If you need a quick game of Reversi, or are looking for something to teach you how to play or how to improve your skills, this program is for you!

You play against Keyano, a Reversi artificial intelligence program I wrote many years ago. Keyano was one of the top Reversi players (either human or computer) when it retired from open competition.

This version includes six different AI levels to play against (from Beginner to Diabolical), the ability to undo your moves (in case you make a mistake), and tutorials that will help you learn how to beat the easiest difficulty levels.

Keyano can make you into a great Reversi player. Try it out today!
