Sequential Movement - Fifteen Puzzle

Fifteen Puzzle
Category:Sequential Movement
Pieces:15, plus tray

The first known Fifteen puzzle was made by the Embossing Company of New York in 1865. About eight years later, Sam Loyd reintroduced it and it became the Rubik's Cube of the 1800's. Everyone was playing it. Variations of this puzzle, most with nothing more than other artwork replacing the numbers, continue to this day with everything from Escher drawings to three-dimensional fish making up the fifteen pieces. It's actually not so easy to find one with just the numbers.
