Level 590 is the fifteenth and last level in Gummy Gardens and the 262nd jelly level. To pass this level, you must clear 81 double jelly squares in 17 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The board can be divided in four parts and a single square: The candies that are going to go below, the candies that going to go to the top, the candies that are going to go to the right, and the candies that are going to go to the left.
Make as many special candies as you can using the four parts: if you can make several special candies, choose the combinations who are not in a single part so you can make the special candies that are in a single part after.
