Free Daily Sudoku
A new puzzle every day — no download, no account, no ads.
How to play
Fill the 9×9 grid so that every row, every column, and every 3×3 box contains the digits 1 through 9 exactly once. Select a cell, then click a number below the board (or use your keyboard) to fill it in. Wrong guesses count against your mistake tally but won’t lock the cell — you can always correct them. Pick a harder (or easier) puzzle any time with the switcher above the board — your progress on each difficulty is saved automatically in this browser, so you can close the tab and pick up right where you left off.
Coming to iOS and Android
This is the exact same daily puzzle that will be featured in the Grandmaster Sudoku apps, currently in development for iOS and Android — once they’re live, solving today’s puzzle here and again on your phone will show the identical grid both times.
Want to play with friends?
Sudoku Multiplayer has three ways to play together: race on matching puzzles, solve one grid together in co-op, or split into teams and battle for the win.
