TSudokuA TypeScript-first Sudoku engine

Human techniques, machine precision.

Human-Readable Techniques

Detects named solving techniques like Naked Singles, X-Wings, and Swordfish -- not just backtracking.

SE-Compatible Ratings

Difficulty ratings that match SudokuExplainer, the community standard for 20 years -- 1858/1858 on the benchmark corpus.

Runs Everywhere

Designed for Node.js, browsers, and React Native (Hermes). Zero JVM dependency.

PROJECT STATUS

Phases 1 and 2 (SE 1.0–4.4) are complete with 100% SudokuExplainer parity. Not yet published to npm -- build from source. See the roadmap for what's next.
