Level 338 is the third level in Pearly White Plains and the 29th mixed mode level (29th jelly-order). To pass this level, you must clear 25 double jelly squares and collect 50 green candies in 16 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The five-layered bubblegum pops have jellies underneath them and technically must be cleared. However, they can get moved by the conveyor belt.
The bubblegum pops can pose a major problem coupled with the fact there are only 25 spaces.
Collecting 50 green candies is hard with only 16 moves provided, especially when there is a small board and the player has to focus on the jellies at the same time.
