Level 667 is the second level in Crunchy Courtyard and the 203rd jelly level. To pass this level, you must clear 72 double jelly squares in 20 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Chocolate fountains spawn more chocolate even if all of the initial chocolate has been cleared, and this may block the flow of candies into the lower jellies and make them hard to clear.
Toffee swirls may fall into the lower jellies, adding to the problem of clearing the lower jellies.
20 moves is clearly not enough to clear the jellies.
