Platform sketch
A lightweight code-first lane for drawing, movement, and quick two-dimensional game ideas.
You design the game. Maady writes the code.
Describe your idea in plain words, click your world into shape, and smash RUN. GameCoder's robot co-builder turns imagination into a real, playable, shareable game.
- Runs on Chromebooks
- Kid-safe & ad-free
- Real code under the hood
Coin Quest
Maadywrites the code for you
Coin Quest looks great! Your player can already run and jump. What next?

Done — grab the coin and watch it spin!

How building feels — from idea to RUN in seconds.
How it works
Three moves. One real game.
You make the creative calls — Maady sweats the semicolons.
Your idea
Describe it
Tell Maady the game in plain words. It asks smart questions, then writes the real code — and shows you exactly what changed.
“make a cat that dodges flying tacos”
Your design
Design it
Click anything on the stage to move it, resize it, and give it powers — spin, bounce, arrow keys. You are the art director here.
“drag the coin, give it Spin, done”
Your game
Play it
Smash RUN and play it on the spot. When it feels right, publish to your class library and friends play in the browser.
“send it to the class library — one click”

Questions
Answers before you ask
Where do student games live?
Every project starts private. When it is ready, students publish to a signed-in school library — not an anonymous public gallery.
Is there real code underneath?
Yes. Projects run on real p5.js, Phaser, or Three.js code, and students can open and edit that code any time.
What do students need to run it?
A web browser. GameCoder runs on Chromebooks, iPads, and shared library computers — nothing to install.
Can strangers talk to students through GameCoder?
No public social or stranger-contact model is part of the default school rollout.
What happens if a game should be taken down?
Teachers and admins can review, unlist, or remove published games, and families can route concerns through the school and the support page.
