Level 143 is the third level in Gingerbread Glade and the 59th jelly level. To pass this level, you must clear 36 single and 16 double jelly squares in 30 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The striped candies provided can help you clear the chocolate on the lower right. However, they are isolated, and chocolate may grow back if not taken care of.
There is also chocolate in marmalade that requires them to be uncovered before they can be chipped off.
