Strategy[]
Once the board is a bit more open, there is plenty of room for wrapped candy manufacture.
You will get some colour bombs whether you want them or not; think about detonating those on a colour best placed to help you make wrapped candies - that is not always the most prolific colour but the colour whose absence will result in the most concentration for another/several other colours.
A colour bomb + wrapped combination might well cascade into making some more wrapped candies (and stripes). But once you are close to your striped order, colour bomb + striped is comparatively unhelpful for wrapped making - better to go colour bomb solo.
Relatively straightforward stuff if you follow these tips unless you get an unlucky board.
