To score 100 of the 3 pieces each, it’s going to take some work. You need to break through the 5 hit blocks to get to the locked pieces, and spinners, and then hit the cannons to clear up some pieces, You can shoot vertical striped candies down to either unlock the pieces or take out parts of the cannon, but aim for the blocks first, try to make horizontal matches to remove more pieces at once.

Use striped/wrapped combos to help remove those thick blocks and licorice whirls. Then work on the pizzas. Color bomb/striped combos can really help clear the pizzas. Every time you clear a pizza and the board clears, all the greens, purples and yellows count towards your orders.
