Cockatrice is an open-source multiplatform supported program for playing tabletop card games over a network. The program's server design prevents any kind of client modifications to gain an unfair advantage in a game. The client also has a built in single-player mode where you can brew without being connected to a server. This project is written in C++/Qt with support for both Qt4 and Qt5.
