FallingCrystal

FallingCrystal is a simple and addictive puzzle/ball-falling game. The crystal ball travels from one side of the board to the other. You need to tap the screen to let the crystal ball drop to the column you like before the ball returns and drops into the first column.  

Line up three or more crystal balls of the same colour horizontally or vertically to eliminate them. Once you do, the crystal balls will explode and disappear, reducing the number (and height) of the crystals still on the screen.
