This is the first alpha release and there is still a lot to be done. Currently two games are implemented; `knockout whist' and `Montana red dog' (rules are in <gamedir>/RULES).
Both the servers and graphical clients require a standalone java interpreter (1.1 or higher) ie they will NOT run in a web browser. However if you don't have java it is possible to play on a remote server using a telnet client.
