Realizing that, Microsoft has just added three of the most popular Windows PC timewasters ever made to Windows Phone: Solitaire, Mahjong, and a new version of Minesweeper. Microsoft doesnt have any special claim to these games, and you can find plenty of other companies selling versions of them on Windows Phone and any other platform you can name. Still, Microsofts versions have been a key part of Windows for many years now, and if these copies are any good theyre likely to be very well received. Plus, each has Xbox Live integration, so you can compete with friends on Microsofts leaderboards.
