Scatter the jacks on the ground in front of yourself, and…

• Toss the ball (upward) with the right hand.
• Grab the jack(s) with the right hand, and then rap your right knuckles on the ground, while allowing the ball to bounce.
• Catch the ball with the right hand, while still holding onto the jack(s).
• Transfer the jack(s) to the left hand, while still holding onto the ball with the right.

…And repeat the steps until all jacks are captured.

Start off with Onesies and continue on with Twosies, Threesies, Foursies, etc.; all the way up to Tensies.

A seasoned jacks player would rap her knuckles at the same instant the ball bounced.
