Focus on clearing liquorice locks before the moon struck and then try to create as many special candies as possible. Try to aim for large cascades, but be careful about the moon scale.
It is also very helpful to make colour bombs, but make sure not to activate them in the game as they will activate automatically at the end of the game during Sugar Crush. This gives you huge points in the Sugar Crush.
For unknown reasons, the target score for mobile versions is different depending on systems. On iOS, the target score is very low, with 1-star score being 40,000 points. However the Android devices have the score requirement much higher, being 160,000 points. Unlike on the web version, candies have different behaviours on mobile. Furthermore, the moon struck is much less powerful, resulting in less points, which causes the player to easily fail to meet the target score requirement.
