This tutorial includes a complete Tic-Tac-Toe game, with Human vs. Computer, Human vs. Human and Computer vs. Computer support.

This is a complete rewrite of the original turn-based game tutorial using only standard Unity components supplied with the free version of the Unity Editor. Everything you need is included in the package. Just install into an empty project and you're good to go!

Now with over 140 pages of documentation (PDF and ePub formats) in the 'Documentation' folder. Complete coverage of the game, its development and its concepts. All necessary scripts are included. And now includes new "Programming Primer" ebook - a preview version of a book intended for publication later in the year.

Prerequisites - read BEFORE buying: the tutorial assumes you have followed Unity's own tutorials and know your way around the Unity Editor. You are NOT expected to be an expert programmer: the "Programming Primer" ebook is intended to help people new to programming.
