The Wall, based on the television show of the same name, is played with two teams, with each team trying to earn more money than the other by game's end. One player on the team drops balls into different channels of the wall, with the balls ending up in troughs that are worth varying amounts of money. This player's partner attempts to answer trivia questions, without seeing how much money the ball-dropper has earned. After eleven questions, the player behind the wall has to decide whether to accept the guaranteed amount or to take a chance that the sum won through questions is higher.
