This level is currently nearly impossible to beat without boosters (or even with boosters). This is likely caused by a level buff, lack of moves, an objective which requires insane luck to fulfill, a level glitch, or a design error. This level is currently, or likely one of the hardest levels of the game.
Level 4973 is the third level in Wrecky Workshops and the 963rd mixed mode level (632nd jelly-ingredients). To pass this level, you must clear 12 single, 25 double jelly squares and release 12 gummi dragons in 17 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
