Quick history of the
GAME OF FIFTEEN
The puzzle was "invented" by Noyes Palmer Chapman, a postmaster in Canastota, New York.
Bobby Fischer was an expert at solving the 15-Puzzle. He had been timed to be able to solve it within 25 seconds; Fischer demonstrated this on November 8, 1972
The unsolvable variation happens, when numbers from 1-13 are in order, but 15 is placed in front of 14.
The 15 puzzle, also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others.
