This game is designed to be played in any workplace, by colleagues or representatives of different departments, in about a minute per workday. The goal is to reach four designated rooms on an office building map and then be the first to reach the "project completed" field. On each workday, the players can move from the staircase to any empty room - the first player to show up at work can play first, the next ones in order of their appearance. A room that has been reached is marked on a personal success field. When all players have made a move, a random floor is blocked and anyone on that floor cannot go back to the staircase, thus not reach any new room in the next move (on the next workday). The first player/team to reach the "project completed" field is the winner. (User summary by HilkMAN)
