The presence of four colours makes it easy to create special candies. However, it is not too useful due to the board layout.
The jellies are worth 18,000 points. Hence, an additional 82,000 points for two stars and an additional 132,000 points for three stars have to be earned through matching of candies.
The area where the jellies are located are not connected to the main board. This makes individual horizontal striped candies and wrapped candies useless as they cannot go into that area. Finally, huge point cascades are difficult as the jellies are only on a single row.
There is a liquorice locks on the row where the jellies are, requiring some moves to clear them. Once that is cleared, the chocolate will spread. This forces more moves to be spent to clear them and the jellies.
With respect to the two and three star target scores, 25 moves are insufficient to boost the score by a huge amount of points to meet those target scores.
With only 25 moves available, Sugar Crush is almost worthless with respect to the two and three star target scores. Hence, try to create as many special candies as possible as they are worth many more points.
Due to the difficulty of creating huge point cascades, use colour bombs on the candies which have jellies underneath them to earn a huge amount of points.
