Instruction: Move the discs and discover the rules.
Implementation: The program stopped when all discs were moved from Start to Goal. The program only allowed moves complying to the shortest selection of moves to reach the goal. A bigger disc could not be put on top of a smaller one. False moves were indicated with a "beep" and the disc was put back to the original position. A correctly positioned disc could not be removed.
