Four-in-a-row free

Four In A Row(also known as Plot Four, and Four In A Line) is a two-player board game (or one player if played on a computer) in which the players take turns in dropping alternating colored discs into a seven-column, six-row vertically-suspended grid. The object of the game is to connect four singly-colored discs in a row -- either vertically, horizontally, or diagonally -- before your opponent can do likewise.
