Carpet
Homescapes Guide
What are Carpet Match-3 Elements? This will be one of the beginning obstacles that you'll encounter in the game. You'll see carpets as green fabric looking tiles beneath any piece, power up or other elements.
In order to spread the carpet, you need to match 3 pieces. One piece should be on top of a carpet tile in order for it to spread to the other two, and so on. Carpets can be spread by power ups as well.
