If you pursue a good strategy, this level is not as hard as it looks nor as hard as some commentators suggest. Still, it is hard, perhaps even very hard and comes as a bit of a shock at the end of a fairly straightforward episode.
The trick is to clear plenty of space with colour bombs, wrapped candies and striped candies before attempting to make the striped/striped combinations. Of course, if one of the required combinations lands on your lap early, then take it. But when there is no obvious or immediate striped/striped, better you choose to go for maximum chocolate destruction early rather than striving for those striped/striped orders. Wrapped candies are your most likely good friend for locked chocolate destruction.
With a bit of luck, you will still have 25 to 30 moves remaining once the board is mostly open (does not need to be completely open) and with luck you might only have four combinations still to get. At that point, work relentlessly for the striped/striped combinations. This is challenging but only somewhat hard at this stage.
Tastes as sweet as honey when you finish the level and thus the episode.
