  A DICE SOMA - is it possible ?
In a Newsletter you may read about a spotted SOMA, and our complex search for the solution.
But today (2018.04.11), my friend Volker Latussek asked a similar question - that I will pass on to you all.
I am sure it will keep you sleepless for many weeks to come.
Imagine a SOMA set of 7 pieces.   3 pieces are colored blue,   4 are white.
      "Your task - should you choose to accept it"
Is to assemble a DICE-cube where each of the 6 sides have 9 "eye" fields.
One side has 1 blue field, another 2 blue, then 3, 4, 5, and 6 blue fields.
And of course, just like a playing dice, the sum of blue fields on opposing sides is 7.
Is it possible. ??? ?? ? .... Yes it is. but for now - I will keep Volker's solution a secret.
It will eventually be revealed on this website.

  A new figure collection
In december 2017 Tim Fielding added a collection of 200 SOMA puzzles, as well as a
complete set of figure drawings. And them Tim even made this pretty poster.
Try moving your mouse over the poster.

You may jump directly to the first page of these figures Here.

In the SOMA Addict Newsletter 1999.01.18 Vol.2 No.1 page.2 Right side column (page 10 in the PDF file) we can read:
"Finally, since some SOMA Addicts may well also be error-counters, we also acknowledge that the first edition
of the Parker Brothers SOMA Booklet contained a counting-sketching error in the SAM'S SITTING DOG figure.
That error IS the only way one can identify that presumably VERY VALUABLE first-edition booklet."

OOH: - An identifiable "First-edition" sound very interesting - but...... Being "valuable" indicates that it must be quite rare.
Checking ALL my versions of the Parker booklets, show that I do NOT have that version.
SO - If anyone has the Parker SOMA Booklet with a counting error in "Sam's sitting dog" - probably on page 19
Then I would very much ask for either a Color scan of the booklet, or permission to borrow it so that I can make the scans.

HELP:   In Newsletter 2008.04.27 we work on a special "Spotted SOMA".
We have found possible solutions, but we are missing historic facts.
"IF" You know anything about this spotted version of the SOMA puzzle,
then please contact me on mail. Anything about this version is appreciated.

  A series of questions are asked in the following Newsletters. IF you know anything, then please write to me.
N2008.04.27 "The Spotted SOMA" - - A solution has been found, but we need historic info.
N1998.12.01 "SOMA Alternatives (Checkered, Couples, Balancing)"
N2016.07.07 "SOMA can start with small children."
N2016.07.09 "Apparently correct figures."
N2016.07.10 "Distribution of SOMA solutions."
N2012.04.02 "Parity and Symmetry" - - The puzzle question from 2012/01 has been solved.
Puzzles         "V076100" and "V101125" The figures V095 - V122 had no solutions, but on (2017.08.06 Bob Nungester has sendt the solutions [V118 seem impossible]).
                      By 2018.03.15 Robert Staatz suggest using 2 hidden cubes to make V118.
N2010.02.18 "Ross SOMA Solver." Contact is lost to Ross. I am looking for someone that can make a similar Solver for Online web use.

  What is SOMA ?
  Problems worthy of attack, Prove their worth by hitting back. (Piet Hein)
From time to time, man have tried to construct a threedimensional puzzle.
In no circumstances has it, succeeded so well as with the SOMA cube, invented by the Danish Author Piet Hein.

    If you recognize this, Then you know the power of SOMA.
If you don't - then read this web site.

Having the seven Soma pieces in hand, first try to form the infamous 3x3x3 cube. There are 240 independent ways of making this cube.
Aside from cubes, there are thousands of geometric shapes that can be created from the seven simple Soma pieces.
Within these Figure pages, there are many figures (ALL that I know actually) which can be built using the SOMA pieces.
Some of the figures will require your imagination to figure out where unseen cubes or holes belong.
When you have succeeded in making figures from these pages, try to develop some of your own.

And if you have any new figures, then please let me know.

The video is also available on YouTube: -   "SOMA CUBE ANIMATION (12 figures, 3D puzzle solution)".

For many years the descriptions and drawings were the way
we saw the SOMA puzzle.
Now however, Ronald Deckert and his friends at
have created the most beautifull video of the SOMA puzzle.
So. It's only to say - enjoy the video and the music.
Do notice the 3 new figures - "Lion", "Elephant" and "Airplane" .

By the way, Ronald also made a really pretty strategy game called Dr.D.
Now the description is in German, but if you don't read that, then ask Google to translate.

  WHO are YOU ????????????
This homepage is a place for people with some (short or long) interest in 3D puzzles.
My hit counter show that this SOMA page have around 5 hits per day. So - YOU - who are reading this.
Please send an Email to me at
Tell me "Who you are", "Where you live" and "how You use SOMA"
Obs: The SOMA users world map is NO longer updated.
Message to you all:
Any letter or Email you send to me, will be answered quickly. However I am slow (Very slow... like molassas in winter)
to get anything put on my web pages.
The reason? well - being a college teacher in mathematics, electronics and technology require a huge effort in reading, preparing etc.
so... the SOMA page comes second.

Enjoy your puzzling - with friendly wishes: Thorleif.
