Tic Tac Toe - 2 Player XO AI

THE CLASSIC XO GAME, DONE PROPERLY Tic Tac Toe with a clean, modern board and no clutter. Play a friend on the same phone, or take on the computer at three difficulty levels. Fast to start, easy to put down, and it works with no signal at all. TWO WAYS TO PLAY - 2 Player - pass the phone and play noughts and crosses against a friend on one device. No second phone, no account, no waiting for a turn. - Vs Computer - play against the AI when nobody else is around. THREE LEVELS OF AI - Easy - makes mistakes, so a first game is winnable. - Medium - punishes the obvious errors but can still be beaten. - Hard - a minimax opponent that plays the game out perfectly. A draw is the best result available to you, which is exactly how tic tac toe works when both sides play well. WHY THE HARD AI CANNOT BE BEATEN Tic tac toe is a solved game. With perfect play from both sides it is always a draw. The Hard opponent searches every remaining position before each move, so it never makes a mistake you can punish. If you force a draw against it, you have played the game perfectly - that is the win condition on Hard. HOW TO PLAY Two players take turns marking squares on a three by three grid, one as X and one as O. The first to line up three of their marks in a row - across, down or diagonally - wins. If the grid fills with no line, the game is a draw. X always moves first.
