Legend says that Solitaire was invented to entertain Louis XIV, The Sun King who ruled from 1643 to 1715. A French engraving dating from 1697 shows Princess de Soubise playing the game of solitaire. This humble game of strategy has challenged and stumped mathematicians, royalty, and the run of the mill game-players for centuries. It’s no wonder that Solitaire has captivated so many throughout the years. One could spend an entire morning (afternoon and evening) trying to win at this game.
