One player is a spy and other players (detectives) try to find him. The spy marks its hiding place in the spy booklet but does not show it to the others. Then the hourglass is turned and the game can start.
Other players try to find the hiding place of the spy from the board. Three cards are revealed. Those are the tools that the detectives can use. When all three cards are used, new three cards are revealed. They refer to different areas on the board. Are you on this row? Are you on the same space with cars or water? Seekers mark the spaces where the spy is not and try to find the correct space.
Different tools take different time to use (the time in minutes is marked on cards). If the hourglass is turned the seekers get a penalty minute. The spy gets as many points as it takes in minutes for the seekers to find. All players play once as a spy and the winner is the player who gets most points.
