Hints and tips showing how to pass level 425 Candy Crush Saga without boosters by Cookie Level 425 is classified as a hard level so you can expect to lose a few lives before you pass it. You will need to be able to make wrapped candies, which a lot of people struggle with.
Forget about the blue candies to begin with and concentrate on making your stripe/wrap combos. Making the combos will keep the bombs under control while you are working towards your goal of collecting five stripe/wrap combos. The blue candies will almost take care of themselves if you work on the other orders. If you get a colour bomb use it on another colour, not blue. If you clear all the blues you will have to wait a few moves for more to fall, but if you clear a different colour more blues will fall down for you to collect. You can use a colour bomb to remove a candy that is keeping your combos apart too. Video below.
