Or boxes for this game. At each turn, $100 is placed at random in one of three boxes. Contestants try to guess the box with the $100 in it, and get to keep the money if they find it. When one of the contestants has won $400, that contestant goes on to try for the grand prize of an auto. Both get to keep any money they have found.
Here is how it is played:
In each of rounds 1-3, Player A tries one box. If he fails, B tries one of the remaining two boxes. If he fails, A opens the last box and gets the $100. Then $100 is loaded randomly in a box for the next round.
Rounds 4, and 5-7 if necessary, are played the same, but with B going first each round.
