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 1712 is the twelfth level in Sweet Skies and the 206th mixed mode level (78th jelly-ingredients). To pass this level, you must clear 72 double jelly squares and release 6 gummi dragons in 17 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
