How do you play Connect Four?
Two players take turns dropping coloured discs into a 7-column, 6-row grid. Discs fall to the lowest open slot in the chosen column. The first player to line up four of their discs in a row — horizontally, vertically, or diagonally — wins. Connect Fo plays by the classic Connect Four rules, with a coin flip at the start to decide who chooses to go first.
