This. It's free. You can choose different "rulesets" (board sizes and how many in a row to win) by selecting "New Match". There are 4 default rulesets pitting you against the AI in preset board size and winning row length.
If you pick "New Match" you can select whether to play against another person (hotseat) or against a selectable AI (stupid, normal, smart, or hardcore). You get to pick the board size, winning row length, and the colours for yourself, your opponent, and the grid.
All in all I'd say this is a pretty good free Tic Tac Toe game, runs well in Windows 7 x64. Thanks mickey!
