Level 553 was the eighth level in Charming Carnival and the 251st jelly level in Dreamworld. To pass this level, you must clear 36 double jelly squares in 15 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The mystery candies at the bottom have been replaced by locked 15-move candy bombs, but they pose no threat because bombs that reach zero at the same time you run out of moves don't go off. And even if it did, you have no moves left anyway.
