180 puzzles across nine packs — one for every grid size and difficulty. Each PDF opens with a rules line, prints four 6×6 boards to a page (two for the bigger grids), and finishes with numbered answer sheets. The puzzles were generated for these packs only, so nothing in them spoils the daily puzzle or the library on the site.
Printing These Sheets
- Scale: print at 100% or “actual size”. The pages are US Letter with margins wide enough that A4 paper crops nothing.
- Ink: black and white, grayscale, draft quality — the grids are plain rules and digits, so nothing is lost.
- Answers: the last few pages of each pack. Print only the puzzle pages if you want to keep the key out of reach.
- Kids and classrooms: the 6×6 easy pack has the largest cells and the most givens — the one to hand out first.
Printable Mini Sudoku Questions
Are the printable Mini Sudoku packs really free?
Yes. Every pack is a free PDF — no account, no email, no watermark. Download the ones you want and print as many copies as you like.
Can I use these in a classroom or a puzzle club?
Please do. Teachers, care homes and puzzle groups are welcome to print and hand out copies. The 6×6 easy pack is the usual starting point for kids. The only thing we ask is that you do not resell the packs or strip the site name off the page.
What print settings should I use?
Print at 100% or "actual size" rather than "fit to page", on US Letter or A4 — the pages are Letter-sized with a margin wide enough that A4 crops nothing. Black and white is fine; there is no colour anywhere in the packs.
Where are the answers?
At the back of every pack. Puzzle pages come first, then the answer sheets, numbered to match. Print just the puzzle pages if you would rather not have the key sitting on the table.
Are these the same puzzles as the ones on the site?
No. The 180 puzzles in these packs were generated for print only, so nothing here spoils the daily puzzle or the 900-puzzle library you can play in the browser.
How hard are the difficulty levels?
Easy boards can be finished with naked singles alone. Medium needs hidden singles. Hard means the straightforward scans run out and you will want pencil marks. It is the same grading the puzzles on the site use.
