About this game
About the Tic-Tac-Toe strategy game
Tic-Tac-Toe is a turn-based strategy game on a 3 × 3 board. One player uses X and the other O; X moves first. Take turns claiming an empty cell. Complete a horizontal, vertical or diagonal line of three marks to win. A full board without a winning line is a draw.
Play against the computer or share one device with another player. Computer mode offers Easy, Normal and Hard levels and lets you choose X or O. Local two-player mode alternates turns on the same board. Each small-board decision can create an attack, block a threat or prepare the next turn.
Features in this version
Computer or local friend
Challenge the AI or take turns with someone nearby. Two-player mode uses the same device, not an online matchmaking room. AI difficulty applies only in computer mode.
First move and undo
Choose X to move first or O to let the computer start as X. Undo is available before a round ends. Against AI it restores your move and the computer's reply together; history ends on refresh.
Results and saved rounds
Wins highlight the completed line. X wins, O wins and draws are counted separately. The board and statistics save in this browser so you can continue playing more rounds.
Getting started
- Check for an immediate winning move first. If there is none, check whether your opponent can win on their next turn and block that threat.
- The center connects several possible lines, while corners contribute to rows, columns and diagonals. Consider these future connections when opening.
- Create a fork: two threats that would both need blocking. Watch for the same opportunity in your opponent's position.
Frequently asked questions
Can I invite a remote friend in two-player mode?
Two-player mode currently shares one device. Players take turns clicking or using the keyboard. There are no online rooms or remote matchmaking features.
Why do games against Hard AI often end in a draw?
Hard mode searches future board positions to choose a move, seeking wins and avoiding preventable losses. If both sides defend well, the board can fill without a winning line; a draw is a normal result.
Does undo keep every round in this page?
Undo applies to the most recent move in the current unfinished round. Against AI it returns to before your move; local mode steps back one mark. Refreshing or starting a new round clears undo history.
