How the math game works
Every run is full of questions. Every answer is a jump into the right lane.
Kids swipe to dodge, jump and slide. When a math gate appears, they answer with their feet. That turns a page of sums into lots of quick, playful answers.
Run into the answer
A gate shows a question and three answers. The right lane earns bonus coins. A wrong one costs a heart and shows the solution right away.
Rescue animals
Right answers free animals from the vines, the first after just 10. Each one helps: the elephant carries your child through crates, the frog jumps higher.
Reviews on Google Play
“The math happens by accident.”
A great app for bringing math to children through play! As a primary school teacher, I find it especially practical that the topics and number ranges can be adjusted to each child's level. Addition, subtraction, division and multiplication can be added step by step. We'll definitely try the app in math class! The kids are sure to have lots of fun 😊
Original (German)
Eine tolle App, um Kindern das Rechnen spielerisch näherzubringen! Als Grundschullehrerin finde ich es besonders praktisch, dass sich die Themen und Zahlenräume individuell an den Lernstand der Kinder anpassen lassen. So können beispielsweise Additions-, Subtraktions-, Divisions- und Multiplikationsaufgaben schrittweise hinzugefügt werden. Die App wird auf jeden Fall im Matheunterricht ausprobiert! Die Kinder werden bestimmt großen Spaß haben 😊
Great app for primary school kids. The math happens “by accident” and is built right into the game.
Original (German)
Tolle App für Grundschulkinder. Das Rechnen passiert „aus Versehen“ und ist ganz natürlich in das Spiel integriert.
A great app for practising math through play! Lots of small, well-thought-out ideas, like the pause button that gives little mathematicians and gamers a bit more time. A lovely app I can recommend.

Super! Damit macht Mathe und der Umgang mit Zahlen endlich Spaß.
Math topics for grades 1–4
From first sums to fast times tables.
Pick the school year and the game builds a path of small steps. Or switch each kind of question on and off yourself.
It adapts as they play
Facts that are still shaky come back more often. Mastered ones show up less, so practice time goes where it's needed.

Parent controls and progress report
You set the topics. You see the progress.
Your area sits behind a grown-up question. Kids stay in the jungle, you stay in control.
Weekly report
What's going well, what to practise next, and the trend over eight weeks.
Choose what's practised
School year, or each topic on its own: crossing the ten, times tables, division.
Mistakes are safe
A wrong answer shows the solution and costs one heart. Then the run goes on.
Two children, one device
Each child gets their own profile, character and progress.
Parent gate
Settings and the report are protected by a question only grown-ups can answer.
Nothing to buy
Coins from the runs buy outfits. The treasure chest contents are fixed, never a lottery.
Four worlds to discover
The further they run, the more jungle opens up.
New worlds unlock by total distance, so steady practice is what moves kids forward.
Rescue animals with right answers
Every right answer helps an animal.
Eight jungle animals are stuck in the vines. Right answers set them free, one after another, and wrong ones never take progress away. Each rescued animal joins the runs with its own power.

Privacy and data
What leaves the phone: almost nothing.
Profiles, progress and the report stay on the device. The only online feature is the world leaderboard, and it shows a made-up nickname like "Swift Jaguar 27", never a real name.
Parents can switch the leaderboard off for each child. That also deletes the child's entry on our server. Read the privacy policy

Questions parents ask
FAQ
Is it really free?
Yes. There are no ads and nothing to buy in the game. Coins are earned by running and only buy outfits and characters.
Which ages is it for?
Children from 5 to 10, grades 1 to 4. Younger kids start with sums up to 10; older ones practise times tables and division until they're fast.
Does it need the internet?
No. The game plays the same without a connection. Only the optional world leaderboard uses the internet.
Which languages does it speak?
English, German, Spanish, French, Italian, Dutch, Danish, Portuguese, Ukrainian and Filipino.
Can siblings share one device?
Yes. Two children can each have their own profile, with their own school year, character and progress.
Is there an iPhone version?
Yes. Number Jungle is on the App Store for iPhone and iPad, and on Google Play for Android.
Is it safe and private for my child?
Yes. There are no ads, no chat, no account and no tracking, and progress stays on the device. The only thing that goes online is the optional world leaderboard, with a made-up nickname, and parents can switch it off for each child.
Does it adapt to my child's level?
Yes. Each child follows a path of small steps for their school year and moves up on their own once a step is solid. Facts that are still shaky come back more often, mastered ones less.
How long does a run take?
Usually a few minutes. A run ends when the hearts are gone, so it is easy to stop after one or two runs.
Does it work on tablets?
Yes. It runs on Android phones and tablets as well as on iPhone and iPad.
Can teachers use it in class?
Yes. There are no accounts to set up, and behind the parent gate a teacher can choose exactly which topics are practised, for example only the 6 times table or plus and minus to 20.
Which times tables are included?
All times tables from 1 to 10, plus the matching division. The game starts with the small tables and adds the bigger ones step by step.
Who makes Number Jungle?
Sebastian Illing, an independent developer and dad in Germany. He built it for his own two daughters and then made it free for everyone.
