In your way through the Candy Friends Saga world, you'll encounter levels which contain tricky obstacles known as blockers.
Blockers are objects which you’ll need to either work around or destroy. In some levels they'll be the barrier between you and your goal and in some levels you'll need to clear them completely from the screen, in order to complete the level.
In general, making matches next to them to them will be enough to clear them, however, some will have more than one layer to them so can be quite persistent. With these layered blockers, you may need to make multiple matches to remove several layers before they disappear completely.
Top tip! By combining candies to make special candies, you can really cut through multiple layered blockers with easy. Try using the Striped Candy or the Wrapped Candy and if you can mix the two before triggering them, even better!
