FlagJack is an augmented reality mobile video game built explicitly for the iOS platform. The game pits two teams against each other in a fight to capture the opponent's flag and return it to home base. Using the iOS device's screen as a heads-up display, virtual information is visually presented to the user: a player is alerted when nearing the enemy's flag, when approaching an enemy team member, and perhaps most importantly, when their own flag is stolen!

FlagJack is perfect for an urban environment and games of all sizes, from two to ten players per team. This modern twist on the classic game of capture the flag allows for new strategies for defending a flag, and exciting instances of attacking the enemy's flag – if you can slip by the enemy's iOS-device-radar!
