|Mah-Jong is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.|
Mah-Jong is a client‐server set of programs for playing Mah-Jong written in the C programming language by Julian Bradfield, in the Chinese Classical style, against other users (locally or over a network), against programmed players, or both.
Though the game is licensed under the GPL, the author requests that any derived works respect the protocol definition, and that incompatible modifications are not distributed under the same name.
