c4arena is a fantastic two-player connect-four game. You play against your friend using split controls and you must be the first to create a link of four! You play as either red or yellow color. The gameplay is turn-based – you place a tile, then your friend places one until someone wins the round.

You can also play online against random players from around the world. See how your connect-four skills match up – can you defeat other skilled players from around the globe? Finally, you can also play against an AI opponent with three different difficulty levels. Why not give this awesome classic game a try?
