How to use

  1. You're Yellow. Click any column to drop your piece - it falls to the lowest empty row.
  2. Connect 4 of your pieces in a straight line to win. Lines can go horizontal, vertical, or diagonal.
  3. The computer plays Red. It will try to block your lines and create its own, so plan ahead!
  4. If the board fills with no winner it's a draw. Score is tracked across rounds in the session.
