Three in a row, built for streaks: beat the Easy or Medium AI, survive the unbeatable Perfect AI, or challenge a friend on one device.

How to play

Pick a mode and press Play (or Continue to pick up a saved run).
Click or tap an empty cell to place your X. On a keyboard, press 1–9 (numpad layout) or move with the arrows and press Enter.
Get three of your marks in a row, column or diagonal to win the round (+3). A full board is a draw (+1).
Starting turns alternate every round. One loss ends your streak.
Easy makes mistakes, Medium blocks every threat (beat it with a fork), Perfect never loses.
In Duo mode, X and O take turns on one device; Undo takes back a move. The first to win 3 rounds wins the match.
Press ? or the ? button any time for help.

About Tic Tac Toe

Our Tic Tac Toe turns the 3×3 classic into a streak challenge. Every round you win against the computer is worth 3 points and every draw 1 point. The first loss ends your run, so how long can you last? Easy mode rewards clever forks, Medium blocks every threat so only a real fork beats it, and Perfect mode cannot be beaten, so your goal there is to keep drawing. Duo mode is a first-to-three match for two players sharing a phone, tablet or keyboard, with undo for mis-taps. Your run is saved automatically, so you can continue it later.
