Updated November 2026 · 7 free printables
6x6 sudoku is the step between the small 4x4 puzzles and full 9x9 sudoku. The grid has 36 squares in six boxes of 2 rows by 3 columns, and each row, column and box holds the numbers 1 to 6 once.
About these printables
Here you will find easy pages (20 or more numbers given, four puzzles per page), medium pages with only 14 to 16 clues, a Christmas number page on red and green boxes, and two big one-per-page 6x6 picture sudoku for younger solvers.
Easy 6x6 suits most children from 6 to 8. The medium pages need the second sudoku move, finding the only square in a row, column or box where a number can still go, and are a good challenge for ages 7 to 9.

Frequently asked questions
Is 6x6 sudoku hard?
Not when enough numbers are given. The easy pages can be solved by checking, square by square, which number is missing. The medium pages need a little more searching but never guessing.

They are rectangles of 2 rows by 3 columns, so the grid has six boxes. On our pages every other box is lightly shaded to make them easy to see.
How many 6x6 puzzles are on a page?
Four on the number pages, and one large puzzle with inch-wide squares on the picture pages.
