- logical hints
- instead of revealing a random number, they should provide tips how to move forward
- the tips should start vague, like:
look for pointing pairs - if you still don't get it, it should be more specific like:
look in rows - then it could tell you the specific row
- in the end could show you the specific pointing pair
The goal of this program is to have a collection of sudoku tools.
Planned is a solver, a tool to rate the difficulty of sudokus, a universal sudoku game, and a game mode that gives you useful hints when you get stuck. Or even lets you train to find specific reduction techniques.
Sudokuwiki has a great list of techniques on how to solve sudokus. These can be used to grade puzzles.
