To win Connect Four you must be the first player to get four of your colored checkers in a row either horizontally, vertically or diagonally.
When it’s your turn to make a move in Connect Four, you take a checker and drop it down one of the slots at the top of the grid. Standard boards have have seven columns and six rows to choose from. On your first move, you will typically wind up placing your checker in the bottom row, but you can choose any of the columns, depending on your strategy.
After you make a move with your checker, your opponent gets a chance to go. As you plan each of your moves, try to imagine how your opponent will respond. That allows you to react to their moves quickly and decisively. Before you drop a checker into the grid, ask yourself what you would do next if your opponent had made the move that you’re about to.
