1. 3D Crystal Puzzle, Saturn

Bepuzzled, Amazon

Bepuzzled's 3D puzzles provide thought-provoking fun in 42 different shapes. We think this translucent Saturn puzzle is out of this world (and many Mental Floss readers seem to agree), but Bepuzzled also offers puzzles in the likeness of birds, animals, fruit, vehicles, and other common objects, in case assembling a noble snowy owl or a bunch of purple grapes is more your speed.

2. 33,600-Piece Wildlife Puzzle

Educa, Amazon

For true puzzle experts, 500- or 1000-piece puzzles are just the warm up. Designed to be one of the world's biggest commercially available puzzles, Educa's wildlife-themed puzzle has a mind-boggling 33,600 pieces and measures almost 19 feet by 5 feet when complete. It's so big that it comes in a suitcase-sized wooden box on wheels for easy transport. (With that many pieces, you may be worried about misplacing one or two, preventing you from fully completing the image, but fear not—Educa has a policy of replacing any individual pieces that go missing from its puzzles.)

3. 1000 Colors Puzzle

Design aficionados will love this CMYK-themed puzzle that features a slightly different color on each piece to create a color gradient. This fan favorite is so popular that it regularly sells out, but it's due back in stock within the next few weeks, and trust us, it's worth the wait.

9. The Infinite Galaxy Puzzle

The Infinite Galaxy Puzzle provides the ultimate puzzle experience: a puzzle you can never truly finish. Featuring a NASA image of the Milky Way’s galactic center, it has no fixed shape or edges, and the pieces are double-sided so that users can flip them and rearrange them in any configuration. "Topologically, the Infinite Galaxy Puzzle maps to a Klein bottle, an impossible 3D shape where the inside and outside are mathematically indistinguishable,” its creators write. "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." There are currently two versions of the puzzle you can work on, in case you get tired of the endless options of the original puzzle and need yet another infinite challenge.
