What are Chain Match-3 Elements? As you progress through the levels, you will encounter pieces that are covered in golden chains. These chains prevent the said piece to move, and they are stuck in their spot.

In order to break the chain, you'll have to match at least 2 pieces of the same color to a chained piece. Boosters such as rockets, bombs, planes, and the rainbow ball can also destroy this. There will be cases as well other elements can be chained and they can only be removed using power ups.
