Take a ball and find a street with raised curbs. Stand opposite of each other, one on each side of the street. When it is your turn try to throw the ball exactly on the edge of the sidewalk opposite of you. If the ball rolls back, bounces or flies, you score a point and you can throw again, if not, it is the other player’s turn. The game is played until one of the players has reached the number of points that were agreed upon.
