Hints and tips showing how to pass level 1688 Candy Crush Saga without boosters by Cookie
Level 1668 is a double task level, you have to clear jelly as well as collect 2 ingredients.
The candies start in the bottom right square, move through the teleports into the top left square, then down to bottom left and finally up to the top right and out of the exits.
So you have to clear all the blockers to get the ingredients down to the exits, but if you work on making combos to clear the jelly you should find that the blockers will be taken care of and the ingredients should find their way down.
Remember to get the ingredients down to the exits you need to work in the top right square once the blockers are gone.
Don't move the ingredients away from the three columns where the teleports are.
