🀄 Hyloveclub - 上海老麻將（13 張）
📖 上海老麻將玩法、番數與成葫
本版：136 張、每人起手 13 張，莊家先摸第 14 張；胡牌必須四副牌加一對麻將、七對子或十三么，並符合基本 11 番門檻或「成葫」牌型。沒有花牌／寶牌。
番與葫：1 番＝500 籌碼，2 番折合 1,000 葫，總番數÷2 四捨五入（例如 11 番＝6,000 葫）。符合「成葫」的牌型以固定葫數計，不另加番。
| 1 番（部分） | 將牌 258、對碰、卡五、暗嵌一組、槓一組、莊家、自摸（非門清） |

版本界線：已實作一般和牌、七對子、十三么及多項主要番種／成葫牌型；其餘罕見牌型（如十二金釵、九蓮寶燈、相公復活、全包牌與特殊搶槓）尚未完整自動處理。成葫間若有包含關係，遊戲以較高的組合牌型取代基礎牌型；不含包含關係的其他成葫可累積，這屬電子版的暫定去重方式。以原始文件為準。原表「800,00 葫」此版暫解讀為 80,000 葫，請以作者核定版本為準。尚未自動執行八圈座位交換及連莊費用；目前可連續進行多手練習。
Shanghai Old Mahjong — Rules by Ching Lee
Traditional no-bonus version: 136 tiles (Characters, Dots, Bamboos, Winds and Dragons); 13 concealed tiles per player, with the dealer drawing a 14th tile to begin. This is not Taiwan 16-Tile Mahjong. In this digital adaptation the aim is four melds plus one pair, Seven Pairs or Thirteen Orphans, with an ordinary minimum of 11 fan or a qualifying special Cheng Hu (成葫) hand. The optional eight Flowers/Seasons are excluded here.
Basic play: Take turns drawing one tile and discarding one. You may Chow a run from the player just before you, Pung an identical discard with two matching tiles, and Kong with three or four matching tiles. Declare a win with the Win! button when the displayed rules permit it. Pass declines an offer. The computer plays the other three seats.
Fan and Hu (葫): One fan is 500 virtual chips; two fan equal 1,000 hu. To settle an ordinary qualifying win, divide total fan by two, round halves up, then multiply by 1,000. Thus 11 or 12 fan each pay 6,000 hu. Special high-difficulty hands have fixed Cheng Hu amounts, replacing—rather than adding to—ordinary fan scores.
| 1 fan (selected examples) | Dealer, 2/5/8 pair, one concealed pung, one kong |
| 2 fan (selected examples) | All Chows, All Simples, No Fives, Missing Suit, matching chows |
| 3 fan (selected examples) | Concealed Hand, two concealed pungs, two kongs |
| 7 fan (selected examples) | Half Flush, All Five Categories, Seven Pairs, concealed self-draw special bonus |
| 9 fan (selected examples) | All Pungs, Pure Straight |
| 20,000 hu (examples) | Little Three Dragons, Wan Fu, Chang Lu, Yuan Shou, Three Wind Pungs |
| 40,000 hu (examples) | Full Flush, Big Three Dragons, Little Four Winds |
| 50,000 hu | Full Flush All Pungs, Big Three Dragons All Pungs |
| 60,000 hu (examples) | Thirteen Orphans, All Terminals and Honors Pungs |
| 80,000 hu (examples) | Big Four Winds, All Honors Pungs |
Settlement: On self-draw, all three opponents pay the winner the full hand value. On a discarded-tile win, the discarder pays the full amount and each other nonwinning player pays half. Every player starts with 300,000 practice chips; there is no gambling or real money.
Important limits: This is an introductory digital adaptation, not a complete formal implementation of every original rule. Some rare named hands, liability/payment exceptions, robbed-kong cases, kong recovery, full eight-round seat exchanges, and dealer continuation charges are not automated. The game uses provisional logic when overlapping special hands qualify; please refer to the original document for authoritative scoring.
