Jack is the name of a game that is quite popular with children. To play jack, you'll need a small rubber
ball ten small metal objects: jacks. The rules for this game are very simple. To begin, you put the ten jacks on the floor or ground in front of you. Throw the ball up, pick up one jack and then catch the ball. Keep
the jack in your hand and then continue to pick up the other jacks one at a time. You lose your turn if
you do not catch the ball, or if you do not pick up a jack or you drop any jacks from your hands.
When you finish all ten jacks, you now try to do the same thing again but with two jacks at a time. This
is more difficult, of course. You will lose your turn if you do not pick up exactly two jacks or if you make
any of the other mistakes.
