Focus on creating the colour bomb + colour bomb combination first.
On mobile, creating enough special candies to pop all the liquorice shells can be a major problem, due to the limited space available to work with at the beginning. Getting the colour bomb + colour bomb combination is simplest if you can take advantage of the 3 liquorice shells in the centre column. If you create a striped candy, try to set it off between two liquorice shells, aligned to hit them.
Try to match some of the wrapped candies you create with colour bombs—that clears two colours from the board and makes it MUCH easier to get more wrapped candies.
Finally, meeting the orders alone may not give the player enough points to pass the level. Hence, check the number of points at all times and if necessary, create more colour bombs.
