How to Play

Classic tic-tac-toe

1. X goes first and O follows.
2. Choose an empty space on the 3×3 board.
3. Make three in a vertical, horizontal, or diagonal line to win.
4. If the board fills with no winner, the game is a draw.

Vanishing mode

When you place your fourth mark, your oldest mark disappears. The blinking mark shows what will disappear next. Plan for the space that opens up.

One-player mode

Choose One player to play against the CPU. You can choose who goes first and select Easy, Normal, or Hard.
