How I Like the In-Game Boosters: Top 1, 2, 3, 4, and 5. *Indicates Boosters I Never Had
Party Booster. Clears the entire board. Very helpful on single-layered jelly, ingredients, and candy order levels. Not really helpful on moves levels unless there are blockers. I wished there would be points for Party Booster. However, 4 special candies are created.*
UFO. Very sweet booster. Level 419 is hugely fun. Helpful on all types of levels, but it might depend on ingredients.
Lollipop Hammer. Though undoubtedly weaker than UFO, as it clears only one candy, it is especially helpful to stop seeing "So Close!" messages.
Free Switch. Not so helpful unless you are on an ingredients level, having only 1 ingredient left. The ingredient is sitting just above a candy. It all depends and may not be so effective on other levels unless you are truly close.
Striped Brush. Not very sure what it is, but hopeful to get one. It creates a striped candy of your choice and is activated.*
