Tic-Tac-Toe

Tic-tac-toe in a calm, clean design. You pick the board, from the classic 3×3 up to 6×6, and play the computer or a friend on the same phone.

Three difficulty levels
• Easy: a warm-up, the computer plays mostly at random.
• Medium: wins when it can and usually blocks your moves.
• Hard: on a 3×3 board it 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
• 3×3: three in a row wins.
• 4×4 and 5×5: you need four in a row.
• 6×6: five in a row wins.

Two-player mode
Two players on one phone: pass it back and forth after every move. The game counts wins for X and O, plus draws.

Set it up your way
• Play as X or O, and the computer takes the other symbol.
• Choose who goes first: X, O or take turns.
• Dark, light or system theme.
• Sounds and vibration can be turned off.

No account, no purchases
No account to create and nothing to buy. Your settings and score stay on your phone. The game is supported by Google ads: a banner at the bottom of the screen and a full-screen ad at most once every five games, never during a game.
