Eh. Meh. Solitaire? Eh. Microsoft’s games bundled with Windows have been the platform’s most popular to date. In fact, there may be just as many Solitaire and Minesweeper players as there are League of Legends players in the world. Microsoft has dominated the desktop market for the last 15 years and for the past 25 years of Windows there has always been some form of Solitaire available for the platform. Well, they think its time to celebrate the game’s quarter-century birthday with an official Solitaire tournament.
