There are so many orders required to collect: 10 striped candies and 10 colour bombs. With 12 moves, this is an acute challenge. (Acute definition: present or experienced to a severe or intensive degree, of a difficult or unwelcome situation or phenomenon)
Chocolate would make things worse.
The lucky candies would only be reached by vertical striped candies.
They would also reveal useless striped candies, since they could be created by normal matches.
The player has to detonate at least 3 colour bombs and 3 striped candies per move for ideal chance of completion.
