Fewer clues, more thinking
By 5, many children have already solved their first picture sudokus. Now it can get trickier – but still in the small 4×4 grid. On “Medium”, only 6 or 7 pictures are given; on “Hard”, just 4 or 5. Looking only at the rows won’t get you far any more: now columns and the 2×2 boxes matter too.
The box trick
The most useful tool at this age is the question “Where can the dog still go?”:
- Pick a 2×2 box that is still missing the dog.
- Check with your finger: is there already a dog in the row or column next to it?
- If only one empty square is left in the box, the dog goes exactly there.
Once kids have discovered this trick, they can solve the hard 4×4 puzzles too.
First numbers – no adding up
Children who are confident with pictures and know the digits 1 to 4 can try the same puzzle with numbers instead of pictures. There is no arithmetic involved: the digits are just symbols, like the dog and the cat before. It’s a gentle bridge to the sudokus kids will meet later at school.
Tips for parents
- Being stuck is allowed: a short struggle is where the learning happens. Help with a question after a while, not with the answer.
- Ask for reasons: “Why does the cat go here?” – that turns guessing into real thinking.
- Level mode: the first 50 levels are 4×4 and slowly get harder – with stars as a reward.

Frequently asked questions
When is my child ready for 6×6?
When they solve 4×4 on “Hard” without help. Until then, it’s worth staying with 4×4.
Does my child need to count for number sudoku?
No. Recognizing the digits 1 to 4 is enough. Sudoku involves no arithmetic.
