The game Bool the Miner is the result of a student project developed over two terms in a course on the design of serious games at Ulm University. Players direct the titular character Bool towards escaping from a mine. Each level represents a Boolean equation; the missing operations need to be inserted in switches to unlock the gate to the next level. Bool can record movement patterns for his helpful ghost companions, in order to operate multiple switches at the same time, while he completes an obstacle course towards the exit gate. As such, the game is a combination of the puzzle and jump'n'run genres. A pilot study investigated the validity of the game's approach towards practising knowledge of Boolean algebra, conducted alongside a psychological study on the effects of affective feedback as part of a multidisciplinary research project.
