What is Connect Four?
The 7×6 classic: take turns dropping discs into a column, and the first to line up four — across, down or diagonally — wins. Discs fall with a satisfying drop, the winning four light up, and a full board with no line is a draw.
The computer plays a real minimax strategy, not random moves: Easy makes casual mistakes, Medium plans ahead, Hard reads many moves deep and punishes traps. Or play a friend — on one device turn by turn, or online in a private room via code, link or QR, with rematch one tap away.
