Classic number puzzles

Sudoku.com - Classic Sudoku is a mobile version of the familiar 9×9 number puzzle. Fill each empty cell so that every row, column and 3×3 box contains the numbers 1 through 9 without repeats. It suits both people learning the rules and regular players looking for a puzzle at a chosen level of challenge.

Choose how challenging to play

The game offers six difficulty levels, from easy puzzles to expert challenges. You can take a straightforward grid for a brief break or work through a tougher one that calls for more careful deduction. Daily challenges and seasonal events add goals beyond completing a standard puzzle.

Tools for solving

Notes let you record possible numbers in a cell, much like jotting them down on paper, and update as you fill in the grid. Duplicate highlighting helps spot repeated numbers in a row, column or box. Hints can help when you are stuck, while auto-check can show mistakes as you play. If you make an unwanted move, undo and erase tools let you correct it.

Progress statistics track results for each difficulty, including best times. Games are saved when you leave, so you can return to an unfinished puzzle later. These options make the app useful for casual solving as well as for players who want to follow their performance over time.
