2018-02-11: Maarten van der Velde wrote an eMail to me, describing his website.

Paper cutting SOMA.
A very nice homepage, showing many ways of folding boxes, decorations, games...
Well, you'd better see for yourself.
The fantastic thing about this page is that you may change dimensions of the things to fold.
And then printout these shapes directly on your printer

And then of course that there is also a foldable SOMA description.

2016-12-27: Jean-Christophe Beumier has made a nice homepage Un cube nomm Soma, illustrating some SOMA puzzles for you to assemble.
Here: It's in French, but the figures are just as usable for any language of the Earth.

The figures are shown using the height principle, described as the "Pyramid notation" here:


Aaron Son's Titanium SOMA.
Today 14-09-2016 The SOMA puzzle is appearing in a very special version.
Aaron Son has started a Kickstarter project with the intent of manufacturing a series of SOMA puzzles all made in precious Titaneum metal.
The first version is shown here.

Check out Aaron's Kickstarter web pages on this link:

It is a really pretty puzzle, and the Kickstarter page also show a wonderfull amount of nice pictures and videos.

SOMA in a new APP
From John Niss Hansen <> I now (2016-09-05) received information about a new -upcoming- software.
The Software / App is intended for more than one type of puzzles, with SOMA being one of them.
An interesting twist is that this software will allow you to solve the SOMA-cube in a 4 Dimensional version
The App is both for manual and interaktive solving upto 4 dimensions.
Automatic solving of the SOMA cube takes a few seconds for all solutions.
The App is written in APL under Windows, and the possibility for transport to a tablet is being investigated.

In the 4D version of SOMA the box would be 3x3x3x3 and the pieces be the usual ones, exept using 3 sets.
A large number of solutions can be made by taking 3 casual normal SOMA solutions and place them along the 4'th dimension.
Actually more than the usual 240 solutions from each 3D box are possible because the 2 chirale pieces of SOMA will now be congruent and not necessarily mirror images.

Pieces are layed by first selecting the piece from the list, and move it around the possible positions in the box.
The piece is successively fixed by pointing to the places where it should touch.
So - you do not have to manually turn the piece.

The numbers to the right of the unused pieces indicatehow many ways the piece can be positioned in the remaining free space.
The small "Lamp" is green when a solution is possible, "Red" when it is not, and "Black" when the software is indecisive.

My good friend Courtney McFarren (of Ohio. U.S.A.)
The original author of a brilliant solution finder program.
Courtney made some 798 figures. He and I have made the SOLVE figure editing and solution finder program.
Ross Channing
From Canberra, Australia is presenting a Windows compatible SOMA program (somasolver) on his homepage. This is a pretty program, It allows you to interactively enter a Soma shape and solve it. Operating is 3D it gives an extremely nice image, but currently it will not save nor load any figure files.

It seems that I have lost contact with Ross, and that his page is no longer active. The links don't work).
So I have taken the liberty of posting Ross SOMA solver on my Newsletter page.
Newsletter 2010.02.18 "SOMA Solver from Ross."
I just found a Turkish App on the Google Play store. They write:
"Soma Cubes is one of most brain burning 3D puzzle games invented by Piet Hein in 1933 and its roots go back to Pentomino puzzles in which the player attempts to construct 2D shapes bu using the shapes looking like alphabet and each consisting of congruent squares, connected along their edges.
Purpose of this game is to construct a specified 3D shape by using various combinations of given 7 different 3D pieces"

Seldom do we see a new SOMA program, Here we even have one that can be used directly on the web. - fantastic.
The user interface is unfortunately NOT straight forward, and the placement of the pieces is difficult. But never the less, give it a try, as this is the right direction to go.

12 sep. 2011 i've got these links from Darian Jenkins who writes.
Two days ago I found the solver I have spent years looking for. It lets you define any search volume and any piece set. It is easy to understand and use and is in java (works on any platform). You can define 27 or 54 cube volumes and than define the seven piece Soma set and see if the figure is solvable. You can do this all on line without downloading anything! Its on the lower left here:

Except for speed, I think it compares well with this Mr. Keiichiro's unpublished solver:

Check my Newsletter about this great puzzle:

DBOX is available in the biggest store on the planet "Amazon" at the retail price of $19.95
Unfortunately - Currently, Amazon does not ship toys outside the USA, but hopefully that will change, or maybe an outside-US dealer will be found for this great toy.

SOMA is a great game. But many puzzlers also enjoy other kinds of games. Mr. Dan Klarskov is one such enthusiastic person - His interest lies in flat (2D) puzzles. He produce these with a marvellous finish.
For the characters he use 10mm hardwood: Hard maple for cream color, Cherry, and dark American walnut are brown. They are polished with fine grain sandpaper and treated with natural oil on the surfaces. The framework is in 6mm dark walnut laminate and a 3mm base. Polished soft at the underside so that it does not scratch the table.
Visit his homepage to see the pretty games.
The game "PentoZoo step game" is a redevelopment of the French game "Katamino" from 1992. Note that the 12 pentominoes can make 4,5,6,7,8,9,10,11 and 12 x5 square puzzles.
Mr. Klarskov is very interested in this kind of stepwize puzzles, and he has developed 3 other games.
See also the the "MiniHex step game".
All his games are made by a "Jigsaw". The quality is the main issue, so each handmade game is a prime craftwork - The price of course is following this, but 500 DKK (67 Euro)(89$) is in my opinion a very fair price for these pretty games.
By the way - The "PentoZoo step game" is a succes for children even down to the age of 4-6. with an adult close by, of course.

Daniel Tebbutt have produced a simply marvellous program, to solve the "Bedlam cube", try it out from his homepage.
Daniel stated (nov.24.2003) about the program, that "It's not very versatile, nor is it particularly fast (it averages a little less than 1 second per solution on a P4 2GHz, compared with 6 solutions per second for my C implementation), but it is written as a Java applet and it is nice and graphical (I spent about twice as long on the graphics as I did on the algorithm)."
I (Thorleif) disagree, it's a really fine program.
The sourcecode is even available.!
For the record, if you click 'next' 19,186 times, it will find each solution once, and only once.
