This is Freecell Solver version 6.8.x, a program that automatically solves most layouts of Freecell, and similar Solitaire variants as well as those of Simple Simon.
Freecell Solver is distributed under the MIT/Expat License ( http://en.wikipedia.org/wiki/MIT_License ), a free, permissive, open-source license.
Note that the Freecell Solver source and Win32 binary distributions do not provide a graphical user-interface (GUI) and are primarily meant to be used by Solitaire researchers and software developers. If you’re looking for a suitable GUI based on Freecell Solver, see our links at:
I hope you’ll enjoy using Freecell Solver, and make the best of it.

The program is called "fc-solve". You invoke it like this:
fc-solve board_file
board_file is the filename with a valid Freecell startup board. The file is built as follows:
It has the 8 Freecell stacks.
Each stack contains its cards separated by a whitespace and terminated with a newline character( it’s important that the last stack will also be terminated with a newline !). The cards in the line are ordered from the topmost card (= the card right on the virtual table and the one with the most cards placed on it) in the left, to the bottommost card in the right (= the card with no other cards placed on it).
A card string contains the rank of the card followed by its suit.
The card number is one of: A,1,2,3,4,5,6,7,8,9,T,J,Q,K. Alternatively,
10 can be used instead of T, but using that is discouraged and
is only supported for backward compatibility. The card suit is one of: H,S,D,C (standing
for Hearts, Spades, Diamonds and Clubs respectively).
Here is an example board: (PySol/Microsoft board No. 24)
4C 2C 9C 8C QS 4S 2H 5H QH 3C AC 3H 4H QD QC 9S 6H 9H 3S KS 3D 5D 2S JC 5C JH 6D AS 2D KD TH TC TD 8D 7H JS KH TS KC 7C AH 5S 6S AD 8H JD 7S 6C 7D 4D 8S 9D
Visually, it appears as this:
As can be seen, the four of clubs (4C), five of hearts (5H), etc. are at the bottom of the stacks and the start of the lines in the board input.
And another one: (PySol board No. 198246790)
KD JH 5H 7D 9H KC 9D 3H JD 5D 8H QH 7H 2D 4D 3S QC 3C 6S QS KS TC 9S 6D 9C QD 8S TD TS 8C 7S TH 2C AS 8D AC AH 4H JC 4C 6H 7C 4S 5S 5C JS AD KH 6C 2H 3D 2S
Starting from Freecell Solver 3.14.x, a stack can also start with a leading colon (":"). This is to allow input from states as output by Freecell Solver using the -p option.
You can specify the contents of the freecells by prefixing the line with "FC:" or with "Freecells:". For example:
FC: 3H QC
will specify that the cards 3 of hearts and queen of clubs are present in the freecells. To specify an empty freecell use a "-" as its designator.
If there’s another "FC:" line, the previous line will be overridden.
You can specify the contents of the foundations by prefixing the line with "Founds:" or with "Foundations:" and then using a format as follows:
Founds: H-5 C-A S-0 D-K
Hence, the suit ID followed by a dash followed by the card number in the foundation. A suit that is not present will be assumed to be 0. Again, if there’s more than one line like that, then the previous lines will be ignored and overridden.
The program will stop processing the input as soon as it read 8 lines of standard stacks. Therefore, it is recommended that the foundations and freecells lines will come at the beginning of the file.
The program will process the board and try to solve it. If it succeeds it will output the states from the initial board to its final solution to the standard output. If it fails, it will notify it.
For information about the various command-line switches that Freecell
Solver accepts, read the USAGE.txt file in this directory.
To solve Simple Simon boards append --game simple_simon right after
the "fc-solve" program name.
Several programs which can generate the initial boards of various Freecell
implementations can be found in the "board_gen/" sub-directory. Read the
README.txt file there for details on how they can be compiled and used.
In any case, they can save you the time of inputting the board yourself.
A layout in the middle of the MS Freecell deal No. 109 solution:
Foundations: H-6 C-9 D-2 S-0 Freecells: QS 3S 2S KD : 8H 3D : KS QD JC : AS 8D TD 7D JH TS 9D : 7S 6D : 5S : KH QC JD TC 9H 8S 7H 6S 5D 4S : KC QH JS TH 9S : 4D
Similar, but with an empty Freecell:
Foundations: H-6 C-9 D-2 S-0 Freecells: QS 3S - KD : 8H 3D 2S : KS QD JC : AS 8D TD 7D JH TS 9D : 7S 6D : 5S : KH QC JD TC 9H 8S 7H 6S 5D 4S : KC QH JS TH 9S : 4D
Likewise, only without leading colons where unnecessary:
Foundations: H-6 C-9 D-2 S-0 Freecells: QS 3S - KD 8H 3D 2S KS QD JC AS 8D TD 7D JH TS 9D 7S 6D 5S KH QC JD TC 9H 8S 7H 6S 5D 4S KC QH JS TH 9S 4D
The file USAGE.txt covers all of Freecell Solver’s command line options,
but it may be too exhaustive for casual users. As a result, here is a shorter
tutorial. First of all whenever invoking fc-solve one should add the
flags -p -t -sam -sel which will make the solution easier to understand. Then,
assuming the board could be successfully solved, one will be given the layouts
in the solution (in the format given above) vis-a-vis with the moves as the
string. Note that the indexes of the resources given in the moves are
0-based rather than the more natural 1-based notation.
