Players have to match two different phone "senses" to the same location.
Players are divided into two groups of "senses". The game leader assigns each player locations to be kept secretive. The visual "sense" group is sent out to take photos of their assigned locations. When they return, the auditory "sense" is sent out to take audio recordings of the locations.
The the players present their captures and the challenge is to make the attempt to match the sound with the sight of a location.
Each group of "senses" goes out into the field at different controlled times.
Photographs must be taken no more than 24 inches from an object or part of the location.
