Tymon's 1×2×3×3

4D Shape: Hypercuboid

Physical Shape: Cuboid

Pieces: 8 5c, 8 4c, 2 3c

Magnets: 688

Completed: 2024 Jan 24


Over a week after completing the physical 1x2x3x3, Tymon F finished assembling another four 4c pieces and two new 3c pieces that combined with the 1x2x3x3 to create the physical 1x2x3x3 puzzle. This was the last puzzle made with the goal of creating a physical 1x3x3x3.


Legal moves of a layer include normal 2x3x3 90° and 180° twists that rotate pieces without changing their 4d orientation, 4d 180° twists that change the pink/purple stickers, or a combination of both.


Besides basic stickers (white, yellow, orange, red, green, blue) every piece on the puzzle has pink and purple stickers which indicate in which 4d orientation the piece is. In the solved state every piece must have the same 4d axis orientation. The 1x2x3x3 puzzle is much more complicated than smaller hypercuboids, but it can be solved by: orienting 3c pieces in 4d axis, orienting 4c piece in 4d axis, orienting 5c pieces in 4d axis, solving the rest of the puzzle like 3d 2x3x3. Tymon made a YouTube video showing an example solve of the puzzle.
