My best tips in addition to those stated are:
On legendary levels I usually find:
If I am on a win streak I may pass first time using all of the starting boosters. If I fail on my first attempt sometimes I pass on my second attempt using all three starting boosters. After that I always fail, even if I play starting boosters. So I recommend that if you don't pass first or second time do not waste any boosters on legendary levels. If the boosters don't help on your first two attempts then you are on a "pay to pass" algorithm, so wait until the game offers you enough extra moves that you can see you will pass with 10 gold. If you are out of gold then keep trying, playing the first move the game suggests, and watch out for a lucky board. How to recognise a lucky board is next:
Lucky Boards are written into the game by King. They help us pass tricky levels, and when they turn up is part of the game design. Many unrated levels will give a player a lucky board on their second attempt, so don't waste your gold or boosters to keep a win streak early on. Some levels the game will give you a lucky board when an offer (train of fishing boat) pops up, often when having just one life left. Sometimes I then pass if I play starting boosters at this point. Legendary and nighmarish levels are hard to predict when they show up.
How to recognise a lucky board:
One way is to watch the YouTube videos, especially Johnny Crush, as they illustrate how to pass difficult levels without boosters and will show you what a lucky board in that level may look like.
If there is an opportunity to create a wrapped or striped candy on your starting board this may be a sign of a lucky board. If not, follow the first move the game suggests and if an opportunity to create a special candy opens up, that may be a lucky board. If a colour bomb or lots of special candies drop, you have a lucky board. Watch out closely for a chance to use these to create combos. In the later levels colour bombs and special candies won't just drop, but there will be opportunities to create them in a lucky board, so watch out for any such opportunity and then for the chance to use these special candies to create a combo. A wrap/colour bomb combo is very powerful and many legendary levels rely on this to pass.
So: Learn to recognise a Lucky Board. Then make sure you that when you spot one you take every opportunity to create those winning combos of special candies the game requires.
If you fail but come very close then play the lollipop needed for the last jelly, for if you don't it may be long time before the next lucky board comes along.
