Your score is based on how many blocks are removed at a time. To move on to the next level of play, you must survive the advance of the indicated number of lines for the level you are on. Upon completion of the level, cleared brick areas receive points and there are even bigger bonuses for cleared rows at the top. Clicking on blocks that are not adjacent to like color blocks will deduct points from your score each time. Scoring: (# of blocks)² / 10 bonus for each empty row at the end of the level - 10 x level 1000 for clearing all blocks
