Real code,
from age 8.
Your child writes real instructions. Robert carries them out to the letter. When he bumps into something, you fix it together: that's how you learn to program.
Free. No ads. No account.
On phones, tablets and computers, even offline.
It all started in a workshop.
Robert is an inventor. One night, a tiny mistake in his code opens up a really big hole…
One night, in his workshop…
Oh, hi! My name is Robert. I love building and programming machines.
Here's my latest invention: the Exploroid. Just one more line of code and I'll be able to launch it…
Oops. A little mistake… and a really big hole that's sucking up eeeeverything!
Somewhere in space…
Ouch… my skills are slipping away. And so are the gears of my Exploroid!
I can still walk, turn, and pick things up. But I can no longer make decisions on my own.
You, on the other hand, do know. Tell me what to do, and I'll do it exactly as you say.
Help me get home by regaining my skills and finding the gears of my Exploroid.
What happens next? Your child writes it…
How it works.
Four steps, always the same. That's how you learn to program.
Your child types real instructions: move, turn right, pick. Then GO, and Robert carries them out to the letter, line by line.
Robert bumps into something, and he says what happened. Mistakes are never punished: you reread your program, change a line, and run it again.
A level really won't budge? Robert shows the path, as a hologram. The code is still left to write: your child is the one who finds it.
The level is complete, and the stars say why: reached the end, a short program, the shortest possible. It makes you want to do even better.
On tablets too.
The first level takes your child by the hand: Robert shows what to type, letter by letter, then lets them write on their own.
On phones (Android app or browser), tablets or computers.
The first level is waiting for you.
Play nowEvery star counts.
No ads, no purchases: whatever you earn in Cosmobert, you earn by programming.
- 126stars to earn, three per level. One for reaching the end, two for a short program, three for the shortest.
- 1hint token for each level completed with three stars. When you're really stuck, a token reveals the code.
- 7rewards unlocked with stars: four costumes for Robert and three themes that change the colors of the whole game.
Six planets. 42 levels.
Four of Robert's skills are scattered across these planets. Which ones? We won't say: you'll find out by playing.
- The Plain
- The Corridor
- The Harvest
- The Void
- In Your Footsteps
- The Great Whole

For parents: see everything, share nothing.
The “Your Adventure” page shows this week's playing time, the stars earned and the planets completed. It stays on the device, like everything else.
- No account, no name. Install it and play. The app asks your child for nothing.
- No ads. No ads, no purchases, no data about your child.
- Everything stays on the phone. The game goes nowhere; you can save it to a file.
- Works offline. In the car, on vacation, anywhere.
For teachers: after blocks, typed code.
Your students move from blocks to typed code, guided by a character. Nothing to install in class: the game also runs in the browser.

Translated from French.
“In class, every year I see students get stuck when it's time to move from blocks to written code. My son was one of them: typing an instruction scared him. With Cosmobert, he wrote his first lines without even realizing it. Robert shows him exactly what each instruction does, and a mistake becomes a game rather than a failure. Today, he asks to play every evening.”
“When Robert bumps into a wall, it makes me laugh so much. Then I look for the line that's wrong, and off he goes again!”
“I got all three stars on the whole first planet. Now I want the Lion costume for Robert.”
Robert is counting on you.
The first level takes just a few minutes. The rest of the story is in the game.
