Two to six players participate, one is designated as the leader.

The leader secretly jots down any number from one to 100 on a strip of paper.
Others take turns guessing the number's value.

If the mystery number is greater than a guessed number, the leader raises his or her arms.
If it is less than the guessed number, the leader squats down.

As the children use the leader's clues to solve the mystery number, their guesses become more and more educated.

When the number is identified, another child becomes the leader.
