Level 531 is the first level in Sticky Savannah and the 231st jelly level. To pass this level, you must clear 10 single and 44 double jelly squares in 25 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Remove the marmalade covering the colour bomb first, then use it on a colour that will unlock the liquorice locks on top.
Afterwards, clear all the jellies. The conveyor belt will shift all candies by one square left after each move, so try to take advantage of them. The sides and upper corners are a bit tricky, but it is not something that players have not dealt with at all.
