How to play Connect Four
- Choose a column to drop your disc into the lowest available space.
- Take turns with the computer and connect four discs horizontally, vertically, or diagonally.
- A full column cannot accept another disc. A full board without a winner is a draw.
Try this: Center columns offer more possible lines. Check both diagonal directions before committing to a move.
