What is a Super Sugar Crush?

I just got it on level 3,482.  It’s been happening a lot lately on easy and hard levels.  Seems to happen when I win on the last move.

I just discovered this feature, and I like it!  I waited until the final turn to clear the level (on four different levels, so my assumption is that it will work for all of them).  When I finished, I received the message "Super Sugar Crush", and then received a nice benefit -- party hats blew away all pieces on the board, allowing me to collect all sugar drops that were available to redeem. If you're trying to maximize your sugar drops, it's definitely worthwhile to wait until the final turn to win. 

Hi Linda, thanks for the print screen.  I have to ask the members of my Facebook group if they ever saw this.  If you can double up then that's pretty cool.  By the way if any of you would like to join my Facebook group here is the link.

I just had it happen on level 664  I finished the level on the last move  

It happens when you finish a level with 0 moves remaining. Some party things appear, and the entire board is cleared, however, you don't get any special candy and score unlike the normal Sugar Crush because you have no moves.
