Game Instructions & Description
How to Play Tic Tac Toe
Play tic tac toe online for free against the computer or a friend in this version made by the CrazyArcade team. There are three boards to choose from. Classic is the familiar 3x3 grid: X and O take turns, and three marks in a row across, down or diagonally wins. If all nine squares fill with no line, the game is a draw. Five in a Row uses a 15x15 grid, and the first player to line up five or more marks in a straight line wins. Ultimate is a 3x3 grid of nine small boards. The square you choose inside a small board sends your opponent to the matching small board, so playing the top right square sends them to the top right board. Three in a row wins a small board, which then shows one big mark. Win three small boards in a row to win the game. If you are sent to a board that is already won or full, you may play in any open board. The boards you may play in glow. Against the computer you can pick Easy, Medium or Hard. On the 3x3 board Hard is called Impossible because it plays perfectly and can never be beaten. You play X and the computer plays O. The first move switches sides after every finished game, and a tally counts wins and draws for the session. Your best win streak against each computer level is saved on your device.

Pro Tips to Win
- On the 3x3 board, Impossible never loses, so a draw is the best result. Against Easy and Medium, look for a move that creates two lines that each need one more mark, since only one can be blocked.
- In Ultimate, think about where your move sends your opponent. Avoid picking a square that sends them to a small board they are about to win.
- In Five in a Row, an open line of three with empty squares on both ends must be blocked right away. If you let it become an open four, it cannot be stopped.
Frequently Asked Questions
Q: Who goes first?
A: X starts the first game. After each finished game the first move passes to the other side. Each board, opponent and level keeps its own tally and turn order for the session.
Q: What happens in Ultimate if I am sent to a finished board?
A: When the small board you are sent to is already won or completely full, you can play in any small board that is still open. If every small board is finished and no one has three in a row, the game is a draw.
