This level is somewhat hard because 20 striped candies have to be collected in 25 moves. This means an average of one striped candy has to be collected every move. The player can fail the level easily if there are no colour bomb + striped candy combinations which can collect most of the orders that you need.
Waffles reduce the space in creating colour bomb + striped candy combination that is essential in beating this level.
Also, 8-move candy bombs may disrupt your plans in creating the aforementioned combination.
Like most candy order levels requiring tons of striped candies, mixing colour bombs with a striped candy is the best option. However one is usually not enough to help you pass the level. At least 2 of these combinations are needed to complete the orders.
Try to dispose the waffles whenever possible, to increase the space.
Immediately find opportunities to create colour bombs. If a striped candy appears besides a colour bomb, match it with the colour bomb. This can buy you some moves so that you can create a colour bomb + candy bomb combination.
Immediately find opportunities to drop some candy bombs so that you can match the colour bomb with the colour of the candy bomb. This is provided if you have a decent number of moves left, have very few striped candies left to collect and that you can create striped candies within a move or two.
