Level 1706 is the sixth level in Sweet Skies and the 777th jelly level. To pass this level, you must clear 32 single and 21 double jelly squares in 40 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Try to remove the magic mixers as fast as possible, as not only will they not be able to spawn liquorice swirls, but they also clear a lot of the hard to reach jellies with their explosion.
The ideal item to get from the mystery candies is any special candy but especially jelly fish. They will probably clear off the liquorice swirls or any last jelly squares that may be hard for you to reach.
