4 in a Row Classic

'4 In A Row' is another version of a classic game played either on board or as pen and paper (this game is also called '4 in a line', 'Connect 4'). The goal is to outsmart your opponent (computer of human) and connect 4 'disks' in a row (horizontal, vertical, diagonal - whatever) on a 7x6 field board. The catch is this - when you pick a place for your disk, there must be something below it (another disk or the bottom line). Simple at first sight, this game has a quite of lot of strategy involved. For example, if you want to be successful, you need to control the center of the board. That will give you more opportunities to match those disks.
