Level 449 is the ninth level in Butterscotch Boulders and the 194th jelly level. To pass this level, you must clear 52 single and 19 double jelly squares in 25 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The placement of liquorice locks limits you to very few moves at first. Plus, the chocolate will easily dominate the lower part of the board in most cases before you have a chance of getting rid of it.
The bottom left and right corners sport one double jelly each which are very difficult to reach.
Make as many colour bombs as you can, as they are extremely helpful. The colour bomb in the middle should be used with a striped candy for its most helpful effect, hopefully clearing the corner jellies of one layer, if not two.
Destroy the chocolate as quickly as you can as you need to reach the jellies at the bottom of the main board.
Use combinations to clear the rest of the jelly and the corners, although this is not as easy as it sounds.
