Instant Insanity II
Abstract:Instant Insanity II is a sliding mechanical puzzle whose solution requires the special alignment of 16 colored tiles. We count the number of solutions of the puzzle's classic challenge and show that the more difficult ultimate challenge has, up to row permutation, exactly two solutions, and further show that no similarly-constructed puzzle can have a unique ultimate solution.
