Pass 210 challenging levels to finish the game! The center of the playing field is made up by mutliple colored blocks. At the field edges - up, down, right and left - your playing blocks are ready to be launched. Select any block from the row closest to the field and click on it. It will move along a straight line until it bumps into another ball or the field edge. If blocks of the same color land next to each other, they will disappear. Your objective is to clear the playing field and then you can proceed to the next challenging level.
There is no time-limit to each level, but the complexity grows with each level. There are five different game modes to choose from.
