About this game

Sudoku Master is a clean, focused implementation of the classic number puzzle, built for players who want a no-frills sudoku experience that just works. You select from four difficulty tiers and get an endless supply of fresh puzzles, each generated to have a unique solution. The interface is minimal — tap a cell, tap a number, mark candidates if you want to think a few steps ahead. Mistake highlighting and an undo button are there to help, but you can also turn them off for a purer challenge. Hard and expert puzzles require advanced techniques like X-wings and naked pairs, so there's real depth here for veteran sudoku players. This free online game runs in your browser instantly. Pick a difficulty and start solving.
