Don Woods' Freecell Solver

Current Source Code for Freecell Pro

This is the source code for the famous Freecell solver by Don Woods. It is basically 4 different solvers for four different Freecell variants which are using a very similar algorithm. Maybe it is possible to abstract the game rules and integrate all of them into one solver.

Note that a more optimized derivative of this solver (for Freecell alone), which was modified by Wilson Callan and Adrian Ettlinger, is available as part of Freecell Pro. FC-Pro is an open-source GPLed program, whose source code is available.
