Tic-Tac-Toe is a horrible choice for a game as it's impossible to win if both players stay awake. It seems the author has realised this and therefore implemented the rotation effect that makes it unpleasant to focus on the board, undoubtedly in an attempt to break your concentration so you'll make a bad move once in every thousand games.

Version 2: I'm sure coding this was a valuable learning experience but as a game it is not very good. The spinning cubes are an interesting touch but nothing special and the gfx in general are quite ordinary. There are also no sounds or music (not that such a simple game needs music) and the menus are very simple. The AI does seem to work well though, even if it is easily beatable. All in all this game would deserve 1.5 stars but since such a score is not available, I'll give it a 2/5...
