Level 524 is the ninth level in Sour Salon and the 168th jelly level. To pass this level, you must clear 54 double jelly squares in 21 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Bubblegum pops on the bottom left and toffee swirl on the bottom right make their boards inaccessible. Double jellies are underneath every one of those blockers.
