✅ Complete! No numbers used.
Meera is 6. She's in Reception. She knows her animals, her colours, and roughly which way a bear faces. Numbers? Still learning.
Her teacher, Miss Kapoor, wanted to run a logic activity — but every sudoku resource started with numerals. Too many kids froze before they even tried.
Then she found the Animal Kingdom 4×4 on Kidoku Live.
She put a panda, tiger, fox, and owl on the board. The rule: each row and column has each animal exactly once. No numbers. No counting. Pure pattern logic.
Meera pointed at an empty cell, thought for a moment, and placed an owl.
It was correct.
She solved the grid unaided. When it completed, she looked up and said: "Can I do another one?"
That's when Miss Kapoor realised: the logic was never the barrier. The numbers were.
No reading required. No numbers. Just animals and pattern logic.
Choose panda, tiger, fox, or owl as your avatar. A grown-up types the nickname. Then it's all hers.
Touch an empty cell, see the four animals. Tap the right one. Each row and column needs each animal once. That's the whole rule.
When the last animal is placed correctly, the grid celebrates. Confetti, stars, and a winner card. Then she asks for another.
No digits, no reading, no counting. The Animal 4×4 is playable by children who don't yet recognise the number 4.
It's the same cognitive skill as a full 9×9 — elimination, pattern recognition, spatial reasoning. At a pace that fits a 6-year-old.
After mastering animals, switching to digits feels natural. The logic is identical — only the symbols change. She's ready for numbers before she knows it.
Same Puzzle. Different Representations.

Everything you need to know about Kidoku Live for this use case.
Yes — with the right version. Kidoku Live's Animal Grid 4×4 replaces all numbers with animal pictures. A 6-year-old only needs to recognise that each animal must appear exactly once in each row and column. No reading, no number recognition, and no prior puzzle experience is needed.
Picture sudoku replaces the nine digits of classic sudoku with images — animals, superheroes, space objects, or other themes. The logical rules are identical: each symbol appears exactly once per row, column, and box. Picture sudoku is designed specifically so young children can engage with the logic before number fluency is established.
Yes. Animal Grid sudoku builds spatial reasoning, pattern recognition, and logical deduction — skills that underpin both mathematics and reading comprehension. It is used by early years teachers and occupational therapists as a low-pressure cognitive development activity. No number knowledge is required.
The 4×4 Animal Grid is designed for children aged 5–8. Most 6-year-olds can complete a round independently after one or two practice attempts. The grid is small enough to fit comfortably on a phone screen and the puzzles typically take 3–8 minutes to solve.
Yes. Kidoku Live collects zero personal data, has no chat feature, and generates safe usernames automatically. No account is needed. No external links appear during gameplay. It is designed to be safe for unsupervised use by children as young as 5. The Animal Grid contains no text-based content — the child interacts only with pictures.
Yes, and they can win fairly. An older sibling on a larger grid (6×6 or 9×9) and a 6-year-old on a 4×4 Animal Grid compete in the same session. The time-based leaderboard is fair: a faster 4×4 completion beats a slower 9×9 completion. This means the youngest child in the room can legitimately come first.
Completely. The logical process — scanning rows and columns to eliminate possibilities and place the one remaining symbol — is identical in Animal Grid and Classic 9×9. Children who use picture sudoku develop the same foundational deductive reasoning skills. Many seamlessly transition to numbered sudoku after a few weeks on Animal Grid.
Yes. Kidoku Live is used in classrooms from Reception and Year 1 upward. The Animal Grid is a common choice for early years and KS1 classes because it requires no reading, no number knowledge, and works on any classroom device including tablets and Chromebooks. No login or app installation is needed.
The Animal 4×4 is live right now. She can solve her first sudoku in the next three minutes — and never once see a digit.
