Short description of 4 In A Row 2.03: Outwit the computer in this simple but very addictive strategy-logic game. Prevent the game field from filling up with blocks by moving them so they form lines of 4 or more of the same color. The lines are removed, but the computer adds more blocks. THERE MUST BE A PATH TO THE DESTINATION ! If there is a path, the chosen block is moved along that path to the destination and any new lines formed are removed and you earn points.
