UPDATE: This thread is outdated! The move count has been increased from 22 to 27, so it is now barely within the realm of possibility to win without extra moves or boosters.
Level 6471: You have 22 moves to bring down all the Sprinks, clear all the licorice swirls, and clear 30 color bombs. The color bomb dispensers give 1 color bomb per move. This means that you have to make 8 additional color bombs in the top and bottom portions.
(Special candies on the board are from timed boosters.)
The only problem? This level has 4 colors. You will never be able to make and detonate 8 extra color bombs while playing perfectly.
Originally, this level had only 2 colors. It was placed at level 6477 before it got moved to level 6471:
There were bombs and only 20 moves, but at least it was possible!
