This Game is meant for Cub Scouts.
Decide for yourself if it is appropriate for your younger scouts or not.

2 chairs
2 blindfolds or kerchiefs

The prize goes to the quietest team in this game.
Divide into two teams.
Set up two chairs about seven feet apart, facing each other. These are the sentry posts. One blindfolded scout from each team is a sentry and sits in a chair. The two teams of spies stand at the starting line about 20 feet from the imaginary line between the two chairs.
The leader points to the first scout in line of one of the teams. That scout sneaks between the sentries to the finish line about 20 feet past the sentries. If a sentry hears a spy sneaking by, he points to where he thinks the spy is.

Scoring:

• If a spy makes it to the finish line without being detected, his team gets 2 points.
• If a sentry is first to detect a spy by correctly pointing at him, his team receives 1 point.
• If the spy is on the opposing team, the sentry receives a bonus point.

The leader should not always alternate between the two teams - sometimes point to the same team twice in a row. The sentries should always try to detect a spy because they don't know which team it is from.
