Printable sudoku

Fill the grid so that every row, every column and every 3 × 3 box holds the digits 1 to 9 once each. Each of these grids has a single solution and can be reasoned all the way to it — no guessing, however tricky the level.

Every day there is a new grid at each of three levels, dealt to everybody alike. Pick a level, print the sheet, and take it wherever a screen would not go.

How to play

Fill the grid so every row, every column and every 3 × 3 box holds the digits 1–9, each exactly once.

A few digits are given; the rest is deduction from what already stands.

There is exactly one solution, and it never needs a guess.

A finished grid: the shaded row, column and box each hold 1–9 exactly once — and so does every other one.

Questions people ask

Is it free?
Yes. The sheets, the boards on the site and the archive are free, without an account and without advertising. The PDFs are made once a day and anyone may download them.
How many puzzles are there a day?
One new board a day at each level — Gentle, Steady, and Tricky — the same for everybody, dealt at midnight UTC. Earlier days stay downloadable in the archive below.
Do I need to sign up?
No. Every sheet downloads without an account. An account only keeps your online plays and your streak in one place across your devices.
Does every puzzle have exactly one solution?
Yes. Every board is checked to have a single solution and to be solvable by reasoning alone — no guessing is ever needed. The solution is not printed; the sheet holds the puzzle and the rules.
May I hand the sheets out or use them in a classroom?
Yes — print, photocopy and hand them out as you like, for a class, a club or a waiting room. Only leave the credit line at the foot of the sheet where it is.
