A fast web-based solver for Sudoku puzzles and variants. It prioritizes raw speed over human-style solving techniques to allow exploration of complex solution spaces.
It is hosted at http://sigh.github.io/Interactive-Sudoku-Solver
- Sudoku Variants: Supports a large number of constraints natively, and the ability to define custom constraints.
- Non-Standard Grids: Supports any grid size up to 16x16, including non-square grids.
- Explore Solution Spaces: Verifies uniqueness and provides solution counts, including estimates for large solution counts.
- Scripting: Provides a JavaScript Sandbox for programmatic puzzle generation and solving.
See the help page for more extensive documentation.
Run locally using Jekyll, e.g.
jekyll serve --port=8080npm testFor the main app and solver docs, see js/README.md, js/solver/README.md, js/solver/SOLVER_ENGINE.md.
The main application and solver has historically been hand-coded. More recently it uses AI-assistance with close review.
The development tooling and technical documentation are mostly AI-generated, with oversight mainly to ensure correctness.
The tests are almost entirely AI-generated with little oversight. The exception is the e2e test suite which is manually-curated.
Contributions are welcome including:
- New constraints/variants
- Solver optimizations
- UI improvements
- Bug fixes
- Code health and documentation
