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 1683 is the thirteenth level in Taffy Treetops and the 665th jelly level. To pass this level, you must clear 27 double jelly squares in 18 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The sugar key that opens the bottom part of the board where the jellies are will appear only when there are six moves left, meaning that two-thirds of your moves will be restricted to the top half of the board. It also means you have to clear the remaining nine double jellies in just six moves.
The jellies are worth 54,000 points.[1] Hence, an additional 1,000 points is required to earn one star.
