TicTacToe

井字游戏是一个游戏两名球员谁轮流选择在网格中的X或O操作。

Tic-tac-toe (also known as Noughts and crosses or Xs and Os) is a paper-and-pencil game for two players, X and O, 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.e. rotations and reflections), there are only 138 terminal board positions. Assuming that X makes the first move every time:

- 91 unique positions are won by X

- 44 unique positions are won by O

- 3 unique positions result in a draw

This game can be played in two modes: Player vs AI (computer) and Player vs Player. The user interface is very simple and self-explanatory plus there are some nice sound effects and animations. When the game is over, click Reset 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 constructive 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! :)
