SudokuScope

What it is

SudokuScope is a multi-module Gradle workspace built to explore, analyze, and publish Sudoku boards. It combines a fast, framework-free solver core with a desktop client and a web API so the same engine can power both local and browser-based experiences.

Behind the scenes

• Core module ships a bit-mask backtracking solver with MRV heuristics and solution counting.
• Target-count search generates candidate grids and prunes them toward a desired solution count.
• GameState uses command objects for undo/redo and event observation.
• JavaFX MVVM UI debounces edits and offloads analysis to an async solver service.
• Spring Boot REST API exposes analysis via POST /api/analyze for future web clients.
• Benchmarks and end-to-end tests validate solver correctness and performance.

Why it matters

The project demonstrates production-friendly architecture: clear module boundaries, performance-conscious algorithms, and a testing strategy that spans unit, web, and integration layers. It is designed to scale into a public-facing puzzle platform.
