What Connect Four is

Connect Four is a two-colour drop game in this tab. You and the other side take turns dropping a disc into one of seven columns. The disc falls to the lowest empty cell. The first to line up four of their colour — across, down, or diagonal — wins. A full board with no four is a draw.

How to use it

  1. Pick Play vs AI or Two-player. Against the AI, set Easy, Medium, or Hard.
  2. Tap a column to drop your disc. It lands on the lowest open cell.
  3. Undo takes back the last turn. New game clears the grid.
  4. Line up four of your colour — across, down, or diagonal — before the other side does.

Common uses
