Microsoft Mahjong

Microsoft Mahjong (formerly Mahjong Titans, Shanghai Solitaire and Taipei) is a computer game version of mahjong solitaire published by Microsoft. The version titled Mahjong Titans was developed by Oberon Games and included in Windows Vista and Windows 7 (except Starter and Home Basic editions). It takes advantage of the new graphical user interface (GUI) of Windows Vista, and includes features such as tile set and background choices. (In Windows Vista builds 5219 up to 5259, the game was known as Shanghai Solitaire.) The game did not make it to Windows 8; however, a standalone version, developed by Arkadium and published by Microsoft Studios, can be downloaded from the Windows Store free of charge and played without download on the web.

An older version of the game was known as Taipei and was bundled in Microsoft Entertainment Pack 1 and Best of Microsoft Entertainment Pack. That version included 32,767 possible configurations.

A mobile version of the game was released on iOS and Android, known as Mahjong by Microsoft.
