The Toffee Swirl behaves similarly to the Icing Blocker, but it's affected by gravity. Therefore, if you combine a Candy right underneath, it will fall down. The Toffee Swirl can't be matched, so you will need to dig in with your sharp teeth to make it disappear. Tasty!
It only occupies one of the tiles of the game board. Every time you combine 3 regular candies right next to it or even when you hit the blocker with a Special Candy effect, you will get rid of one of the layers. Keep doing it until you completely get rid of it!
Play Candy Crush Saga and practice how to clear the Toffee Swirl Blocker. Divine!
