Drop Stack Ball is a cool reaction game you can play online and for free on Silvergames.com. Your task in this fun addicting challenge is to make the bouncy ball break through the colored parts of the platforms in order to reach the bottom of the tower. If you try to break the black parts you will lose, so be really careful not to hit those if you want to keep advancing. Fill the round bar that appears in the middle of the screen to activate the fire mode, with which you can crush the black parts as well for a few seconds.
