From the README

Pure‑frontend infinite‑generation Sudoku puzzle web app. Zero backend, single‑file, deployable on GitHub Pages.

A fully‑featured browser‑based Sudoku game built with vanilla HTML / CSS / JavaScript. Designed for open‑source release and supports GitHub Pages static deployment.

Instead of static pre‑stored puzzle banks, this project implements a native Sudoku generation algorithm: generate a valid full solution board, then perform hole‑digging with uniqueness verification to guarantee every puzzle has exactly one valid solution.
