Tic Tac Toe
This module implements an interactive Tic Tac Toe game
It can present a Tic-Tac-Toe board that is updated using AJAX requests upon each user move.
The module implements the alpha beta search algorithm (Minimax search optimized by performing alpha beta pruning) for determining the next move, which are common algorithms for zero-sum two player games (e.g. Tic Tac Toe and Chess).
Download raphael-min.js here and rename it to raphael-min.js than put into the directory sites/all/libraries/tic_tac_toe
All version of Tic Tac Toe requires the Libraries API module
I'm quite busy at the moment so it may take a while until I will start developing it.
