Cockatrice by Max-Wilhelm Bruker is an open-source multiplatform software for playing card games, such as Magic: The Gathering, over a network. It is fully client-server based to prevent any kind of cheating, though it supports single-player games without a network interface as well. Both client and server are written in Qt 4. Cockatrice is fully GPL licensed and thus free software. Ported to Pandora by Canseco. Read more about Cockatrice v24.06.2012.2 (Pandora Game Port)
