Master Sudoku: The Ultimate Solver to Finish Any Grid
Overview
- A powerful Sudoku-solving tool designed to handle puzzles of all difficulty levels (easy → expert).
- Provides both full solutions and step-by-step hints so users can learn techniques while finishing a grid.
Key features
- Instant solve: Enter a grid to get a correct completed solution quickly.
- Step-by-step hints: Shows logical solving techniques used (e.g., singles, hidden singles, pairs, X-Wing, Swordfish).
- Difficulty analysis: Rates puzzle difficulty and highlights the hardest steps.
- Interactive solver: Let users apply hints one at a time or auto-complete the puzzle.
- Error detection: Validates input and flags contradictions or illegal placements.
- Multiple input methods: Manual entry, photo upload (OCR), or paste string formats.
- Save & resume: Store in-progress puzzles and review previous solves.
- Accessibility: High-contrast themes and keyboard navigation.
How it works (brief)
- Uses a mix of constraint-propagation and search: eliminate candidates, apply pattern-based rules, then backtrack search when needed for hardest puzzles.
- For explainable hints, it logs the rule applied at each step and the affected cells.
Typical user flows
- Paste or enter a puzzle → get instant solution or start guided mode.
- Upload photo → OCR detects digits → confirm/input fixes → solve.
- Use hint mode to learn techniques while solving manually.
Benefits
- Learn solving techniques through clear explanations.
- Finish any grid reliably—even puzzles requiring advanced pattern searches.
- Save time compared with manual solving; useful for practice and competitions.
Limitations
- Extremely rare puzzles crafted to force huge search trees may need longer solve time.
- OCR may misread poor-quality photos; manual correction may be required.
Target users
- Beginners learning techniques, intermediate solvers practicing advanced rules, and power users who want fast, explainable solutions.
