Level 1917 is the seventh level in Praline Pavilion and the 56th mixed mode level (54th jelly-ingredients). To pass this level, you must clear 18 single, 53 double jelly squares and collect 8 cherries in 23 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
This is a redundant mixed level. The ingredients are in sugar chests above ingredient exits and the keys are always placed on jelly squares so it's impossible to clear all the jelly before the ingredients are collected.
