    for this variant The later edition, issued by the WMO as the unified standard for referees (its announcement of 26 November 2014). It leaves the scoring table as it was in 2006 and moves the wording in one place in the penalty rules.

Reading it

The scoring reference is primary-sourced and corroborated. The 2006 Green Book, the 2014 edition, the 1998 text, Japan's JMSA list and Moegirl's table agree on the frame: 81 fan in nine series, twelve grades from 88 to 1, an 8-point minimum that flowers do not count toward, and the counting principles. The editions differ in detail. Two Concealed Kongs is 6 points in the 1998 book (seen in the MIL's page scan, p. 26) and on JMSA's list, but 8 in the 2006 Green Book. Japanese Wikipedia says the 2006 rules changed several values and combinations and were not a formal revision. The EMA's 2015 minutes say most Chinese players kept to the 1998 rules, and Moegirl says the same of online platforms. Tournaments amend how the table is used. The EMA's regulations (2010) and penalty sheet (2009) set the false-hu penalties at 10 or 20 to each opponent, restrict counting with flowers, and void wait fan when the winning tile is not shown. The 2026 WMC applies the MCR as it stands. Japanese practice may drop flowers, cap fan at 88 or score a mixed kong pair at 5. The Japan Kenko Mahjong Association claims a hand in cutting 400 patterns to 81. Still wanted: the EMA Referee Manual and the WMO's 2014 beginner rules.

Looked for, not found

  • Law No law governs MCR scoring. The rules belong to a sports body (the WMO, or China's General Administration of Sport in 1998), and no channel turned up a statute.
  • Historical The table has no history before 1998. The only accounts of its drafting are the 1998 preface, Chinese Wikipedia (read earlier) and the Japan Kenko Mahjong Association's retrospective (read here, filed as organisation).
  • Scholarship No academic study of the MCR scoring table was found in this pass or earlier ones. The scholarly indexes were not searched (OpenAlex wants a key).
  • Journalism Only mj-news.net's column 「中国麻将の役・ルール紹介（1）」 (2018) turned up. It is a readable lead, left unread for budget; no newspaper coverage of the table itself was found.
  • Forum Not searched: Reddit and BoardGameGeek refuse automated readers. The counting disputes are documented by Starbäck and the WMCC Explanation, and Sloperama's columns are by the chart's own author.
  • Commercial App Store listings ('国标麻将-超级工具', 'i.Game 中国麻将 Lite') and the Takeshobo rulebook are known; none was read. The rulebook is on the wanted list.
  • Collection No museum or library record bears on the scoring table; it is a rule text, not an object.

It is probably where referees' scoring rulings are written down.
    Where: European Mahjong Association (mahjong-europe.org); EMA-certified referees. Tried: Not linked from the EMA's MCR rules page or its regulations page (both read 2026-10-14); a web search for it returned only third-party summaries (an Xmind penalty template).
  • Official rules World Mahjong Organization, 国际麻将竞技初级规则 (International Mahjong Competition Beginner Rules), 2014 — According to Japanese Wikipedia, the one official cut-down version of the table: fewer fan, a 6-point minimum and no 8-point base payment.
    Where: chinamajiang.com/htdocs/pages.asp?id=28 (cited by Japanese Wikipedia); the WMO / World Mahjong Contest Center. Tried: chinamajiang.com answered with its own 403 on 2026-10-14. The Wayback CDX query returned the Internet Archive's 'Temporarily Offline' page, a failure on the archive's side, so it is worth trying again.

