Updated November 2026 · 6 free printables
Never played sudoku? Start here. The How to Play sheet explains the three rules on small solved grids, walks through finding one missing number, and ends with two practice puzzles.
About these printables
The 4x4 warm-up ladder then gives nine puzzles that add one empty square at a time, from 2 to 10.
After that, the easy 6x6 pages and the large print easy 9x9 sudoku keep many numbers in place, so every empty square can be solved with the first, simplest move: look at the row, the column and the box, and write the one number that is not there yet. Good for kids from 5 and for adults trying sudoku for the first time.

Frequently asked questions
What is the easiest way to learn sudoku?
Begin with a small grid. A 4x4 sudoku uses only four numbers, so the rule is easy to see. Solve a few with someone, saying the reasoning out loud, then move to 6x6 and 9x9.
What is the first trick every sudoku beginner should know?
Pick one empty square and list the numbers already in its row, column and box. If only one number is left, that is the answer. On easy puzzles this trick alone solves the whole grid.
Should beginners use a pencil?
Yes. A pencil and eraser take the fear out of mistakes. On 9x9 puzzles, small pencil notes in the corner of a square help keep track of the numbers that could still fit.
