Shrinking Soma is a 7-piece expert-level anti-slide packing puzzle designed by Dr. Volker Latussek. Using standard Soma Cube pieces, you must fill a 4x4x4 space so the opening is sealed and the structure won't shift when shaken. Difficulty: Expert. Solve time: 4+ hours. Trains: Creativity.
Best for: experienced puzzle solvers who have already conquered standard Soma Cubes and want a structural challenge that adds a physics constraint to a familiar format.
Specs at a Glance: 7 pieces + 1 box | Expert | 4+ hrs solve time | Trains: Creativity.
The Concept
Shrinking Soma is a brilliant idea by Dr. Volker Latussek. Using standard Soma Cube pieces, create a structure that will fill a 4x4x4 space.
To solve the puzzle, 2 conditions must be met: first, the opening needs to be completely filled. Second, if you shake the puzzle to the sides, the structure must not fall apart.
This limitation creates a peculiar experience for a seemingly simple problem. Harder than it looks!
Size: 65mm x 65mm x 65mm
What Makes It Different
Most packing puzzles ask one question: does it fit? Shrinking Soma asks two at once. You need complete coverage of the opening AND a structure stable enough to survive shaking. That dual-condition requirement makes brute-force trial and error close to useless. You have to think about weight distribution, piece orientation, and structural integrity simultaneously - not just whether the geometry works out on paper. That changes everything about how you approach the solve.
Frequently Asked Questions
How hard is Shrinking Soma?
Expert level - rated 4+ hours. The dual-condition requirement (seal the opening AND prevent sliding) makes it significantly harder than typical 7-piece packing puzzles.
What is the Soma Cube format?
Soma Cube pieces are irregular 3D shapes made from unit cubes. Shrinking Soma uses these familiar pieces in an unfamiliar challenge: packing them so the result is structurally stable, not just geometrically complete.
Is Shrinking Soma a good gift for a puzzle expert?
Yes - it's one of the most conceptually inventive puzzles in the Greg Puzzles catalog, ideal for solvers who want something beyond a standard packing challenge.

FAQ
Do You Ship Worldwide?
Yes. I ship anywhere. Orders typically arrive in 1-3 weeks depending on your location and how customs is behaving.
How Long Does Processing Take?
Some puzzles are produced on demand in our studio in Czech Republic. Processing usually takes 3-5 days before your order ships. During busier seasons it may take a bit longer.
Do Puzzles Come With Solutions?
Usually not. Sometimes you can find the solution on my YouTube channel. If not, feel free to reach out for hints!
What If I Get Stuck?
Good. That's the whole point.
But if "stuck" turns into "frustrated and not having fun anymore," email me. I'll send you a hint if you want a nudge. No judgment. Some puzzles took me days. A few took weeks. Some took months. Some took years. And some I have never solved - and that is part of the appeal.
Returns & Exchanges
Yes. You have 30 days. If the puzzle isn't right for you, send it back in the condition you got it and I'll refund you. If something arrived damaged or wrong, tell me and I'll fix it. Please be patient as we're a small team!
Are These Good Gifts?
People LOVE buying our puzzles as gifts. They're physical, they last forever, they don't need batteries, and they create a real moment - the person sits down, struggles, laughs, eventually solves it. That memory sticks.
If you're gifting, check the difficulty rating and pick something one notch below what you think the person can handle. Easier than you'd guess is usually the right call.
How Are the Puzzles Made?
All the puzzles are made with the help of my partner Puzzle Guy and his 3D printing studio in Czech Republic.
What Is a TIC Puzzle?
TIC stands for Turning Interlocking Cubes. They're a family of puzzles where wooden pieces interlock and rotate into a cube shape. The solve isn't just sliding pieces - you have to find the right rotations, in the right order. They're some of my favorite puzzles in the store.
Why Is Everything Turquoise?
I grew up near the sea in Israel. When life got loud or overwhelming, that's where I went to reset. Sit, watch the water, breathe. Things would settle.
The turquoise on this site isn't a branding choice I picked from a swatch. It's that color. The one I still see when I close my eyes and think of the place that calmed me down. I want you to feel a small version of that when you pick up a puzzle - a quiet moment, hands busy, head clear.
