It is useful to combine a striped candy with a wrapped candy. Vertical striped candies are suggested to be made. Work from the bottom as it may free liquorice locks and clear swirls.
Hopefully, with a good board and some special candies, the ingredients will successfully drop down and fulfill the requirement.
If the first ingredient is not dropped in 8 moves, the second one will always spawn. If both of those are not dropped in the next 8 moves, the third one will spawn. Hence, on your eighth and sixteenth moves, try to make vertical matches in odd numbered columns.
