Marbles self explanatory.
Use small stones or similar.
To begin the game, each player tosses all five knucklebones in the air and tries to catch as many as possible. Each player then repeats the procedure using the knucklebones that he or she caught the first time. The score each player obtains in this way determines the order of turns during the game.
In the most common variation on this game, the first player throws all of his knucklebones on the ground. He picks one up, which becomes known as the jack. He tosses the jack into the air, picks up another bone from the ground, and catches the jack as it falls. He transfers the picked-up bone to his free hand and throws the jack again. This procedure is repeated until the player has picked up all of the knucklebones. If a player drops a bone, misses the jack, or moves a bone inadvertently, he is out and the next player takes his turn. When a player succeeds at picking up and holding all the bones during one turn of play, he goes on to try to pick up all the bones at one time. When the player has picked up all the bones in this way, he then tries to pick up bones in groups of first three and then four.
