Firefly is a tagging game that explores temporal memory, and exploits the balance of collaboration and competition. The game is designed to be played in the dark. Players, wearing flashing LED badges, compete to see who can steal the most badges from other players. The winner is the person with the most badges at the end of the round.
The key component of Firefly is that player can only steal a badge when the light is OFF. This is where the exploration of temporal memory comes into play. The players can track each other while their badges are lit up but must find and steal a badge when it goes dark. The challenge is to continue to track players after the light is gone. It is this tracking that is using the same memory skills we have for remembering where we parked our car.
