Hunt is an augmented reality game. Players enter the game by downloading it onto their mobile, where it runs in the background all of the time.
Whenever the player goes into a public place such as a shopping centre or park, they become "in-play". They can also enter the "in-play" state by requesting a quarry at any time and the server will assign a geographically proximous quarry for them to hunt. A player will often be quarry and hunter at the same time.
In order for the player to claim a frag, they must locate their designated quarry in the public space and aim their mobile's camera at the other player. On the screen the quarry's unique icon will appear over the other player. Once the hunter snapshots the icon and player together, they claim the frag. The quarry can defeat this by doing the same to the hunter first. The snapshot must contain an icon with a clearly visible person beneath it to be a valid frag.
If a player is in a public place and they become a quarry, they will be notified by a normal mobile notification (sound, vibration, sms, etc.). If the hunter is within a certain distance, the quarry will be notified with a different "danger" sound.
A website tracks frags by player, area, etc. Frag verifications are crowd-sourced on the site or by email, sms, etc. Random users will be asked to verify the frags of other players.
