Hi Explorer!
Pick a level, pick a mission and start exploring.
Choose your mission
Eleven mission bases. Each has fun facts, a hands-on animated demo you can play with, a quiz at your chosen level, and a real challenge to try away from the screen. There are lots of questions and you get fresh ones every round. Beat all three levels of a mission to earn its gold star.
Today's missions
Three quick things a day. Do them and keep your streak alive. The brain warm-up gets harder at higher levels.
Language lab
Five languages to explore: Spanish, French, Chinese, Arabic and German. Pick a language, learn a word, then try the mini challenge.
Your badges
Collect them all by finishing missions, beating every level, and keeping your streak.
Coach
I watch how you do and point you to what will help most next. The more you play, the smarter my tips get.
For grown-ups
A note for parents on what this is and how to get the most from it.
What this is
A playful learning hub for curious kids aged 6–16 who love games, animals, space, robots, building, art and sport. It mixes maths and logic, science, coding ideas, money and life skills, and five languages.
Three difficulty levels
Every mission quiz and the daily brain game come in Rookie (★), Explorer (★★) and Genius (★★★). Set the level on the Missions page, the Daily page or inside any mission. If your child is breezing through Rookie, move up to Explorer or Genius — Genius is a real stretch, with binary numbers, fractions, free-fall and multi-step money problems. Each mission tracks which levels they've beaten, and clearing all three earns a gold star.
How to use it
- 15–20 minutes a day is plenty. The Daily tab is the routine: a fact, a brain warm-up, a word.
- Missions are for weekends or when there's more time. Each ends with an away-from-screen challenge, which is where the real learning is.
- Do the challenges together when you can. Building, cooking and experiments stick far better than screens.
- Stars, levels and badges are saved in this browser, so use the same device each time — or turn on the optional cloud account below to sync across devices.
Free resources to go deeper
- Maths & coding: Khan Academy Kids, Scratch (scratch.mit.edu), Blockly Games.
- Science: NASA Kids' Club, National Geographic Kids, BBC Bitesize.
- Ocean & animals: Monterey Bay Aquarium live cams, NOAA Ocean for kids.
- Languages: Duolingo, and short cartoons in each language with subtitles.
- Music: if your child plays an instrument, try picking out the tunes behind the maths-of-music fact.
The Coach
The Coach tab quietly tracks how your child does on every quiz — which topics they ace and which they find hard — and turns that into a weekly focus and a short list of specific next steps. Over 2,500 questions are generated fresh each round across maths, coding, science, money and more, so they can keep practising without ever running out, and the difficulty grows with them from Rookie to Genius.
Make & build — where to buy components
Every mission has a "Make & build" section with crafts, kitchen science and real electronics projects. Here's how to kit out your young maker, cheapest and simplest first:
- Easiest start — BBC micro:bit. Block-coding with built-in lights and sensors, so many projects need no wiring. From microbit.org resellers, Kitronik, Pimoroni or Amazon (~€15–20).
- Best all-rounder — an Arduino starter kit. One Elegoo/Arduino kit covers nearly every electronics project here (board, breadboard, LEDs, resistors, servo, sensors, wires). From store.arduino.cc or Amazon (~€25–40).
- Individual parts (LEDs, resistors, sensors, servos, buzzers): Adafruit, Kitronik, Pimoroni, SparkFun, or AliExpress (cheapest, slower delivery).
- Anywhere: Amazon and AliExpress deliver most parts; local electronics shops stock the basics.
- Crafts & kitchen science: supermarket and a stationery/craft shop cover everything.
Safety: these projects use USB or batteries only — never mains electricity. An adult should help with cutting, hot glue and wiring.
Reading & accessibility
These help younger or still-developing readers. They apply everywhere and stay on until you turn them off. Read-aloud puts a 🔊 button on every lesson and question.
The voice that reads lessons aloud. The choice depends on this device; natural-sounding voices are picked automatically.
Cloud account (optional)
By default everything stays on this device. Create a parent account on your own Hostinger site to sync a child's progress across devices. Setup steps & files →
Signed in as
Advanced
This runs on your own Hostinger hosting (Node.js + MySQL). Accounts only work when the app is opened from your hosted site, not a double-clicked local file. Your email and an encrypted (hashed) password are stored on your server; progress stays on this device until you back up.
Your child's privacy
A child profile stores only a nickname, an age (to set the starting level) and chosen interests, plus learning progress — kept on this device by default. There is no advertising, tracking or chat. The only optional exception is the cloud account above: if a parent creates one, a parent email and a hashed password are stored on your own server to sync progress.

Grown-up PIN
The grown-ups area is locked with a PIN you chose. Change it here; it stays on this device.
Profiles & progress
Each explorer has their own profile that saves their stars, levels, streak and Coach data on this device. Switch who is playing, or add another child, any time.
Look for this explorer
The style grows up with age: playful for 6–9, balanced for 10–12 and clean for 13+. You can pick one instead.
Lessons for this explorer
Lessons are written for four age groups and picked from the explorer's age. Choose a different group if they need easier or harder material.
