Two teams are formed with an equal number of players. They are two armies ready to fight. A line in the middle separates them, and another line at the back of each army (about fifteen yards [15m] from the centre line) indicates the detention camp for the prisoners of war. The warriors fight by throwing a weapon (the ball) which should be big but light. Whoever has the ball tries to hit a warrior of the opposite camp. When a warrior is touched by the ball, he becomes a prisoner of war and must go in the detention camp of the opposing army. A prisoner can be released and go back to his army if he catches the ball within the detention camp and touches a warrior of the enemy army with it. An army can help its prisoners to escape by sending them the ball over heads of the enemy. The army that makes the most prisoners in a given time wins.
