TicTacToe

<b>Tic-tac-toe</b> (<i>also known as Noughts and crosses or Xs and Os</i>) is a paper-and-pencil game for two players, <b>X</b> and <b>O</b>, who take turns marking the spaces in a 3x3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game.

When considering only the state of the board, and after taking into account board symmetries (<i>i.e. rotations and reflections</i>), there are only 138 terminal board positions. Assuming that <b>X</b> makes the first move every time:

<b>-</b> 91 unique positions are won by <b>X</b>

<b>-</b> 44 unique positions are won by <b>O</b>

<b>-</b> 3 unique positions result in a draw

This game can be played in two modes: <b>Player vs AI (<i>computer</i>)</b> and <b>Player vs Player</b>. The user interface is very simple and self-explanatory plus there are some nice sound effects and animations. When the game is over, click <b>Reset</b> to clear the board and play again.

I hope you like this simple game and have lots of fun playing it! Your opinion really matters to me a lot and I read all feedback left. If you take the time to leave a rating and write something <i>constructive</i> regarding how much you've enjoyed this app or any problems you're encountering, it really helps me know what to focus on for future releases. I have personally tested this app on an HTC One M8, Samsung S5, and a Samsung Galaxy Tab 7 without issue, however because there's nothing targeting any specific device make/model, it should work on any Android 4.x+ (API 14+) device.

Thanks and have fun! :)
