Tic Tac Toe Printable

Tic tac toe is the perfect paper game for restaurants, road trips, classrooms and waiting rooms. The printable pack has boards in several sizes and layouts, and you can play right here — against a friend or against the computer, which is unbeatable on hard.

What’s in the pack

All pages print on US Letter or A4. Laminate a page and use dry-erase markers to play again and again.

How to play

1. Draw a 3 × 3 grid (or print one).
2. Players take turns: one is X, the other O. X usually goes first.
3. Place your mark in any empty square.
4. The first player to get three marks in a row — across, down or diagonally — wins.
5. If all nine squares fill up with no row of three, the game is a draw (“cat’s game”).

Alternate who goes first between games to keep it fair.

Strategy that works

• Take the centre if it’s free — it belongs to four winning lines.
• Corners are next best: each is part of three lines.
• Always block your opponent’s two-in-a-row before building your own, unless you can win immediately.
• Create a “fork”: a move that threatens two lines at once so your opponent can only block one.
• If your opponent takes a corner first, take the centre to avoid losing.

Why the computer can’t lose

Tic tac toe has only 255,168 possible games, so a computer can look ahead to the end of every one. The unbeatable mode uses the minimax method: it assumes you’ll play your best, and picks the move that leaves it the best guaranteed outcome. Perfect play from both sides always ends in a draw — a nice way to show children that careful thinking can guarantee a result. The easy mode makes random moves most of the time, so younger players can win.

Worked example: setting up a fork

Playing X and moving first, a player takes the top-left corner. The computer (O) wisely takes the centre. X takes the bottom-right corner, O takes a side square, and the game ends in a draw with correct play. Against the easy computer, though, if O answers the first corner with an edge square instead of the centre, X can take another corner and set up a fork — two threats at once — and win on the next move.

Tic tac toe in the classroom

• Review games: answer a question correctly to place your mark — great for spelling, maths facts or vocabulary.
• Probability and logic: count how many ways X can win from a given position.
• Coordinates: name squares as A1–C3 and call moves aloud.
• Maths version: players place numbers 1–9 and try to make a line totalling 15.
• Early finishers: keep a stack of printed boards on the side table.

Variations

• 4 × 4 board: four in a row to win — the printable pack includes these boards.
• Misère: the player who makes three in a row loses.
• Ultimate tic tac toe: nine small boards inside a big one; your move decides which small board your opponent must play in.
• Numerical: players use numbers 1–9 (odd vs even) and aim for a line adding to 15.
