How are random results chosen?

Each draw starts with a cryptographically random browser seed. Fixed-step physics determines arrival order, and the same seed and input reproduce the result. Stuck marbles get a small nudge. At the time limit, remaining marbles rank by closeness to the finish, then input index.

How do shared links and input privacy work?

Opening a link replays the same marble drop. It contains only names or a number range, mode, course settings and seed; results are recalculated. Default course settings are omitted. Number ranges keep links short without storing names. URL hashes are not sent to the server.

Entries and names are processed only in your browser and are not sent to a server. There is no server or database storing game inputs or results.
