What works at age 4
At 4, the smallest sudoku is the right one: 4×4 squares, four pictures, difficulty “Easy”. Here 8 to 10 of the 16 squares are already filled in, and often only one or two pictures are missing per row. Your child doesn’t need numbers, reading or writing – recognizing animals, fruit or colors is enough.
They don’t need the full rule with rows, columns and boxes right away either. One part of it is plenty to start with: “Each animal only once in every row.” Columns and boxes come along later on their own.
Place, don’t draw: the cut-out sheet
Four-year-olds rarely manage to draw a picture neatly inside a square. That’s why there is a 4×4 sheet “with cut-outs”: each puzzle comes with a page of exactly the missing pictures. Cut them out (or prepare them yourself) and let your child place them on the grid. If a picture doesn’t fit, it simply gets moved – the glue only comes out once everything is right.
No scissors needed for the color sudoku: your child colors each empty square with the matching crayon.
Tips for parents
- Name things first: before the first puzzle, name all the pictures in the key together – “dog, cat, bunny, frog”.
- Show one row: run your finger along a row with three pictures: “Who’s missing here?”
- Keep it short: finishing one puzzle is better than starting three. Stop while it’s still fun.
- Don’t push: if it doesn’t click yet, simply try again a few weeks later.
Once 4×4 on “Easy” works reliably, continue with sudoku for 5-year-olds. Everything about the smallest grid is on the 4×4 sudoku page.

Frequently asked questions
Isn’t sudoku too early at age 4?
Not if the puzzle is small and uses pictures instead of numbers. A 4×4 on “Easy” can be solved with a little help. If it doesn’t work yet, that’s fine – just try again later.
Online or on paper?
Both work. Online, a wrong square wiggles briefly; on paper, kids also practice cutting, gluing and coloring.
Which worksheet should I print first?
“4×4 · Easy · Animals” – or the cut-out version if your child doesn’t want to draw yet.
