The object is to clear away as many blocks as possible. If a block has at least one neighbor of the same color, you can click that block or any of its neighbors and they will disappear. Blocks on top of the blocks that just disappeared will fall down. If an entire column is cleared, then blocks will shift in from the right. Your game is over when there are no more moves left.
