Tic Tac Toe
Nine squares, two symbols, three in a row wins — the rules haven't changed since it was played with pencil and paper. What's here is two ways to play it: pass the device back and forth with a friend in 2 Players, or take on a CPU that can be tuned from careless to unbeatable.
Playing a round
- Tap a square to place your mark — X always moves first.
- Take turns filling the grid.
- Three marks in a row, across, down, or diagonally, wins.
Choosing an opponent
Easy makes plenty of mistakes and rarely blocks an obvious win. Medium plays reasonably well without being perfect. Hard never slips up — which, against a game this simple, means a perfectly played match against it can only end in a draw, never a win. 2 Players skips the CPU entirely and just passes the same screen back and forth.
Frequently Asked Questions
What's the actual difference between Easy, Medium, and Hard CPU?
Easy makes plenty of mistakes. Medium plays reasonably well but isn't optimal. Hard never slips up, so a perfect game against it always ends in a draw.
Is there a way to never lose against another person?
Taking the center square first and always blocking an opponent's two-in-a-row prevents most losses, though a perfectly played game between two people always ends in a draw.
Does X or O always go first?
X always moves first, in both 2 Players and vs Computer.
