SudokuMax - Online Sudoku Game

Play free Sudoku puzzles in your browser. Easy to expert difficulty, hints, offline play, no sign up and no ads.

Play Sudoku from your Chrome toolbar, with no account and no ads. Puzzles are generated on your device, so you can play offline and return to your saved game when you reopen the popup. Choose Easy, Medium, Hard or Expert puzzles. The chooser also includes Master and Extreme to match the Sudokumax website; both currently use Expert puzzles, as explained inside the extension. • Click, type or drag a number into an empty cell. • See the selected cell, its row, column and box, and matching numbers clearly highlighted. • Add pencil notes, erase entries and undo recent moves. • Use up to three hints per puzzle, with a nudge, explanation and optional number reveal. • Play Relaxed with unlimited mistakes, or Challenge with a three-mistake limit. • Pause the timer and hide the board when you take a break. • Switch between light and dark themes. • Keep your current puzzle and preferences on this device. The extension requests no browser permissions and includes no analytics or advertising. Game data stays in the extension’s local browser storage. Optional links open sudokumax.com, which has separate website privacy practices.
