There are other ways I havent thought of yet...

Fields that were not filled will be populated if the arc is solved. This is done to provide information for solving the next leg, enabling one to solve "chains" of successive turns.

This is a project in active development. Various tests are listed here. Additional resources will be provided as I can create them.
