Who Took the Apple? is a cardgame played backwards in time. The goal of the game is to take an apple which is placed under a bucket. Players "pre program" their actions, like in Space Alert or Roborally, but cards are played backwards in time: First card played will be last action happening. In the second phase of the game, all players go through their actions to resolve what actually happened. Some actions might be impossible to carry out which creates a paradox. These cards are ignored in order to restore space/time logic. Players have to maintain multiple possible game states in their head in order to successfully play.
