Tic Tac Toe (also known as "Noughts and Crosses" or "Xs and Os") is one of the most popular paper-and-pencil games. This app lets you play a classic 3x3 variation of the game on your Android. The app is free and does not have ads - just enjoy the game!

Features:
- both one and two player modes
- either you or the computer can move first
- three difficulty levels
- you can take back a wrong move (or several wrong moves) - just press the "undo" button on the toolbar
- a session scoreboard keeps track of wins and losses (the score automatically resets to 0-0 for each new session).
