Sudoku without the clutter
PuzzleGrids is a clean, fast place to play Sudoku in your browser. There are five kinds of puzzle: easy, medium, hard and expert on the classic 9x9 grid, plus a quick 6x6 mini Sudoku. You can play as many as you like, and each one is generated fresh when you open it.
The game includes pencil notes, undo, hints, a timer, mistake highlighting and a dark theme. Progress is saved on your device, so you can close the tab mid-puzzle and carry on later.
How Sudoku works
Fill the grid so that every row, every column and every 3x3 box contains the digits 1 to 9 exactly once. That is the whole rule set. No arithmetic is involved; it is a logic puzzle. New to it? Read how to play Sudoku, then start with an easy puzzle.
Questions
Is PuzzleGrids free?
Yes. Every puzzle and every difficulty level is free, with no account, no download and no limit on how many you play. The site is paid for by adverts.
Does every puzzle have only one solution?
Yes. Each puzzle is checked by a solver before you see it, and it is only used if it has exactly one solution. You never need to guess between two valid answers.
When does the daily Sudoku change?
A new daily puzzle appears at midnight UTC. Everyone gets the same puzzle on the same day.
Is my progress saved?
Yes. Your current game for each level, your daily result and your streak are saved in your browser on this device. Nothing is sent to a server, so progress does not follow you to another device.
Can I play on my phone?
Yes. The grid and number pad are sized for touch screens, and the site also works with a keyboard on desktop.
