An interesting puzzle created in the 19th century by Sam Loyd, described by Martin Gardner as "America's greatest puzzlist."

The object of the puzzle is to transpose the positions of the gold and silver pieces in the fewest number of moves.

Note: The shortest known solution, discovered by the British puzzle expert H. E. Dudeney, consists of 46 moves.

Click on a piece with the mouse to move it into the vacant square. A piece may either be moved to an adjacent vacant square, or jumped over an adjacent piece (of either color) to the vacant square. No diagonal moves or jumps are permitted.

The Solve button will initiate a search for a solution, then run the found solution. If you're curious, the technique used to find a solution is called Depth-First Search.
