How to play Tic-Tac-Toe
- 1
The board is a simple 3×3 grid of nine squares, and the goal is to be the first to line up three of your own marks in a row.
- 2
X always goes first, then players alternate turns — one mark per turn, tapping any empty square to claim it.
- 3
Get three of your marks in a row to win — across a row, down a column, or along either diagonal counts.
- 4
Once a square is taken it can't be changed or moved, so think a move ahead before you tap.
- 5
If all nine squares fill up and neither player has three in a row, the round ends in a draw.
- 6
Play solo against the computer — choose Easy or Medium for a fair fight, or Perfect if you want a real challenge — or pick Play with Friend for quick local rounds or an online invite link.
