Cube Buster is a skill game on www.flash-game.net in which you will clean up the board by destroying cubes of the same color. In the game, you will see a POW window on the right side of the screen. Wait for the top red line to charge. When the POW is charged you will be granted a special bonus, which may help you change the cube to a single color, get more points, make the game slower, or jump a level. Sometimes you gain more POW if you click the bonus icon repeatedly. Try to clean up all the cubes before they stuff the screen. Good luck!
