Write to contact@gospinit.com — it reaches a person who has, at minimum, strong opinions about wheel physics.
A device where the wheel stutters, mislands or goes quiet — name the browser and roughly how many entries were on it. A classroom or giveaway routine we should support better. A wheel with hundreds of saved lists (we want to hear how you organize them). Feature requests in general: elimination mode exists because someone asked.
Disputes about who a wheel picked — the draw is cryptographically fair and we keep no copy of it, so there's nothing for us to review or overturn. The winner history on your own device is the record of your draws; that's by design.
