Tiny grid, fast turns, and three marks in a row.
Section 01 · Setup
The board is a small 3x3 grid.
Players choose X or O, then take turns claiming one empty square. The grid starts empty, and every square can matter.
A diagonal win for X: three connected marks.
Section 02 · Your move
Place exactly one mark on an empty square.
Your turn is just one placement. You cannot move a mark after it is placed, so center, corners, and blocking squares are all important.
Section 03 · Tactics
Win now, block next, and watch for forks.
A fork creates two winning threats at once. If your opponent has two marks in a line, block the third square before building your own attack.
Section 04 · Turn flow
A turn, in order.
①
Check for a winning square.
If your next mark completes a row, column, or diagonal, play it.
②
Block their winning square.
Do not let the opponent complete three in a row.
③
Create a second threat.
Use center and corners to make multiple lines possible.
④
Stop when the board resolves.
The game ends on a win or when every square is filled.
Section 05 · Legal vs. illegal
What counts — and what does not.
Legal
Claiming one empty square on your turn.
Winning with a row, column, or diagonal.
Playing until all nine squares are filled.
Not allowed
Replacing an existing mark.
Moving a mark after it was placed.
Playing two marks in one turn.
Section 06 · Winning
Three connected marks wins immediately.
Connect three horizontally, vertically, or diagonally. If the board fills without a line, the game is a draw.
Section 07 · Try it
Now play a quick game.
Play a quick solo round, practice center control, and learn when to block instead of attack.
