Connect Four is the beloved vertical strategy game. Drop your coloured discs into a seven-column grid and try to line up four in a row — horizontally, vertically or diagonally — while stopping the computer from doing the same. It's easy to pick up but full of tactical depth as the board fills up and threats stack on both sides.
Be the first to line up four of your discs in a row horizontally, vertically or diagonally.
