Tic Tac Toe unblocked: play Tic Tac Toe online free right here in your browser — no download, no sign-up, works on a school Chromebook.
Tic Tac Toe is the oldest pencil-and-paper duel there is: a three-by-three grid, one player on X, the other on O, and the first to line up three in a row wins. On Bloons TD it is the odd one out, a game with no balloons, towers or upgrades, and that is exactly why it works as a break between long tower defense runs.
A round takes under a minute. You make a move, your opponent answers, and within nine placements the board is either a win for someone or a full grid with no line, which is a draw. When the round ends the game restarts by itself, so you can go straight into a rematch without touching a menu.
It is built for two people sharing one screen, which makes it a natural fit for a Chromebook passed across a desk. It runs in the browser with nothing to install.
How to play
The catalogue notes that both players share a single keyboard: player one uses the arrow keys and player two uses WASD, each with one action key that the start screen names. Check that screen before your first round, because it is the authority on which key places a mark.
Players alternate turns. Get three of your marks in a straight line, across, down or diagonally, and you take the round. If all nine squares fill with no line, nobody scores and you start again.
Tips
- Take the centre if you can. It sits on four of the eight possible winning lines, more than any other square.
- Corners beat edges. If the centre is gone, a corner gives you three lines to work with, while an edge square gives you only two.
- Look for the fork. The strongest setup is a move that creates two threats at once, since your opponent can only block one.
- Always check for a block first. Before building your own line, make sure your opponent does not already have two in a row.
Between two players who both follow these rules, the game is a draw. Wins come from the other person missing a fork or forgetting to block, so rounds against a friend are about spotting mistakes quickly.
