Make a Soma Cube Out of Sonobe Modules

A soma cube is a puzzle made out of seven different shapes and must be assembled to form a 3 x 3 x 3 cube. To make a soma cube out of sonobe modules, you will need 122 units. Yes, 122.

(Click here to learn how to make a sonobe module.) 

The Seven Pieces (they don’t have to have different colors):

Piece 1, or “V”: 14 sonobe modules

Piece 2, or “L”: 18 sonobe modules

Piece 3, or “T”: 18 sonobe modules


Piece 4, or “Z”: 18 sonobe modules

Piece 5, or “A”: 18 sonobe modules (Don’t ask me why it’s “A” / “B” / “P”)

Piece 6, or “B”: 18 sonobe modules

Piece 7, or “P”: 18 sonobe modules


Making the pieces:

The same rule applies as the 12-unit sonobe ball tutorial: tuck the flaps into the pockets. What I noticed, though, is I get better results if I don’t “pre-fold” the sonobe module like this:

Rather, fold only where it is needed.


Once you’re done with the seven shapes, you can now form them into a cube! There are more than 200 solutions so get crackin’!

    Hello, I’m having a bit of trouble actually making the first shape! How do you join the cubes together?

    What size paper do you recommend for the 3 x 3 x 3 cube? Thanks!

      I don’t have it with me right now but the final product is about 5″ x 5″ x 5″. The paper used was 3″ x 3″. If you want to make a bigger cube, then use bigger paper. I highly recommend getting a stiffer paper though, but not stock card thick. Maybe around 120gsm?
