In the late 1870's, the Fifteen Puzzle was widely introduced in the United States by Sam Loyd who stirred-up interest for the game by promoting a contest.  He offered a thousand dollar reward to the first person who could solve his number sliding puzzle.  The contest puzzle tiles were arranged in numerical order with only the 14 and 15 tiles reversed.  You then have to skillfully and systematically slide the tiles with out removing them from the board until you recover the original numerical sequence of 1-15 as show on the box.  The one thousand dollar reward for the first correct solution remains unclaimed, and people continue to rack their brains.  This item will be shipping in our exclusive and beautiful Value Line packaging.
