In this puzzle, the player must crack the code by matching up the numbers on bordering dials. When two numbers match, part of the blacklight will turn on to illuminate a partial message. If the dial is turned so that the numbers don't match anymore, that part of the blacklight will turn back off. The objective is to find the orientation where all of the numbers match, in order to illuminate the full message. To reset the game, each dial would be spun by a motor for a different amount of time before the next group enters.
