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 1685 is the fifteenth and last level in Taffy Treetops and the 425th ingredients level. To pass this level, you must release 4 gummi dragons in 15 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
