About Tic-Tac-Toe
Oomi plays purple circles and your child plays stars on a three by three grid. Your child always moves first, then Oomi takes a turn after a short pause. Three in a row across, down or corner to corner wins, and the winning line lights up.
How to play
- Tap an empty square to put your star there.
- Get three stars in a row before Oomi gets three circles.
- On a computer, press 1 to 9, or use the arrow keys and Space.
What your child practices
- Taking turns
- Blocking the other player
- Thinking one move ahead
- Rows, columns and diagonals
