Tic Tac Toe unblocked takes the paper-and-pencil favorite and moves it online. Line up three of your marks vertically, horizontally or diagonally before your opponent does, chatting as you go. If no human player is available, AI bots step in so you can always get a match going on Classroom 7x.
About Tic Tac Toe
Few games are as universally known as this one, and this version keeps the rules exactly as you remember them. Two players take turns placing their marks on a three-by-three grid, and the first to complete a line of three in any direction wins. If the board fills up without a winner, the round ends in a draw. Because each game only takes a minute or so, it is easy to squeeze in round after round and work on your strategy.
This edition adds a few modern touches to the classic. It is built for two-player matches, and when real opponents are not around, AI bots fill in so you are not stuck waiting. A built-in chat system lets you talk with your opponent, and usernames can include emoji for a little extra personality. The fun, casual theme and simple one-touch gameplay make it a relaxed way to test your thinking against friends, family or anyone else who joins.

- Try to line up three of your marks vertically, horizontally or diagonally.
- Block your opponent whenever they have two in a row with an open third square.

Tips and Tricks
- Take the center square when you can. It is part of four possible lines, more than any other square on the board.
- If the center is taken, grab a corner. Corners belong to three lines each, while edge squares only belong to two.
- Always check for a block before making your own move. Spotting your opponent's two-in-a-row first saves many games.
- Set up a fork, where one move creates two different ways to win. Your opponent can only block one of them.

Tic Tac Toe FAQ
What happens if no other players are online?
AI bots step in as replacements when human opponents are unavailable. That means you can still start a match and practice your strategy, even at times when nobody else is looking for a game.
Can a game of Tic Tac Toe end in a draw?
Yes. If all nine squares fill up and nobody has three in a row, the round is a draw. When both players make the best possible moves every turn, the game will always end in a tie.
What is the best first move in Tic Tac Toe?
Most players start in the center because it is part of four possible winning lines. A corner is another strong choice. Edge squares are weaker openings since each one only belongs to two lines.
Can I play Tic Tac Toe on a school Chromebook?
Yes. Tic Tac Toe runs in the Chrome browser on Chromebooks, Windows PCs and Macs with nothing to install. It is designed for a keyboard and mouse, so it plays best on a computer rather than a phone.
Is Tic Tac Toe free to play?
Yes, Tic Tac Toe is completely free on Classroom 7x. There is no download, no account and no sign-up. Press Play and the game loads right on this page.
