Two players are enough for this game. They draw a big snail on the ground. Then they have a
 lottery to see who will start first. The first player throws a small stone into the mouth of the
 snail. Next, he tries to push the stone to the center by hopping on his right foot. He hits it with
 the point of his shoe slowly and carefully so that it won't touch the line. At this point, the player
 has a short rest and following the same process, he tries to push the stone back to the mouth of
 the snail. If he manages to do so and also take the stone out of the snail, he gains a point and
 he has the right to try again. But if he steps on the line or his stone touches the line while the
 player is trying to push the stone in and out of the snail, he loses. He also loses if the stone gets
 out of the snail through one of the sides and not through the mouth. The winner is the player
 who gets the number of points set before the game.
