What is TripleA:

Triplea is a networked open source gaming engine and clone of a popular board game. Triplea is released under the Gnu Public License (gpl). 

Installing:

Please read the installation page. 

Before you run the game you must first install the java runtime environment (JRE) on your machine (instructions are provided on the installation page).

How do I play:

On windows to play the game you simply double click on the triplea.bat file in the bin directory.

On mac and linux you need to run the triplea.sh command in the bin directory.

To do that open a terminal prompt, cd to the bin directory, and then execute the following 2 commands,

chmod +x triplea.sh
./triplea.sh

If you are using a mac, and you dont know how to use the terminal, please read this  instruction on how to use a terminal here.

Common Problems:

Windows

If you run the game and you get an error message that says 'Bad command or file name', then you haven’t installed or set up the java virtual machine correctly. Please see the installation page for instructions on setting up a java virtual machine on your computer.

Linux and Mac:

All I get is :

Exception in thread "main" java.lang.NoClassDefFoundError: games/strategy/engine/framework/GameRunner

Solution:

Are you running the command in the bin directory?  type pwd, and the result should end in /bin.  If you arent in the bin directory, change your directory.
