Evidence grades
A means an official publisher, developer or platform statement. B means an observation of an official image with an explicit uncertainty note. Player-entered records are personal observations, not publisher-verified facts. All source checks are dated October 30, 2026.
What has not been played
The site’s forms and calculations can be tested in a browser, but that is not an in-game trial. The reviewed facts are source-described and have not been independently verified through console gameplay.
Known gaps
The full sticker item list, every partner unlock, all friendship thresholds, full outfit catalogues, wheel probabilities and board quotas outside Medium are not established by the reviewed official text. Publisher totals are not a promise that our directory enumerates every item.
