What solitaire games does Microsoft offer?

Microsoft offers five variations of solitaire as part of the Microsoft Software Collection: Klondike or classic solitaire, Spider, FreeCell, TriPeaks and Pyramid. Windows 8 for PC or a Windows Phone is required to play the game.

Spider solitaire features a challenging eight-column layout for players to clear in the fewest possible moves. FreeCell gives players four extra cells into which to move their cards. In the TriPeaks game, players must choose a sequence of cards in order to clear the board and earn points. The Pyramid variation requires players to find pairs that equal 13 as they climb to the top of a pyramid of cards.
