Jacks

To teach people everywhere how to play Jacks! (And to see how far I can travel!)

A small purse with a game of Jacks inside it!
Jacks - The Play
To decide who starts, a player throws five jacks into the air with one hand and tries to catch as many as possible on the back of the same hand. The jacks that were caught are then thrown up again from the back of the hand where they came to rest and as many as possible are caught in the palm of the same hand. The other players do the same and the player who catches the most jacks starts, play continuing in a clockwise fashion.
The first player prepares to start by throwing the five jacks on the ground and then picking up the ball.
The player throws the ball up, picks up one jack with the same hand and then catches the ball before it hits the ground. The jack is then put into the other hand. This is repeated until all the jacks have been picked up. The player then throws the jacks back on the floor and starts again, but this time, two jacks must be picked up each time except for the third and final throw when, obviously, only one jack is picked up. Once this is achieved successfully, the player starts again but this time with three jacks and then again with four jacks and finally the ball is thrown up and all five jacks are picked up at once before the ball is caught.
When the player misses the ball or does not manage to pick up the requisite number of jacks, the turn immediately finishes and the next player has a try. The player who manages to progress furthest in the sequence of throws wins.
Variations
Some people allow the ball to bounce one before it must be caught. This should make the game a little easier.
Experts can experiment by continuing the play in the form of harder challenges. For instance, the ball might be bounced downwards instead of thrown upwards or a clap of the hands must be performed before the pick-up or perhaps the other hand must be used as a second round.
