# Solver

PySolFC contains integration with a number of solitaire game solvers:

- fc-solve
- Black Hole Solver

The solvers may need to be installed separately to use them, depending on your PySol configuration.

To use the solver, first run a game that's compatible with the solver, and then set the configuration settings.

## Configuration Options

The preset option determines the configuration that the solver uses. The different configurations affect how the solver goes about trying to find a solution. More details on the different preset options can be found on the fc-solve website.

The max iterations setting controls how many game states the solver can review for that given game. A higher number means the solver is more accurate, but takes longer to run.

Once you've set the configuration options, you can start the solver, and then demo the found solution.
