The goal of this project was to create a command line version of chess in Ruby.
The project is from The Odin Project.
If you have Ruby installed:
$ git clone https://github.com/ellielle/chess.git
$ cd chess/lib
$ ruby game.rb
For Windows users without Ruby installed, you can get the release from here. It contains everything you need to run it, and you won't need to install Ruby. This was built using OCRA.
