In the outer door of the city, twenty people compete in a game of pick-up. The first person to pick up a random number of balls wins the game. The person who wins the most games wins the right to play in the next round of games. The winner of the first round gets to choose the first ball in the second round. If he wins the first game, he gets to play the second game, and the person who gets the most wins the third game. In the third round, the winner gets to pick the fourth ball. The loser gets the fifth ball.
