To play you just have to connect with a telnet client to at port 3333 or default port 23. There are also special Mud-Clients, such as zMUD for Windows Systems or TinyFugue for Unix/Linux.

Alternatively you can also use the Java Telnet Applet below. Just click on the button and it will open in a new window.

Once you are connected to the game, follow the instructions on the screen. Your first step will be most likely to create a character.
