With Connect 4 Multiplayer, you can play an online version of the classic two-player board game for free. Practice your strategy on your own by playing against the computer, or challenge a live opponent online and play together! Drop your colored discs in the slots and try to place four in a row. Your line of discs can be horizontal, vertical, or diagonal, but it may not be interrupted by any of your opponent's discs. Players cannot skip their turn, which means that you can lay out your discs in such a way that your opponent will be forced to make plays that help you achieve a win.
