Make as many colour bombs as you can in the initial screen. Chances are you can make at least one or two out of red candies, if they do not cascade as the candies settle.
Make as many striped candies as you can, trying to get one adjacent to a colour bomb (preferably above or below it). while keeping an eye on the candy bombs, and matching them if needed. Use a colour bomb to remove the candy bombs, only as a last resort.
As soon as you have a striped candy + colour bomb combination set up, do the following:
One by one, detonate any other colour bombs on the screen, by carefully matching them with a regular candy of a different colour than the striped candy you have ready to combine. Take care not to disturb the alignment of your combination. This will increase the number of candies matching that striped candy, for use in the next step.
Now, take the striped candy + colour bomb combination. This should bring you close to completing your order
In the few moves that remain, pay close attention to the number of red candies on the board at every turn, optimising how you match them in order to collect as many as possible.
