This is an implementation of the card game War in Ruby.
If you have ruby, you can download the source code and run the script with
ruby game.rb
If you don't have Ruby installed on your machine, you can download the latest release here in executable form through GitHub and run that like any other program.
After running, this script creates a file called "GameOfWar.txt" that is the result of each round of the game. If you run the script again, it will overwrite that file.
