Singapore primary maths, P1 to P6
Maths practice that feels like an adventure
Numi Isles is a free maths game for primary school kids. Short rounds follow the MOE syllabus, friendly companions called the Numi cheer every step, and a grown-up stays in charge.
- Free, nothing to buy
- No ads
- No passwords for kids
How it works
Little quests, every day
A sleepy fog has drained the colour from the Numi Isles. Every quest your kid solves lights a lantern on an island trail, and bit by bit the isles come back to life.
Pick a Numi
Every explorer starts with a companion: Kopi the otter, Kaya the pangolin and Sambal the hornbill. 13 more Numi are waiting to be found along the way.
Play short rounds
A round is 8 questions on one skill and takes a few minutes. Missed questions come back once as a Second Chance, with free hints, a read-aloud button and a worked solution that shows how.
Bring the isles back
Stars, badges and a kind streak celebrate progress, and each island fills with colour as the fog lifts. Progress is never taken away, and Streak Shields and rest days can carry a streak through a busy day.

Fresh questions every round. The game makes its own questions, so practice never runs out. Lower tiers lean on pictures like bar models, number lines and fraction shapes; higher tiers add word problems set in Singapore life. And 50 Speed Dashes, 60 seconds each, build quick recall of times tables, number bonds and more.
Independent. Numi Isles follows the syllabus but is not made, endorsed or checked by the Ministry of Education. It is practice to support learning, not a replacement for school or a teacher's advice.
Safe by design
Made for kids, with grown-ups in charge
Numi Isles is built so a child can play on their own without meeting strangers, seeing ads or giving away more than a nickname.
- High five
- Wow
- Star
- Go go go
Plus friend requests and race challenges. No typing, no photos, no links.
No passwords for kids
Kids never make or type a password. A grown-up lets them in, by approving the code on the kid's screen or by sending a sign-in link or code.
A grown-up for every account
Every kid account is made or approved by a parent or guardian, and up to two grown-ups can look after one kid.
Friends by code, and no chat
Kids add friends only by typing a friend code shared in person. There are no public profiles and no search, and nobody can type messages to a kid except their own grown-ups.
Grown-ups decide
Switch friends and challenges off, or approve each new friend first. Friends see game things like a nickname, Numi, level and badges: never answers, and nothing about the grown-ups.
No ads, nothing to buy
No advertising, no in-app purchases and no tracking scripts. Shells are pretend money, earned by playing and spent on hats and scarves for the Numi.
As little data as we can
We ask for a nickname, not a name, and never a birthday, school or photo. The game's server and database are in Singapore.
The details, including a summary written for kids, are in our Privacy policy.
For grown-ups
A calm dashboard, and the controls you need
Grown-ups have their own account, separate from their kids' accounts. Sign in with Google or with a code sent to your email: no password for you either. One grown-up can look after up to six kids.
See how they are doing
This week's XP, rounds, minutes and first-try accuracy, the last 14 days of play, and a mastery map of every island at their level.
Know where to help
What they are doing great at, what could use practice, and their recent mistakes: the question, their answer and the right one.
Set the pace
Choose the level, a daily goal and up to two rest days a week, and float the islands school is teaching to the top of the map.
Send a cheer
A sticker and a short note, up to 80 characters, straight to their inbox.
Friends on your terms
Approve new friend requests, or switch friends and challenges off altogether.
Devices and accounts
See every device a kid is signed in on and sign any of them out, invite a second grown-up, or delete an account and everything in it.
Your first sign-in creates your grown-up account.
Questions
Good to know
How much does it cost?
Nothing. Numi Isles is free, with no ads and nothing to buy.
Which devices does it work on?
It runs in the web browser of an iPad or other tablet, a phone or a computer: nothing to download. On an iPad or a phone you can add it to the Home Screen, and it then opens full screen like an app. It needs an internet connection to play.
Does my kid need an email address or a password?
No. Kids have a nickname, never an email address, username or password. A grown-up signs them in on each device, and can sign any device out again.
Which levels and topics does it cover?
Primary 1 to Primary 6, following the MOE Primary Mathematics syllabus (2021). Set your kid's level in the grown-up area; all six worlds stay open, so they can also revise an earlier level or peek at the next one.
Is it made by the Ministry of Education?
No. Numi Isles is independent. It follows the syllabus, but it is not made, endorsed or checked by the Ministry of Education.
Can teachers use it with a class?
Numi Isles is made for families: every kid account belongs to a parent or guardian, who sets it up. There are no class or school accounts, but teachers are welcome to tell families about it.
What happens to my kid's data?
We keep only what the game needs, like a nickname, a level and their answers, so the game can pick the right questions and you can see how they are doing. No ads, no selling, no tracking. Our Privacy policy has the details, with a summary written for kids.
How do I delete an account?
In the grown-up area: in a kid's settings for their account, and in Settings for your own. Or write to support@numinumi.appand we will do it for you.
Ready to set sail?
Kids pick a nickname, a level and their first Numi, then a grown-up lets them in. That is all it takes.
