The presence of five colours makes it easy to create special candies.
The jellies are worth 16,000 points. Hence, an additional 79,000 points for two stars and an additional 99,000 points for three stars have to be earned through matching of candies.
Since the double jellies are below the candy bomb dispensers it is inevitable that candy bombs will be dispensed on the jelly squares once the two layer icing are cleared. Coupled with five colours and an open board, it decreases the difficulty of creating colour bomb + candy bomb combinations.
30 moves are limited to earn a huge amount of points due to sugar crush and the limiting of the number of special candies created via regular matches. However, this point is less critical due to the candy bombs which will be endlessly dispensed.
