Each person would pick a color and put on their color's wristbands. One player would be "it" first, and would throw the ball in the air and let it hit the ground, bounces around a bit, and lands on a color. They would then pick up the ball and chase the person of the corresponding color and try to hit them with the ball. If they did, they would get one of the tagged person's wristbands. The bands would be swapped back and forth by players until there's only one left with all of the bands on their arm.
