FAQ
How do I teach sudoku with the 4×4 grids?
Start with the rule in kid terms: every row, every column and every box needs 1, 2, 3 and 4 with no repeats. The 4×4 grid keeps the logic visible at a glance, which makes it the standard first step before 6×6.
Can I play these sudoku puzzles online instead of printing?
Yes. Hit Play online above the preview and the page becomes a working sudoku board: tap a cell, use the keypad, and press Check to verify your digits against the unique solution.
How long should one puzzle take?
A focused child solves a 4 by 4 in two to five minutes once the rule clicks. If it takes much longer, solve one together first and let them finish the page solo.
Where can I play sudoku online for free without ads in the board or an account?
Right on this page. Press Play online, tap a cell and type with the keypad; the Check button verifies your digits against the unique solution. There is no sign-up and the board itself carries no ads, so it is safe to hand to a child.
Are the solutions included?
Yes, the final page of the PDF shows every grid solved, with the added digits in green so you can check a student's work cell by cell. Toggle the answer key off if you prefer puzzles only.
