Here's one "in reverse":
Back on ABC LMAD, there was a game where two contestants tried to guess the price of an item, and whoever was closer won money; the amounts were 100, 200, 300, and 400, and if either contestant got 700, they won a car. The problem is, if one player gets both of the first two, then the third one becomes, "It doesn't matter what the first player does, but if the first player wins, they can screw the second player out of the car."
