Tic-Tac-Toe
Take turns placing X and O on a 3 × 3 grid; the first to line up three wins. Challenge a friend on one device, or face the computer — relaxed or completely unbeatable — and keep score across a best-of series.
How to play
- 1
Choose an opponent
Hand the device to a friend, or play the computer. Relaxed makes mistakes; Unbeatable never does.
- 2
Take turns
X always opens. Tap an empty square to claim it, then it's the other side's move.
- 3
Line up three
Three marks in a row, column or diagonal wins. A full board with no line is a draw.
- 4
Play a series
Keep playing to build a scoreboard. The starting side alternates every game so it stays fair.
