4 ingredients to get down to the bottom and only one on the board to start with, you need to work on the 5 hit blocks to get to the locked pieces and then send the pieces down and out. Try to make as many vertical striped candies as you can, shooting them through to get moving through faster. Try to make non striped candies that hit at least 2 of the blocks at once if not creating a striped candy. You can also try to drop a horizontal striped candy to the bottom of the top half and shoot it off to help clear up the top.
