How to Use
Connect Four is the classic vertical strategy game on a 7×6 grid. Take turns dropping discs into columns; gravity stacks them. Connect four of your color horizontally, vertically or diagonally to win — if the grid fills up, it's a draw. The built-in AI wins when it can, blocks your threats, and favors the center column. One minute to learn, deep enough to replay forever.
