The rules are easy: A bunch of players connect their iPhones or iPods via WLAN or Bluetooth. After the host has selected a time range and started the game, a countdown will start and notify every player with visual and haptic feedback when the round starts. Everyones goal is to stop the time as near as possible to the given time. Winner and losers will get notified after everybody stopped their time. The winner is now allowed to punish the losers. ;)
