Jacks

Scatter the jacks loosely on a flat, hard surface.

Toss the ball up with one hand, and before catching it again, scoop up one jack from the ground with the same hand.

Catch the ball after it bounces once (or in the air for a harder version) while keeping the collected jack in your hand.

Repeat, picking up two jacks on the next round, three the round after, increasing the count each round.

A player who fumbles the ball, misses a jack, or knocks other jacks out of position loses their turn.

The first player to successfully complete the highest agreed round (commonly up to "tens") wins.
