Marble Lines at Cool Math Games:
I've played this game over and over and over.
You shoot the ball to hit balls of the same color to make them disappear.
If they get past you to the hole, you lose!

INSTRUCTIONS
Destroy marbles by forming groups of 3 or more marbles of the same color.
Click the mouse to shoot the marbles. Press the space bar to swap the color of the marble to be shot.
