Add a twist of mystery and excitement to a classic game of red light, green light.
Have one player, the detective, stand 50 feet or more away from the other players, the fugitives.
To start, she yells "Out of jail" and then turns her back to the fugitives, who begin to advance toward her to steal her badge (a ball, hat, or coat that sits at her feet).
At any moment and without notice, the detective can whirl around and shout "Freeze!" Then, the fugitives must halt completely. Any unlucky fugitive caught moving must sit down where he or she stood and remain in this "jail" for the rest of the game.
The first fugitive to reach and steal the detective's badge becomes detective for the next game.
