SOMA Library (ZIPdate.2020.12.05) 

Creating puzzles from figure ideas or checking if a certain idea is feasible.
Then we need a program that will solve any SOMA figure. With the DblSoma program we can solve any figure upto 14 puzzle pieces (2 complete SOMA sets) Also add the "FindUnique" program to check the count of unique solutions to your new figure. 
Playing with a SOMA+Plus set can sometimes also need to be solved electronically The SomaPlus program will allow the use of all 11 pieces. 
After having found your own wonderfull figure, the question often arises  "Is my figure
new, or does it exist within the collection of over "5000 figures" The SomaComp will allow you to check your figure's against the entire colection. to compare with all existing figures 

The DblSoma program ZIP file. The FindUnique program ZIP file. Utility program Just extract the ZIP into it's own folder and run the programs. 
The SomaPlus program ZIP file. Extract the ZIP into it's own folder (or into the same as the other programs). 
The SOMAcompare program ZIP file. Extract the ZIP into it's own folder (or with the other programs). The SOMA compare Library ZIP (ZIP'ed at 2020.12.05) The library hold all current figure .HTM files. (Unzip in same folder as SomaComp)

These wonderfull programs are 'almost' intuitive.
However, here is a user manual to them all, by Bob Nungester: Read it here: Bob's SOMA program Manual jun2021.pdf 
These programs are made privately by Bob, and not by a Microsoft registered compagny. If you get a blue message box like "Windows protected your PC", and a button saying [Don't Run] Then click on the link "More informations" (1) and select [Run anyway] (2) This will tell Windows 10 that the program is ok, and Win10 will remember your approval. In some cases, it may help to run the programs as Administrator. Often the first time is enough, but if not then select the Win Explorer  Properties  Compatibility, and select "Run this program as administrator" We do know that some users will fear viruses. But this is the way Windows work, when private people try to share programs. Pr.202006 
[to Top] The Double SOMA solver

Solving SOMA puzzles has upto now been performed, either by making the puzzle by hand (The REAL game), or by some solving program. (ie. The Australian Ross SOMA Solver program.)
DblSoma: For Windows fans, one of the best solvers has now been improved considerably.
PS: Note that:
2017.09.01
Bob Nungester has now revisited his SOMA solver programs.
Originally Bob had a SOMA solver, a solver for doubleSOMA, and a program to help me managing the huge
amount of solutions on these SOMA pages.
However this time Bob took the Double solver, and expanded it so that this single program will now
solve figures ranging from one single SOMA piece upto the 14 pieces found in two complete SOMA puzzles.
At the same time Bob enhanced the user interface to handle the selection of these pieces
I think you will find most of the program functions quite intuitive.
You either load a figure file or start entering your own idea.
The entry is done by clicking in the lefthand field. It defaults to level 1 (the bottom layer)
you then click on the next level button to enter the next level. You will notice that the lower levels appear as shadows in your field
thereby making it much easier to place the next cubes in the right spot.
Having done your design, press [Solve] to see if it is solvable. And then "Do NOT forget to save your solution.
Many great figures have been lost because the puzzler forgot to make a note of it."
Once the solution is complete you can cycle through the pieces to display each one individually in the wireframe model.
2020.12.05 If you use the "Find all solutions" option. Then all solutions of your figure will be written to a file named Solutions.htm
Thereafter you will get a solution information.
Example:
Example of the "Find all solutions"The solution information box states:
4 solutions were written to the Solutions.htm file.
With 2 symmetries the number of unique solutions is 2.
And the file Solutions.htm contain the 4 possible solutions
The saved solution file:
/SOMA001 ;My 2 boxes /...A./...AA /.TZZ./.ZZPA /.T.P./.T.PP /VTB../VVB.. /LBB../LLL..
This image is from the version 2.1
Back in jan.2000 Bob Nungester of Cupertino (California, USA) got interested in SOMA again.
By digging out his Cube from the 1960's, and adding graphics to his old 1980
Apple II program. Bob has written a new Visual Basic 6 Solver program.
The programs uses recursive piece placement with an Island and Parity checking method.
The programs supports the .HTM file format of this Web site.
If you want to know more, then this is The creation story of WINSOMA.
Ps: Bob also examined some of the stranger figures, and Bob's 9 tall Hexominoes. are here.
Some of the Unsolvable Nonominoes may even be solved at double hight using two SOMA sets in
The Double Nonominoes.
2021.06.11
Bob Nungester made an interesting addition to the two solvers DblSoma 2,5 and SomaPlus 2,3
These programs now support the "Twisting" method found by Bob Allen in 2000
Twisting is a strange thing, but mathematically explainable  check it out in the Newsletter 2000.02.09.
[to Top] The Find Unique utility

