Predict first.
Then find out.
Every project opens with a guess, and the guess is worth shells whether it turns out right or wrong. That is the difference between a child watching science and a child doing it.
In build Being written now. The path below is what is coming.
Two lemons instead of one. What happens to the voltage?
Say your guess before you wire it
No hint yet — a guess is worth shells whether it lands or not. Tell me what you think first.
A sample, not a live game. Pelo hints and cheers — he never chats.
Five stages, three to eighteen
Not five difficulty settings. Each stage changes the reading level, the length of a round, how quickly Pelo offers a hint, and what the whole thing looks like.
Three decisions worth explaining
A guess is paid for, right or wrong
Rewarding only correct predictions teaches children to guess safe. The shells arrive for committing to an answer, which is what a hypothesis is.
It ends off the screen
Roughly half of every project finishes with something built from what is already in the house. Anything needing heat, blades or chemicals asks for a grown-up before it will unlock.
A lab book that fills up
Predictions, photographs and results collect in one place. By fourteen a child has years of evidence that they can build things.
What a child actually does
We did not build five hundred unrelated games. We built fifteen game types any subject can fill, which is why the twelfth academy costs a fraction of the first.
Guess box
Commit to an outcome before anything moves.
Virtual lab
Wire it, mix it or drop it with nothing at stake.
Build it for real
A printable card and the things in your cupboard.
Show and tell
Photograph it. Pelo asks what surprised you.
Most apps adapt the difficulty. Zupelo adapts everything else too.
The pitch of a question is the easy part. What changes underneath is which skill comes next, how it is explained, when a hint arrives, how long a session runs, and what a wrong answer is taken to mean.
Science & STEM shares that engine with the other eleven. A day spent on science keeps the same streak as a day spent anywhere else, because losing interest in one subject should never cost a child the habit.
How the engine picks🐚 One currency
Shells, earned for finishing and for coming back — never for being right. They cannot be bought and cannot be converted.
🔥 One streak
Any academy keeps it going. Miss a day and a streak save covers it, on every plan including free.
🔒 No leaderboard
There is no global ranking and no public profile. Comparison is with your own last week, or with friends a grown-up approved.
Every child learns differently.
