Marble Line 2 is an interesting arcade game on www.flash-games.net for free. The goal for you is to destroy marbles by forming groups of three or more marbles of the same color. In this game, you can click the mouse to shoot the marbles to the positions you want and press the space bar to swap the color of the marble to be shot. If the marbles accumulate without timely smash, the line will enter the hole in the middle and you lose the game. When all the marbles are destroyed, the level will be passed. Come on and good luck!
