Level 1703 is the third level in Sweet Skies and the 12th mixed mode level (9th jelly-ingredients). To pass this level, you must clear 18 single, 46 double jelly squares and collect 4 cherries in 31 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The presence of five colours makes it easier to make
special candies to clear the cake bombs. Cake bombs block the ingredient
dispenser and the ingredient exits on the left side.
Candy bombs only have five moves. However, they do not spawn very frequently, so they will become more of an annoyance than a challenge. The jellies and ingredients are worth 150,000 points, which is more than the one-star target score. 
This level is all about clearing the cake bombs. Destroying both cake bombs is enough to clear most, if not all of the jelly and bring down the ingredients.
Remove the remaining jellies with special candies.
This is the first mixed level with cake bombs.
Element Spawn Notes
Ingredient spawn density: 1 move
↑ (18 single jellies × 1,000 points per single jelly) + (46 double jellies × 2,000 points per double jelly) + (4 ingredients × 10,000 points per ingredient) = 150,000 points
