Tiles are Puzzle level goals that you'll be able to find underneath the other pieces on the Puzzle board.
To collect Tiles, just make a match over them:
or hit them with a Booster such as a Bomb or a Rocket:
Tiles can't be moved and they can be hiding under other board elements such as Boxes or Hay so make sure to pay attention to your Level Goals!
If they are blocked by another obstacle, you'll first need to remove the obstacle before you can start collecting the Tiles. No damage will be done to the Tile when hitting the obstacle:
Similarly to many other Match-3 board elements, Tiles can take more than one match or hit to be completely removed from the board. Pay attention to the Tile's layers and its color:
The brighter color means you will still need two matches or hits to destroy the Tile completely, but if you see the darker-colored layer, it means the Tile is almost broken and needs only one more hit!
