Sims
SimFrame around each sim-core machine. Journey of a request: the 3D view loads lazily; phones with saveData, weak GPUs and reduced motion start in 2D. Flip the break-it switches and press Send. The terminal is text only, so it has no 3D view and no zoom.

Playground
HTML, CSS and JS in CodeMirror, run in a sandboxed frame (scripts only, no same-origin, no network). Side by side when there is room; a Code / Preview / Console switch on phones. Ctrl+Enter runs.
Playground
No tests. Press the button in the preview: its clicks show in the console.
<h1>My page</h1> <p>Press the button.</p> <button id="go">Count</button>
body {
font-family: system-ui, sans-serif;
padding: 16px;
}
button {
padding: 8px 16px;
}
let clicks = 0;
document.getElementById("go").addEventListener("click", () => {
clicks = clicks + 1;
console.log("Clicked", clicks, "times");
});
console.log("Ready");
An endless loop
The loop guard stops it after a second with an error in the console. The page never freezes.
console.log("Starting");
while (true) {
// nothing ever stops this
}
<p>This page has a loop that never ends.</p>
Tests
- No errors in the console.Not run
ChallengeRunner: fix (with AI tip)
Public tests run in the preview; the lock marks a hidden test the api checks. 'Ask for a tip' gives one short hint at 0 points cost.
This page has two bugs. Fix them so the heading is navy and the text sits under it.
<h1>Hello <p>Welcome to my page.</p>

colour: navy;
}
Tests
- The heading says Hello.Not run
- The paragraph is not inside the heading.Not run
- The heading is navy.Not run
- There is still one paragraph.Checked when you send
AI tip: The heading tag is still open in HTML, and CSS uses the spelling color.
Next step: Close the <h1> tag before the paragraph starts.

Explain
An open answer in the learner's own words, graded by AI against a 0-3 rubric on the api (screened first; the text is fenced off as data). Points are score/3 of the cap. The host can change any score.
ChallengeRunner: explain (with voice)
Type or record up to 60 s. The dev mock fills a sample transcript and grades 2 of 3 on the first try, then 3 of 3.
In your own words: what happens between typing games.gb and seeing the page?
A good answer covers:
- Where the address comes from
- Who the browser talks to
- How the page gets back to you
Your recording is turned into text by our AI service and then deleted.
0 / 400
Pending
AI off, slow, failed or over a cap: the answer is saved and the host scores it. The learner is never blocked.
