It is not the number of moves, but also the bubble gum layers and the number of layers of the liquorice curls. Evidently this is a profitable strategy for King. As long as people keep paying for winning they will continue to create this silly levels.
It is not even luck... it is about frustrating people so that they pay to move through impossible levels... it seems like it is working for them as they've done this for some time while reducing free boosters and free moves at the same time. Boring and pathetic.
