Freecell Solver

This is Freecell Solver - a program that automatically solves layouts of Freecell and similar variants of Card Solitaire such as Eight Off, Forecell, and Seahaven Towers, as well as Simple Simon boards. Freecell Solver is free and open source software freely available under the MIT/X11 License. It can be used online (which requires a modern enough web browser with JavaScript support), or downloaded either as Microsoft Windows 32-bit binaries, or as the C source distribution.

Included with the archive are programs that can automatically provide the starting layouts of several popular Solitaire Implementations.

Freecell Solver can also be built as a library for use within your own Solitaire implementations. A more detailed list of features can be found in the Features List.

21-Feb-2014: Freecell Solver 3.24.0 Release: Mourning Adrian Ettlinger

Freecell Solver version 3.24.0, has been released. Freecell Solver 3.24.0 is available in the form of a source archive, from the download page. Freecell Solver is an open source framework (library and some command line applications), for automatically solving several variants of card Solitaire / Patience games, including Freecell.

This release is dedicated to the memory of Adrian Ettlinger who passed away on 23 October 2013, who was a good Internet friend of the primary maintainer of Freecell Solver (= Shlomi Fish), and who contributed a great deal to Freecell Solver and to Freecell research and programming in general (among other major life achievements, and contributions to man kind). You can read an obituary of Mr. Ettlinger by Shlomi Fish as it was posted to the Freecell Solver Discussions mailing list, and also read an an interview that Fish conducted with him back in 2003.

The new video-editing preset was named in honor of Ettlinger’s previous work in pioneering non-linear video editing back when he worked as an Electrical Engineer (and later as a software developer) for CBS corporation.


In any case, the main highlights of this release are:

  1. New Feature: the -l video-editing (or -l ve for short) flare-based preset that tends to yield shorter solutions on average. See a post with some performance analysis.

  2. A bug was fixed when providing input without a trailing newline character (“\n”). This was reported against the online JavaScript version was Olaf and was fixed globally. Thanks, Olaf!

  3. The distribution now contains the sources for the Split FCC (= Fully Connected Component) Solver which was an unssuccessful attempt to solve Windows Freecell deal No. 384,243 with two freecells. It may prove of general utility in the future, though.

Hope you enjoy this release and we extend our sadness to the other family members and friends of the late Mr. Ettlinger.

07-Oct-2013: Freecell Solver 3.22.0 was Released: Bug Fixes

Freecell Solver version 3.22.0, has been released. Freecell Solver 3.22.0 is available in the form of a source archive, from the download page. Freecell Solver is an open source framework (library and some command line applications), for automatically solving several variants of card Solitaire / Patience games, including Freecell.

The highlights of this version are some bug fixes: the Win32 NSIS (= Nullsoft Installer) package should now build, run and process the presets (e.g: -l as properly). Furthermore, there's a bug fix to the command line flags processing, where flags whose prefixes are known flags were erroneously recognised as such (e.g: --resetjunk vs. --reset).

On the new features side, the JavaScript-based solver now accepts arbitrary fc-solve command line options, so it can be used to solve any of the supported variants of Solitaire, as well as support most other fc-solve features.

Enjoy!

Freecell Solver is an open source framework (library and some command line applications), for automatically solving several variants of card Solitaire / Patience games, including Freecell.

The highlights of this version are some major optimisations to the solving code of Simple Simon, as well as many code cleanups, refactorings and smaller optimisations. Furthermore, the “qualified-seed-improved” preset was added, which yields shorter solutions.

Enjoy!

01-Apr-2013: Freecell Solver Enterprises™ Acquires Google Inc.

1 April, 2013, Tel Aviv, Israel: Due to the spectacular commercial success of Freecell Solver Enterprises™’s Enterprise Edition and its Webscale™ edition, we have amassed quite a bit of cash in the bank, so we decided to make a small but important strategical acquisition. As a result, Freecell Solver Enterprises™ is proud to announce its upcoming acquisition of Google Inc., which will result in an exciting synergical merger.

Some of the upcoming changes would be replacing Google’s tech support (which is notoriously bad) by Freecell Solver Enterprises™’s world-famous and superb tech support (as detailed in the essay “Seven steps to remarkable customer service” by Joel on Software), as well as integrating Google search into Freecell Solver™ for an enhanced experience in solving Freecell. We are also planning on creating a separate YouTube top-level category for card Solitaire-related videos (including screencasts and presentations).

We are sure that the upcoming acquisition is going to allow Freecell Solver Enterprises™ to further its competitive edge, and allow us to have even more significant growth, which will in turn allow us to make even more significant acquisitions. As our CTO, Shlomi Fish, notes: “good times are coming.”.

Soon, people will say “Let’s Freecell Solver Enterprises™ Superheroic Web Search™ it!” instead of “Let’s Google it!”, for an exciting Web 3.141592™ experience.

10-Dec-2012: Freecell Solver 3.16.0 was Released + New Screencast

Freecell Solver version 3.16.0, has been released. Freecell Solver 3.16.0 is available in the form of a source archive, from the download page. Freecell Solver is an open source framework (library and some command line applications), for automatically solving several variants of card Solitaire / Patience games, including Freecell.

This new release took about a month to prepare, and also contains less profound changes than the previous release, but still quite a lot to look for. It features the -l micro-finance-improved and -l qualified-seed presets, which improve upon the average solution length (at the expense of speed). The --flares-choice flag was added and one can specify --flares-choice fcpro to choose based on the lenght of the Freecell Pro moves. Another additional flag is --flares-iters-factor which multiplies the time the flares run at by a factor for a speed/solution-length trade-off.

Finally, the inidividual flares are now recycled and their memory is reused when they are no longer needed which yields a RAM optimisation in certain cases.

More information about all these can be found in the distributed documents of Freecell Solver.

In addition to all that, a new screencast of PySolFC solving Freecell using Freecell Solver is now available on YouTube. Make sure you expand the details for all the credits of the software and other material that was used for its creation.

Enjoy and happy holidays.
