Sudoku for Kids Online: 4x4 and 6x6 Picture Sudoku

Choose a 4x4 or 6x6 grid, a level, and pictures or numbers. Tap an empty square, then tap a picture to put it there. Every picture must appear once in each row, each column and each box. Wrong tries get a gentle hint, Check shows what needs another look, and Print makes a puzzle page, cut-out pictures and an answer page.

Free to use, no sign-up. Everything runs in your browser: nothing you type is uploaded.

How to use it

  1. Choose the grid and the pictures

    Pick a 4x4 grid for beginners or 6x6 for the next step, then a level. Choose pictures from fruit, animals or shapes, or switch to numbers. Each puzzle has a puzzle number, so you can come back to the same one.

  2. Tap a square, then tap a picture

    Tap an empty square on the board. It lights up, together with its row, column and box. Then tap one of the pictures underneath to put it there. The eraser clears a square. On a keyboard use the arrow keys and the number keys.

  3. Use the hints and Check

    If a picture does not fit, the square gives a little wiggle and a kind hint. Press Check at any time to see which squares need another look. When the last square is right, a small party starts.

  4. Print it for the table

    Press Print for the puzzle page with cut-out pictures, so younger children can place real pieces, and a second page with the answers. Press New puzzle for a different one every time.

Ideas for class and home

  • A first logic puzzle for ages 5 to 7

    A 4x4 picture sudoku on easy level is a calm way to teach 'only once in each row and column'. Work on the class screen together, with children coming up to choose the next picture.

  • Quiet time and rainy days

    Print a stack of puzzles with different puzzle numbers and keep them in a folder for early finishers or the car. A logic puzzle book gives the same calm challenge when the free ones run out.

  • Party and holiday activity

    Print the 6x6 picture sudoku and the cut-out pictures for each guest at a birthday party or a family gathering. Everyone gets the same puzzle, and the first to finish picks the next game.

  • Homeschool and brain-break time

    Use numbers instead of pictures to link the puzzle to maths, or pictures of animals during a nature unit. Move up from easy to hard as your child gains confidence, and keep a note of the puzzle numbers solved.

Questions and answers

Is the sudoku for kids free?

Yes. The puzzles are free to play and to print, with no account or sign-up, and there is no limit on how many puzzles you can make.

Does every puzzle have only one solution?

Yes. Each puzzle is built so that exactly one answer is possible, which means children can always solve it by thinking, without guessing. The answer page prints with it.

What is the difference between 4x4 and 6x6?

The 4x4 grid uses four pictures and 2x2 boxes, which suits ages 5 to 7. The 6x6 grid uses six pictures and boxes of 2 by 3 squares, a good next step for ages 7 to 10.

Where is my game stored?

The game lives only in this page on your device. Nothing is sent to a server, and closing the page clears it. Use the puzzle number to get the same puzzle again.
