The Infinity Puzzle ™ is a new type of jigsaw puzzle that tiles continuously. It has no fixed shape, no starting point, and no edges. It can be assembled in thousands of different ways.
Topologically, the Infinite Galaxy Puzzle maps to a real projective plane, an impossible 3D shape where the inside and outside are mathematically indistinguishable. What this means is that it tiles with a flip. Pieces from the one side attach to the other but only after flipping over. Just like a Mobius strip has only one surface, the puzzle has no up or down side. You can start the puzzle anywhere on any side, making it extra challenging. This puzzle is adorned with a photograph of Westerlund 2 from the Hubble telescope. The image is continuous from one side of the surface to the other, so one cannot see the entire photo at once. Explore the galaxy while assembling the puzzle in multiple ways. The puzzle also features special space themed whimsy pieces.
