Add Hint Feature #5
Description
Description
Add a feature where the user can request a hint to help solve the puzzle. Hints may reveal a correct value or highlight a cell or region where progress can be made.
Why
Hints help beginners learn and keep users engaged without making the game too difficult.
Goals
- Add a "Get Hint" button to the UI.
- On click, highlight a cell and optionally show a value.
- Respect fixed/filled cells and avoid revealing multiple values at once.
Suggested Implementation
- Use the solver to find the next correct value.
- Choose a random solvable cell and suggest it.
