Connect 4

Guess what Connect 4 in an online version of Connect 4. It appears to follow the usual format for these kind of online multiplayer games; players must register, once registered players are placed in a waiting lobby, then a player can either join someone who has started a game and is waiting for an opponent or start their own game.

Unfortunately when I had a look at the game there were no other players around so I can't determine how well the site copes with an actual game. It looks good though.
