Why this tool is useful

Live stream roulette picker turns a random picker into a visible marble race so draws are easier to watch, explain, and record.

Best for

Picking winners from a list of player names.
Creating a fair-looking draw screen for streams or group events.
Saving and loading custom board layouts for repeated events.

How to get good results

Enter player names, choose the winning rule, and test the board once before the real draw.
Use map settings to avoid blocked paths and make the race readable.
Enable recording only when the browser supports canvas capture.

Limits to know

Physics results depend on simulation settings and obstacle layout.
Very large maps or too many objects can reduce frame rate.

Privacy and local processingNames, map settings, and recordings are handled locally in the browser unless the user downloads or shares the exported files.

FAQ

Common questions about browser-only file conversion.

Are files uploaded to a server?No. Selected files are processed in the browser, and converted results are not stored on a server.

What should I do if processing is slow?Lowering FPS, output size, color count, or processing duration reduces browser memory use and processing time.

Can I use it on mobile?Yes, but desktop browsers are more stable for large files.
