Level 253 candy crush impossible

Hello @253impossible and welcome to our community.  @53 is designated a hard level but it definitely can be completed.  As @hoffy0331 said - you obviously need to clear the icing blockers in the middle so that the nut can exit.  There are 5 colors available so until you clear some of the blockers it won't be that easy to make combos.  If you have it the coconut wheel is definitely a very useful booster to use to complete the level.  It will roll over three candies creating striped candies in whatever direction you move it and there are already two of them on the board.  The first step is to open the board up, if at all possible (in other words if you have a full space dash or build a bot) use a double CB combo - otherwise try to  start with a CB/wrap combo with the wrap a color of candies that are close/next to some of the blockers and add a coconut wheel if you have it. If you can roll a coconut wheel immediately over a CB, it will create striped candies across the whole playing area as long as there are candies for it to roll over.
The best use of the coconut wheel if it is in the top portion of the board is to use it horizontally to try and destroy some layers of the icing in the middle - otherwise use it vertically up or down the side of all the blockers (depending on its position on the board).  Hopefully while trying to remove the icing you don't activate the two coconut wheels on the board too early where they won't be of any use and the striped candies are in the wrong direction to remove any of the icing.

You can also always google a level you may be stuck on and you will find several videos that may help you in solving the level.

Good luck and Happy Crushing!
