Sudoku for Kids (4×4)
6A 4×4 grid with 2×2 boxes and only the digits 1 to 4. Small enough for a child to finish in a few minutes.
Sudoku for Kids (6×6)
6A 6×6 grid using digits 1 to 6. The natural next step once 4×4 feels easy.
Very Easy Sudoku
10Most cells are already filled. Good for a first 9×9 puzzle, or for solving on a train without much concentration.
Easy Sudoku
12More numbers filled in from the start, so there are fewer blanks to work out. The right place to learn the pattern.
Medium Sudoku
12Fewer givens than easy. You will need to scan properly rather than spot answers at a glance.
Hard Sudoku
12Minimal givens. Expect to work through several passes and lean on pencil marks.
Expert Sudoku
10Very few givens. Basic scanning will stall; you will need pencil marks and elimination.
Evil Sudoku
8The fewest givens we generate. Long, stubborn, and not recommended as a warm-up.
Try Killer Sudoku
Same 1–9 rules, but the grid starts empty and every dashed cage must add up to its target sum, with no digit repeated inside a cage. A fresh challenge once classic sudoku feels routine.
Play killer sudoku →How to play sudoku
The grid is 9 squares across and 9 down, divided into nine 3×3 boxes. Fill every empty cell with a digit from 1 to 9 so that:
- each row contains 1–9 with no repeats,
- each column contains 1–9 with no repeats,
- each 3×3 box contains 1–9 with no repeats.
The numbers printed at the start cannot be changed. Every puzzle here has exactly one solution, so you never need to guess, the answer can always be worked out by logic alone.
Three tips that actually help
Start where the grid is fullest. Find the row, column, or box with the fewest blanks. With only one or two cells left, the missing digits are often forced.
Work one digit at a time. Pick a number that already appears several times. Scan the rows and columns it sits in, those lines are now closed to it, which often leaves only one legal cell in a box.
Pencil in the maybes. When a cell has two or three candidates, note them small in the corner. As other cells fill in, the candidates get eliminated and the answer falls out on its own.
Frequently asked questions
What are the rules of sudoku?
Fill the 9x9 grid so that every row, every column, and every 3x3 box contains the digits 1 to 9 exactly once. No digit may repeat in any row, column, or box. Every puzzle has one correct solution.
How do I start a sudoku puzzle?
Look for the row, column, or 3x3 box that already has the most numbers in it. The fewer blanks there are, the easier it is to work out what must go in them.
Is sudoku hard to learn?
The rules take about a minute to learn. Start on easy, where most cells are already filled, and the logic becomes clear fairly quickly.
Do I need to sign up to play?
No. Every puzzle is free to play online or print, with no account, no watermark, and nothing to install.
