Avoid having the ingredients to be on top of the icing. It is recommended to make vertical striped candies as they will clear the columns where the ingredients are and pass the level more easily. Wrapped candies are also highly recommended as the board is small.
There is no difficulty in getting two and three stars as the two and three star target scores are only 8,000 points and 20,000 points respectively. The ingredients are worth 20,000 points, which is more than the two star score requirement and is equal to the three star score requirement.
