Connect Four

7×6 gravity board in this tab. Drop discs with a friend or the built-in AI.

Red to drop

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

A quick round between two people on one phone. A short match against the AI. Something to open without an account or a download.
