Cobwebs
Homescapes Guide
What are Cobwebs in Match-3 Elements? These are elements similar to a Chain or a Wall where it prevents you from moving the piece covered by it. However, even if they cannot be moved, you can match a piece to it to have it removed.
Cobwebs can fall to different places as well, so try to clear them fast. You can use Power Ups as well to remove them.
