Players sit in a circle and start counting round the circle from "one." If the agreed figure for the game is seven, each time the number being called includes the figure seven or is a multiple of seven, the player keeps quiet and clasps his hands together. If anyone makes a mistake the leader records a point against him.

When the boys become good at this game, add one or two other numbers, so they will have to keep very sharp not to get caught with numbers four, six and eight going on at once.

For one number the player clasps hands. For the second number he will put both hands above his head. For the third number he can nod his head. Most players will find thinking of two numbers at once difficult enough.
