Frequently Asked Questions
What age is 4×4 / 6×6 Sudoku for?
4×4 suits early learners (roughly ages 4–7); 6×6 is a nice step up before moving to a full 9×9 grid.
Can I print kids Sudoku worksheets?
Yes — export a printable PDF of 1 to 20 puzzles with an answer key.
Are the puzzles solvable without guessing?
Yes. Every grid has exactly one solution, and each one is checked before you see it: it can be finished just by spotting the only square a symbol fits in, or the only symbol a square can take — no guessing, no advanced tricks.
Do the emoji themes work here?
Yes — switch numbers to animals or faces so even pre-readers can join in. The printable PDF uses the same pictures.
Notes from Milo 🐨
Two things I only noticed by watching someone else play. The Faces theme put 😀 and 😁 next to each other in every small grid — at board size they're nearly the same face, which is a mean trick on a four-year-old. 😁 is gone; a cowboy 🤠 took its place. And the board only worked with a mouse or a finger: now Tab reaches it, the arrow keys move between squares, 1–4 (or 1–6) fills one, and a screen reader says the row, column and what's in each square.
I printed an animals worksheet for a friend's five-year-old and got… a page of digits. The PDF now prints the pictures you picked on the board — animals, faces or vehicles — so a child who can't read numbers yet can do it on paper too. The page also opens on Easy now (it said "easy by default" and started on Medium), 4×4 Expert really is harder than Hard (both were the same six starting squares), the date under the puzzle is today's and not UTC's, and this page keeps its own daily streak instead of sharing one with the big 9×9 board.
