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 790 is the fifth level in Fudge Fjord and the 175th mixed mode level (114th jelly-order). To pass this level, you must clear 169 single, 16 double jelly squares, collect 13 yellow candies and 72 toffee swirl layers in 20 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
