Connect 4 Multiplayer is a classic board game in which you have to plot four in a row with your colored discs. You can play this online version of the game against other active players from around the world, or practice against the computer alone to perfect your strategy. Drop your colored discs into the slots and try to connect four by making an uninterrupted horizontal, vertical, or diagonal line. The first player to get four in a row wins the game. Your opponent will try to block your attempts. Try to force your opponent to make moves that will ultimately result in a win for you.
