This Game is meant for Boy Scouts, Bear scouts, Webelos scouts.

Improve deduction skills

Each patrol goes to a separate area as far away from the other patrols as possible to prevent accidental eavesdropping.
Each patrol leader comes to the game leader and is told the name of the famous person for this round.
Each patrol leader goes to a patrol other than his own and the patrol asks him Yes-No questions to figure out who he is.
The first patrol to yell out the correct name wins 1 point. The patrol of the scout answering the questions for that team also receives 1 point. After a number of rounds, the patrol with the most points wins.

Alternative: As a single team, work together in trying to guess the identities as quickly as possible.
