Description

This Sudoku game is essentially a fully browser-based Sudoku application. It not only automatically generates puzzles of different difficulty levels while ensuring each puzzle has a unique solution, but also provides a complete interactive solving experience. This includes real-time input validation, conflict highlighting, pencil mark (candidate number) notation, a timer, as well as undo and redo operations, allowing users to perform logical reasoning just like on real paper.

At the same time, the system also supports a hint feature to help players who get stuck continue progressing, and it can automatically save the current progress to prevent data loss when the page is refreshed. Overall, it combines a Sudoku generator, solver, and game engine, making it suitable not only for entertainment but also for training and challenge purposes.
