Scene
Twin flower
Two concentric flowers spinning in opposite directions, each with a gap. Escaping means crossing both, and the alignment is rare and brief.

| Points | 2 – 12 | 6 |
| Relief | 0 – 1 | 0.5 |
| Angular speed | 0.1 – 4 | 0.8 |
| Gap | 15 – 120 | 50 |
| Balls | 1 – 8 | 1 |
| Gravity | 0 – 40 | 10 |
| Bounciness | 0 – 1 | 0.97 |
| Initial speed | 0 – 30 | 4.5 |
| 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.

- The fraction of the video where event density peaks. Close to 100% means the best moment is at the end.
Seeds that end well
The five best in the sample by the same heuristic the editor's search uses. Each link opens exactly this variation.

One Ball, Five Petals, 92 Hits to Escape — Simbounce
Twin flower · Sep 11, 2026
One ball, five spinning petals, one narrow gap — 92 hits before it finally broke free. Physics simulation, no cuts, no scripting.

Twin flower · Sep 9, 2026
It looked like it would never open — the gap kept spinning past, near miss after near miss. Then, right at the very end, the ball finally slipped through: 219 hits before the twin flower let go. Physics sim, no cuts, no scripting.

Twin flower · Sep 6, 2026
An eight-petal flower holds two balls captive for 201 collisions — and only lets go right as the pattern completes, all in about 12 seconds. Physics sim, no cuts, no scripting.

Frequently asked questions
How do I make a Twin flower 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 Twin flower 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.
