Screen time that grows young minds.
Zumo turns play into progress. Kids solve puzzles they love while five thinking skills quietly get stronger — and parents see exactly how, on a dashboard built for grown-ups.
No ads. No email or password for kids — just a code a grown-up creates.
What is Zumo?
Zumo is a small, friendly world of brain-training games for children aged 4 to 12. Every game is designed around a real cognitive skill, and every round a child plays is turned into progress a parent can follow — so time on the tablet becomes time well spent.
Games with a purpose
Sudoku, Memory Pairs, Word Play and more — each one built to stretch a specific way of thinking, not just to pass the time.
Progress you can see
Stars, streaks and skill scores add up behind the scenes into clear reports for parents on how a child is growing over time.
Just-right difficulty
Puzzles scale to a child's age band, so a four-year-old and a ten-year-old each get a challenge that fits — never too easy, never frustrating.
Live Competitions
Scheduled contests where kids race the same puzzle at the same time and climb a live leaderboard. Register ahead, jump in when it starts, and play move-by-move — every score is worked out fairly on the server, in real time, so the winner truly earned it.
Register & join
Sign up for an upcoming contest, then jump straight in the moment it goes live.
One shared puzzle
Everyone solves the exact same board, so the live leaderboard is a fair race to the top.
Win medals
Finish in the top three to collect gold, silver and bronze medals on your profile.
Five skills, growing with every game
Games don't just entertain — each one trains one or more core thinking skills, and the parent dashboard charts how each is coming along.
How it works
From sign-up to first puzzle in a couple of minutes.
A grown-up sets things up
Create a free parent account, add each child, and Zumo hands you a unique login code for them — no email or password for kids to remember.
Your child plays
They open the Kids Zone, type their code, and dive into games matched to their age. Each go earns stars and keeps their daily streak alive.
You watch them grow
Every session flows into your dashboard as activity and skill scores, so you can see strengths, spot gaps, and celebrate progress together.

Grows with your child
Three age bands, each with difficulty tuned to fit — a Sudoku grid, for instance, scales from a gentle 4×4 up to a full 9×9.
Early years — big, playful puzzles that build first logic and memory.
Middle years — richer challenges across all five thinking skills.
Older kids — full-size puzzles that reward focus and strategy.
Why families choose Zumo
Learning that feels like play, wrapped in the safety and control parents want.
Safe by design
Kids sign in with a code, not personal details. No ads, no chat with strangers, no data a child has to hand over.
Real skill building
Every game targets logic, memory, language, spatial reasoning or speed — play with a purpose behind it.
Clear parent insight
See what your child played, how they did, and which skills are climbing — no guesswork.
Screen time you control
Give each child a credit allowance so play stays balanced, and top up when you choose.
Motivation that sticks
Stars, streaks, live competitions and medals turn practice into something kids come back to on their own.
Built for the whole family
One account covers every child, with room for more than one grown-up to help manage it.
Questions parents ask
The short answers. Anything else, email contact@zumo.vn.
What ages is Zumo for?
Zumo is built for children aged 4 to 12. Games are grouped into three age bands — 4–6, 7–9 and 10–12 — and difficulty is tuned to each one, so a Sudoku grid scales from a gentle 4×4 for the youngest up to a full 9×9 for older children.
How does my child sign in?
With a short code, not an account. A grown-up creates a parent account, adds each child, and Zumo issues that child a unique login code. Children never enter an email address, a password, or any other personal detail.
Does Zumo cost anything?
Creating a parent account is free, and every new family starts with a balance of credits. Games cost a few credits per round, and you set how much of the family balance each child may spend, so screen time stays capped without you having to police it.
Is Zumo safe for children?
Yes. There is no advertising anywhere in Zumo, no chat or messaging between users, and nothing a child has to hand over to play — they sign in with a grown-up-issued code. A competition leaderboard shows only the display name a parent chose, an avatar and a score.
What are live competitions?
Scheduled contests where every registered child solves the same puzzle at the same time and climbs a leaderboard that updates as they play. Scores are calculated on the server from each move, so the result is a fair race, and the top three finishers earn gold, silver and bronze medals.
What can I see as a parent?
The parent dashboard shows each child's recent sessions, the stars and streaks they have earned, and how their five skill scores — logic, memory, language, spatial reasoning and processing speed — are trending over time. One account covers every child in the family, and you can invite another grown-up to help manage it.
Which skills do the games train?
Five: logic, memory, language, spatial reasoning and processing speed. Every game is mapped to one or more of them — Sudoku to logic, Memory Pairs to memory, Word Play to language — so playing feeds directly into the skill chart a parent sees.
