The world of twisty puzzles has reached a new pinnacle with the creation of the 49x49x49 cube, now recognized as the highest-order NxNxN puzzle ever made.
The 49x49x49 3D-printed cube represents a significant leap from its predecessor, Yang Yongshun's 35x35x35 cube (we have very little info about this one), or Matt Bahner's 34x34x34, adding 14 layers—a difference comparable to that between a 7x7x7 and a 21x21x21 cube. The speedcubing community expressed astonishment at the cube's intricate design, with one user noting the challenge of maintaining the stability of the corner pieces. Another member humorously pondered the potential chaos of a piece popping out during a solve.
This development underscores the continuous innovation as puzzle designers and solvers push the boundaries of what is possible.

- Record: The highest order NxNxN twisty puzzle
- Duration: 5 years / 3000 work hours
- Estimated Cost: $1800 materials + $2080 tools & consumables + labor
The cube turns really slowly, so it's not meant to be solved. Even completing the checkerboard pattern took 25 hours to demonstrate that the puzzle is fully functional.

Due to the curvy shape the height of each edge piece is the same
About The Creator
Preston Alden is a mechanical engineering student who has recently completed his major and has already made a significant mark in the world of mechanical puzzles. While he worked on smaller projects in the past, his ambitious 49x49 puzzle served as his grand debut. Preston meticulously planned and developed this intricate project in secret for 5 years, driven by both passion and caution—he didn’t want to reveal it prematurely in case of failure.
Stickering the cube took more than a month, individually supergluing each sticker
After successfully completing the 49x49, Preston began to introduce himself to the cubing community through various forums. This step allowed him to share the process, challenges, and ingenuity behind his work with enthusiasts who appreciate the complexity of such designs. The stickering alone took more than a month to complete.

Virtual Solve
While the physical 49x49x49 cube has just been created, it was first conquered in the digital realm. Four years ago, a skilled solver (s16269) tackled a virtual version of the 49x49x49 cube, completing it in an impressive 3:28:04.463 which is currently listed as an unofficial record. The solve, captured in a timelapse YouTube video, is a testament to both the solver's perseverance and the intricate challenge.
