OGS Mahjong is a simple mahjong solitaire game with nice 3D graphics and relaxing soundtrack. It has been developed by the Opensource Game Studio and licensed under GPL (version 3). This game requires 3D hardware with support of OpenGL 2 or later.
There are versions for Windows and Linux.
The development of OGS Mahjong started in November 2009, and first game builds were using the Lightfeather graphics engine. In February 2010 the graphics engine was changed from Lightfeather to Ogre3D. Few months later, a first playable version of the game was released. The first beta version has been released at 2010-08-02. Right now, the Opensource Game Stusio is working on a sequel, the OGS Mahjong 2. They are planning to add the classic chinese mahjong mode to the game, and also support MacOS and Android.
