How to Play Connect 4
Choose a column to drop your disc. Pieces settle from the bottom upward, so every move changes the positions available on the board. Win by connecting four of your discs horizontally, vertically, or diagonally. A completely filled board without a winning line is a tie.
Connect 4 Strategy Tips
Watch the center columns because they can participate in more possible four-disc patterns. Before each drop, check whether you can create a winning threat and whether your opponent has a move that must be blocked. Strong positions often come from creating two potential winning moves that cannot both be defended.
