Microsoft Mahjong


Microsoft Mahjong 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. It takes advantage of the new graphical user interface of Windows Vista, and includes features such as tile set and background choices. 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.
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 32767 possible configurations.

Features

The player has a choice of six tile layouts - Cat, Turtle, Crab, Dragon, Fortress and Spider, each a stylized portrayal of the respective object or animal. The background image can be chosen from five different options and there are four tile sets, including traditional Mahjong tiles, variations with fuller coloring or larger print, and an alternative pastel tile set with an entirely different picture theme.
Games are not entirely random. There is always at least one pair within five tiles of the topmost five tiles in the turtle layout and often two pairs. The algorithm for tile organization positions tiles such that they can mostly be paired on the same level, or otherwise a matching tile is available in an accessible position one level down. It does not check to ensure that the matching tile is not positioned beneath its partner. Since every tile has 3 partners this is not enough, by itself, to prove the game is impossible to solve.
The newer version of Microsoft Mahjong has numerous further layouts, improved graphics and sound, Internet features such as a set of daily challenges that reward the user with "badges" when completed, and Xbox Live integration.
