Party popper is awesome but hard to get. UFO is great but unpredictable as to where it will place the wrapped candies. My fave is the good ol' colour bomb.
My favorite booster is the lollipop hammer. It can be useful on many different boards, whether you need to hit that popcorn one more time or clear a jelly square that is isolated and hard to reach.
My favourite booster is Color Bomb because when you make combos with Special Candies and Boosters, it’ll be really handy to when you are clearing the jelly or dropping down the ingredients, or both! 😊
