Completing Candy Crush Level 21 is all about having the right plan of attack. If you run into this one with guns blazing, your probably not going to be successful. The 45 moves that you are given go quick and 1 or 2 moves could be the difference in your victory or defeat.
With this said, candy crush level 21 is the first level with triple layered Jelly or “Meringue”. The physics of the meringue is slightly different then the other 2 layers as well. You can get a match up right next to the 3rd layer and it will break 1 layer of the jelly. Otherwise, you have to be “ON” the jelly to break it when you do a basic match up.
Best way to get through Candy Crush Level 21 is by focusing on the corner jelly’s first, as they will probably be the last Jelly you still have on the board. This will help you open up the board and knock out the rest of the jelly. The best solution for this is a wrapped candy/striped candy right in the center of all the jelly. This will clear most of it with a few stragglers left behind. At this point, you should be able to get through the level without trouble.
