Drop a disc, block a line, build your own: 4 In A Row brings the familiar connect-four board to the browser. You and your opponent take turns, and whoever first lines up four discs of one color, across, up and down or on a slant, takes the round.
Three ways to play are on offer: the computer at one of three difficulty levels, a friend taking turns on one device, or another player in multiplayer. Start against the easiest AI to get a feel for diagonal threats, the ones players overlook most often. More board games, such as Backgammon Online, are waiting on the site.
