To pass level 72 it’s important that you focus on destroying the top candy pieces before they mutate to many of your candies. After doing this you will need to build special candies and eventually break the nets to the bottom half of the board. Creating as many special candies first will help you to destroy the chocolate efficiently. This level isn’t so bad as long as your ingredients to not drop in the far left or right lower boxes. Try to avoid them going here as getting them released is difficult and can take a lot of your moves. Playing centrally will help this.
