Tic-Tac-Toe 3D

An enhanced version of Tic-Tac-Toe 3D is now available for Windows Phone 7. Get it here.

Everybody knows how to play Tic-Tac-Toe. How about the same classic game but in 3D? Play it here and rediscover the classics.


The objective of the game is to align more lines of 3 items (in any direction) than computer.

Drag the board with your mouse to rotate it, place X by clicking on a cell. Center cell of the middle board is off limits.


This game was initially developed for MIX 10k Challenge - a contest to create the best Silverlight/HTML5/Gestalt app with source code of less than 10kb. And it won a Community Prize! (see the original here).

The version here is elaboration of that MIX 10k entry and even though it looks nicer and richer it's code design hasn't been fully refactored. Since the initial objective was small source size and not the best software design practices and coding standards, the code is still ugly. So, don't teach yourself programming by looking at this code.

This game is open source. It was developed in Silverlight 3 (C#). The sources are released under Ms-PL license. You can download them below.
