Paper Soccer rules
View gist:12cb9f08bf943101aa69

Paper Soccer

This is a pencil-and-paper version of the game soccer. Two players compete to get the ball into the opposing player's goal, scoring a point. Each point is played on a different field, and there are two fields per page.

The first player with 3 points wins the game.

How to play:

The ball starts at the center of the field (marked by a small circle). For the first point, flip a coin to decide who goes first; for later points, the player who just scored goes second.
