Start off trying to unlock the pieces around the color bomb in the center and then try to remove the 4 hit blocks to open up some space. Try to save the color bomb for the color bomb mix you need. Creating 2 will be harder later, especially right next to each other. Shooting a horizontal or vertical striped candy through the locks to release them and give the blocks a hit as well, so try for those.

This level’s pretty straightforward. Keep hitting the blocks with as much force as you can (striped, striped/wrapped combo) whatever you can to open up the board and release that color bomb to make things easier. You’ll probably make all the other orders in pursuit of the color bomb…which is best because when they combine, they really can make a mess out of the board.