31 places searched
  • General web search — Searched 2026-10-14, standard mode seven times and extended once (Japanese). English queries on EMA scoring policy found nothing on mahjong. A query on WMC regulations found the 2006 rulebook mirrored on mahjong.dk, Sloperama's MCR_ERRATA14.doc and keyword-stuffed spam pages (fightcancer.org, internationaltrucks.com). A Japanese query found the 8th WMC regulations on mahjong.dk (read). Chinese queries found Moegirl (read), Bilibili posts, 18183.com and an App Store listing. The extended Japanese query found JMSA and the Japan Kenko Mahjong Association (both read), Japanese Wikipedia (read), and unread pages: mj-news.net's column 「中国麻将の役・ルール紹介（1）」, note.com (日本プロ麻雀協会), Ameblo, Niconico Daihyakka, mjlocal.fandom and 1chinese.com. Also read, not observed: the EMA's 2026 tournament guidelines, whose PDF text is broken by zero-width characters. They say the MCR is amended for Europe by the Tournament Regulations and the Referee Manual, and that a substitute scores 0 table points and 0 points.
  • Wikidata — The API answered 429 on 2026-10-14, but Special:EntityData/Q834013.json answered. Sitelinks: zh 国标麻将, ja 中国麻雀, fr Règles de compétition du Mah-jong. Labels: en Competition Mahjong, zh-hant 國標麻將, ko 국표마작. Aliases: en 'Competition Mahjong scoring rules' and 'Guóbiāo Májiàng'; ja 麻将 and 中国麻将. There is no English article. French and Korean were not added to names: only the French article and a Korean label were found.
  • Wikipedia, in every declared language — Japanese 中国麻雀 read as raw wikitext through index.php?action=raw, because the API answered 429 all through the pass (2026-10-14). Chinese 国标麻将 was read in an earlier pass and not re-read. French 'Règles de compétition du Mah-jong' exists but was left unread (budget). English Wikipedia has no article on this item.
  • The sources' own references, and who cites them — Japanese Wikipedia cites chinamajiang.com/htdocs/pages.asp?id=28 for the 2014 beginner rules: the site answered 403, and Wayback CDX returned the Internet Archive's 'Temporarily Offline' page (2026-10-14). Its external link to mindmahjong.com showinfo id=977 was read. The EMA MCR page and the 2026 guidelines name a Referee Manual that no page links. The MIL's International Rules page links the 1998 book as an image scan: pages 24 and 26 were looked at, but there is no text to quote. Leads for a second round, unread: the WMO's 20141120CEJ.pdf (probably the 2014 edition already read from ooyamaneko.net), JMSA's Chinese and English fan-name page, the addenda to the EMA's 2015 minutes, the French Wikipedia article's references, and Sloperama columns 293c and 296c.
  • Internet Archive full-text search — An advanced search on 'Mahjong Competition Rules', 中国麻将竞赛规则 and 国标麻将 (2026-10-14) returned 80 hits, all unrelated, because the Chinese terms were tokenised (ChinaXiv papers, Bilibili mirrors). The full-text endpoint returned nothing usable.
  • Wayback Machine — The canonical mcr_EN.pdf answered directly on 2026-10-14, so the Wayback Machine was not needed for it. CDX lists captures of mindmahjong.com showinfo id=977 from 2014, 2016 and 2019. A CDX query for chinamajiang.com returned the 'Temporarily Offline' page.
  • Google Books — Not searched: the API answered 429 in earlier passes, and the print sources of the table (the 1998 book, Takeshobo 2002) are already known.
  • HathiTrust full-text search — Not searched: full-text search is behind a Cloudflare challenge, and the table's print editions are already identified.
  • WorldCat — Not searched this pass: the parent node already records OCLC 768652206 (the 1998 book) and 276447975 (Du Weizhong's guide).
  • Scholarly indexes — Not searched: OpenAlex wants a key, and earlier passes found no academic study of the MCR scoring system.
  • YouTube — Not searched: tournament broadcasts show play, not the documents that amend counting.
  • English-language forums — Not searched: Reddit and BoardGameGeek refuse automated readers. The disputes over counting are covered by Starbäck and the WMCC Explanation, read earlier.
  • Mahjong reference sites — Moegirlpedia's 麻将/番种 was read (Chinese, independent of the chart). Sloperama's MCR_ERRATA14.doc and columns 293c (Tianjin clarifications) and 296c (kongs and pungs) turned up but were left unread: they are by the chart's own source author. mjlocal.fandom's 中国麻将競技規則/番種分値表 was left unread. The Mahjong Wiki was not re-read.
  • App and platform listings — Search results listed '国标麻将-超级工具' (App Store id1630500568) and 'i.Game 中国麻将 Lite'. Neither was read: an app's rules page would restate the table, not show how tournaments amend it.
  • English-language newspaper archives — Not searched: the table dates from 1998 and has no press coverage of its own; earlier passes found none.
  • Statutes published in English — Not searched: no statute in an English-language jurisdiction governs MCR scoring; the rules are a sports body's.
  • Baidu search and Tieba — Baidu has no open API. Stood in for by two Chinese queries in the general search (2026-10-14), which returned Moegirl, Bilibili, 18183.com and App Store pages, and no mainland tournament regulations.
  • Baidu Baike — Not searched: Baidu Baike answered 403 to automated readers in earlier passes.
  • Chinese Q&A and community sites — Not searched: Zhihu answers 403 and Xiaohongshu has a login wall; Moegirl stood in for Chinese community writing.
  • WeChat public-account articles — Not searched: Sogou WeChat search has no open API. Mainland tournament notices that amend counting may be there; noted for a manual search.
  • Bilibili — Two Bilibili opus posts on counting fan turned up in the general search (888598475540791367, 1193442755832971266). Not read: they are individual write-ups.
  • Pre-modern and Republican Chinese texts — Not searched: the table dates from 1998, so pre-modern and Republican texts cannot bear on it.
  • Chinese-language scholarship — Not searched: no study of the scoring table turned up in earlier passes, and CNKI abstracts are not reachable from here.
  • Chinese-language newspaper archives — Not searched: Chinese press of 1998 was not found online in earlier passes, and the scoring table has no news history of its own.
  • Statutes published in Chinese — Not searched: the 1998 rules are a sports body's competition rules, not a statute (see the parent node).
  • Yahoo! JAPAN search — Searched 2026-10-14 with two standard queries and one extended query in Japanese. Found and read: JMSA's yaku list, the Japan Kenko Mahjong Association's 国際公式麻将 page and Japanese Wikipedia. Found and left unread: mj-news.net's column, Ameblo's 「5分でざっくり中国麻雀（国際公式ルール）」, 1chinese.com and Niconico Daihyakka.
  • National Diet Library — Not searched this pass. The Japanese rulebook (Takeshobo 2002) is already wanted, and Japanese Wikipedia mentions other Japanese-language rulebooks, which are left for an NDL search.
  • Japanese scholarship — Not searched beyond the general search, whose one CiNii/IRDB hit (ouc.repo.nii.ac.jp) is about Taiwanese sixteen-tile mahjong.
  • Japanese professional leagues — JMSA and the Japan Kenko Mahjong Association are the Japanese MCR bodies found; both pages were read. The association runs an annual MCR series (国際公式ルール無双位戦) whose regulations were not found. A note.com article by the Japan Professional Mahjong Association (日本プロ麻雀協会) on promoting 中国麻将 was left unread.
  • Japanese community writing — Niconico Daihyakka's 中国麻雀 and an Ameblo explainer turned up and were left unread (budget). mjlocal.fandom's 番種分値表 is noted under mahjong-references.
  • Japanese statutes — Not searched: no Japanese law addresses the MCR scoring table.
