that day, $110,000 was an obscene amount of money to win on a gameshow. No game show was awarding even close to that.https://www.youtube.com/watch?v=nzNMCXWCZzQ
