This Game is meant for Cub Scouts.

Scouts sit in a semi-circle line facing in.
Number off each scout around the circle.
Start a rhythm of slap knees, clap hands, snap fingers - slap, clap, snap, slap, clap, snap, ...
Scout #1 starts and on the 'snap' of the rhythm, he calls out a number.
The scout with the called number calls out another number on the next 'snap' of the rhythm.
If a scout fails to call a number on his turn, or calls a non-existent number, or calls the number before or after the 'snap', goes to the end of the line and gets assigned the highest number. All other scouts move up to fill in his old spot and move up a number.
The object is to reach the #1 spot and stay there to be the champion Slap, Clap, Snapper.

Make it more difficult by requiring that the previous number called can not be called on the next turn. So, you could not call 3, 5, 3.
