----------------------

This game is very popular in countries all around the 
world. Some children use plastic Jacks or small metal 
Jacks or they use the knuckle bones from a leg of lamb 
and call the game knuckles.
  1. You sit in a circle. Decide who will go first and then in what order you will have your turns.
  2. The first player puts the 5 Jacks in one hand and then DUMPS them in a little pile in front of them.
  3. Move one Jack away without disturbing the other Jacks in the pile.
  4. Now throw this Jack into the air and pick up the other 4 Jacks in one go and catch the one that went up in the air as well.
  5. If you miss the next player gets a turn. The game of Dumps continues until one player is the winner.
Modern

Same as above except instead of picking a jack up and throwing it in the air, you have a rubber ball which you bounce then attempt to sweep up all the jacks before catching the ball. Can only be played on hard surfaces.
