Do not focus on the candy bombs as they have 15 moves and are likely to be cleared before exploding. Try to mix colour bombs with wrapped candy rather than with striped or another colour bomb. The latter destroys the other colour bombs.
Also, many candies can be destroyed, leading to more orders collected and more red, blue, orange candies appearing.
It is also better not to clear the left isolated column prematurely, as bombs will overwhelm it, and make it very hard to break them, which may cause you to fail.
The presence of five colours makes it easy to create special candies.
The orders give 36,000 points (360 regular candies × 100 points per regular candy = 36,000 points). Hence, an additional 264,000 points for two stars and an additional 464,000 points for three stars have to be earned through matching of candies.
40 moves are more than sufficient to create at least a colour bomb especially when the board only has five colours. Furthermore, there are colour bombs on the board.
The need to destroy candy bombs will drastically increase the score as each candy bomb destroyed is worth 3,000 points. The score is drastically increased if a colour bomb destroys them and is essential if the player wants to survive the level.
The candy bombs spawn indefinitely, giving players many opportunities to create colour bomb + candy bomb combinations.
