The most difficult part of this level is the hidden candy bombs. If you handle those, then it can be easy to pass this level. The problem is that there will be so many special candies, but making one combination can easily destroy all special candies on the board.
Mystery candies spawn from the extreme left and extreme right hand side of the board.
The presence of five colours makes it easy to create special candies.
First open up all the bags and hope you have one of the orders all set up and ready to go, and that there are no candy bombs or chocolate that you will not be able to reach. After that, work on the combinations one at a time — they should not be unfamiliar to you by now, and activating one is likely to mess up your setup for others.
