Connect Four

How to Play

Players take turns dropping discs into seven columns; discs fall to the lowest empty slot. The first to connect four in a line—horizontally, vertically, or diagonally—wins. Use the mouse or tap to choose a column. Early play revolves around building multiple threats while preventing your opponent’s immediate lines. The central columns are strongest because they support more potential diagonals and verticals.

Before every move, imagine where your opponent can reply. If your drop gives them an instant win, choose a different column or force them to defend.
