Scene
Escape the ring
A ring with a spinning gap. The ball only escapes when the gap lines up, and the spin speed decides the suspense.

Parameters
The same controls as the editor, with the same range. The default is what the example page uses.
| Parameter | Range | Default |
|---|---|---|
| Gap | 2 – 120° | 28 |
| Angular speed | -8 – 8rad/s | 1.1 |
| Balls | 1 – 12 | 1 |
| Gravity | 0 – 40 | 12 |
| Bounciness | 0 – 1 | 0.94 |
| Initial speed | 0 – 30 | 5 |
| Growth per collision | 0 – 0.2 | 0 |
How it usually ends
Measured by the engine with the default configuration over a fixed sample of seeds. No number here is an estimate.

A 14-Degree Gap That Wouldn't Line Up — Simbounce
Escape the ring · Sep 12, 2026
A rotating ring with just a 14-degree gap kept sliding past the ball's path, again and again. It took 69 hits — and a climax three-quarters of the way through — before the opening finally lined up. Physics simulation, no cuts, no scripting.

One Gap, One Ball, Almost No Time — Simbounce
Escape the ring · Sep 10, 2026
A single ball hunts a twelve-degree gap in a ring spinning too fast to time — 23 hits before it finally slips through, right at the very end. Physics sim, no cuts, no scripting.

Two Balls Trapped In A Spinning Ring — Simbounce
Escape the ring · Sep 7, 2026
A spinning ring holds a narrow 20° gap — the only way out. Two balls take 36 hits before one finally slips through, with the opening barely lined up in time. Physics sim, no cuts, no scripting.

Frequently asked questions
How do I make a Escape the ring video?
Open the scene in the editor, adjust the parameters, try a few seeds and export to MP4. Rendering happens in your browser and costs nothing.
Why does the same seed always give the same video?
The simulation is deterministic: fixed-step physics and seeded random numbers. The same seed with the same parameters reproduces the same video on any machine.
How long is a Escape the ring video?
The video ends when the scene ends. The median duration measured in the sample is in the outcomes section, and the seed search shows each candidate's duration before rendering.
Can I use the video on TikTok, YouTube and Instagram?
Yes. The export is a vertical video with audio, ready for Shorts, Reels and TikTok. On the free plan it carries a discreet watermark.
How do I pick a seed that ends well?
Use the editor's seed search: it simulates dozens of variations without drawing and ranks the ones with a late climax. The seeds on this page came from the same heuristic.
Make your own variation
Open the scene in the editor with one of the seeds above, or let the search find another.
