A simple game, no clutter
Everything you need for a quick game, and nothing more.
-
Three difficulty levels
Easy to warm up, Medium for a challenge, and Hard. On a 3×3 board Hard never makes a mistake, so a draw is the best you can get. On bigger boards it thinks a few moves ahead.
-
Boards from 3×3 to 6×6
Pick the board size in the game settings: 3×3, 4×4, 5×5 or 6×6. On bigger boards you need four or five in a row to win.
-
Two-player mode
Two players on one device: pass the phone back and forth or sit at the same computer. The game keeps score for you.
-
Keeps your score
The game counts wins for X and O, plus draws, and remembers your settings. It all stays on your device — we never send it anywhere.
-
Dark and light mode
The look follows your system settings, or you can pick a theme in the game. Calm colors that are easy on the eyes.
-
No accounts, no purchases
No account to create and nothing to buy. The game is free and supported by Google ads.
