Multi-colored stones on the playing field - this is your goal to remove in the game Block Collapse Grand Challenge. Look for groups of three or more identical, collected side by side and click to remove from the field. Level objectives are located on the right of the information board. If you manage to blow up seven elements at once, you will receive a present: a bomb or a magnet with an arrow. Both bonuses will help you complete the level faster by collecting the required number of points. You can remove one element at a time, but only by donating 200 points, but you don’t need it at all. Do not clear the field, repeat the level again.
