The Rubik's Royal Brainteaser is an unusual puzzle touted as a "sequential jigsaw". Aside from the border pieces, it has only a skin-deep resemblance to a traditional jigsaw puzzle. As the pieces are cut alike, the logic that goes into completing the image comes from clues hidden in the pieces themselves. When made correctly, the image will create a single continuous loop of chain studded with gems of various shapes and colors.

While jigsaw puzzles are not typically included in mechanical puzzles, this one has a logic that does not conform to traditional jigsaw puzzles. It is also notable for its connection to the original cube craze.
