Learn/Practice Sudoku

A browser-based Sudoku app designed to help players learn and master solving strategies. The game offers five difficulty levels—Easy through Hardest—each requiring different techniques to solve. Players can access strategy tutorials, request step-by-step hints, and use a notes feature to track candidates.

The app functions as a progressive web app playable on phones and desktops. It tracks progress and saves interrupted games in local storage, counts mistakes without penalizing players, and lets users auto-fill notes if desired. The maker describes building it with AI coding assistance to solve the problem of learning Sudoku strategies effectively.