FindUnique:
DblSoma will allow you to save a "Solutions.htm" file that contain 'ALL' possible ways to solve your figure.
(You may rename that file later if you want)
However in many figures, there are symmetries and rotations of pieces. Such solutions are normally considered to be identical.
And they do not count in the number of different ways a figure can be made.
This of course is logical, but the problem is to find out, how many of all the possible ways that are really different from each other.
The FindUnique is an additional function to the SblSoma program, that will scan all possible combinations in your figure file.
The file you get when you 'Tick' the "Find all solutions and..." in the DblSoma program.
It will check rotations and mirroring etc.
and then output a new file, using the same filename, but with "Unique" in the front. ie."UniqueSolutions.htm"
[to Top] The SOMA+Plus solver

So the answer to your question  Where can I buy SOMA+Plus ? 
[to Top] The SOMA Compare program

What it does.
But Unfortunately I do not post individual figures anymore. The time it took to handle became too much. The collection has become so big, that the purpose of adding new figures seem endless.Now  back to the SomaCompare program:
Though, of course, if I receive figures that are especially pretty. Or show some property (like folding options, and such) then there may be the odd figure that will be added.
In a few cases of interesting new discoveries where the puzzler he/she agree to write some text that I can use on the web. Then this can be used.
But, I regret, my time to update the SOMA website has become more limited the latest years (We now have december 2020).
This program will check files for duplicate Soma figures. The interface allows the user to select one file and then
the program checks all other files in the same directory against each figure in the selected file.
It works for any figure size up to 54 cubes.
It checks each of the 48 possible orientations (same as symmetries) The symmetry number listed for each figure
shows the transformation that will make the duplicate figure the same as this figure.
Each symmetry maps points from X, Y, Z to some other value. For example, a 90 degree clockwise rotation about the X axis maps each X, Y, Z to X, Z, Y (symmetry #11). Listed below are the 48 symmetries:
1 X, Y, Z 9 X, Z, Y 17 Y, X, Z 25 Y, Z, X 33 Z, X, Y 41 Z, Y, X 2 X, Y,Z 10 X, Z,Y 18 Y, X,Z 26 Y, Z,X 34 Z, X,Y 42 Z, Y,X 3 X,Y, Z 11 X,Z, Y 19 Y,X, Z 27 Y,Z, X 35 Z,X, Y 43 Z,Y, X 4 X,Y,Z 12 X,Z,Y 20 Y,X,Z 28 Y,Z,X 36 Z,X,Y 44 Z,Y,X 5 X, Y, Z 13 X, Z, Y 21 Y, X, Z 29 Y, Z, X 37 Z, X, Y 45 Z, Y, X 6 X, Y,Z 14 X, Z,Y 22 Y, X,Z 30 Y, Z,X 38 Z, X,Y 46 Z, Y,X 7 X,Y, Z 15 X,Z, Y 23 Y,X, Z 31 Y,Z, X 39 Z,X, Y 47 Z,Y, X 8 X,Y,Z 16 X,Z,Y 24 Y,X,Z 32 Y,Z,X 40 Z,X,Y 48 Z,Y,X
This program was originally written in VB3, for running in Windows 3.1 or later.
This month of december 2020 Bob has upgradet it, to work on Windows 10  even on 64 bit machines.
PS: The program is freeware.
