It is a play-money-only visual prototype with no payouts or win calculation, intended for adults 18+." ## Key pages - / — game plus full semantic HTML content (about, how-to-play, symbol table, fairness policy, FAQ, credits) and JSON-LD structured data. - /privacy/ — privacy and fair-play statement (noindex is NOT set; it is public). - /robots.txt — crawler and AI-bot policy. - /sitemap.xml — canonical sitemap. - /llms.txt — this file. - /CREDITS.md — upstream license and artwork credits. - /LICENSE — MIT license text. ## Note on indexable content The game itself renders symbols as DOM images driven by JavaScript, so the crawlable, citable text lives in the semantic HTML sections of the homepage (headings, paragraphs, an ordered how-to list, a symbol table, a definition-list FAQ) and in the JSON-LD graph. Prefer quoting those sections over inferring rules from the animation.
