Mahjong: A Visual Guide

Beautiful Mahjong guide lands; players cheer, purists nitpick, newbies beg for slower turns

TLDR: A slick visual guide explains Mahjong’s tiles, 4-sets-and-a-pair win, and score-doubling bonuses. Commenters love the design but clash over teaching-by-play vs info-dumps, warn that rules vary and leagues change scoring yearly, and debate whether AI-made interactive explainers should become a product.

Mahjong just got a glow-up. A new visual guide breaks down the 136 tiles (three suits plus Winds and Dragons), the classic win condition — 4 sets + 1 pair — and the wild fan system where each bonus doubles your score. Design lovers swooned, with one commenter cheering it’s a “proper” guide. But then the tiles started flying in the comments.

Teaching style became the table-flipper. Wavemode argued that dumping facts is confusing and that newbies learn best by playing through a hand — citing Magic: The Gathering as the gold standard. Others piled on with real-world reality checks: in places like Shenzhen, rules differ, and veterans blitz turns in under a second, making beginners sweat. Cue jokes about dragons on espresso and pleas for a “slow mode” table.

Rule sticklers showed up, too. Nyanmatt warned that in many leagues, scoring hands change every year, so don’t tattoo the rules just yet. And in a meta twist, FarhadG asked if these sleek explainers should become a product category now that LLMs (large language models) make them easier to build. The vibe: a gorgeous guide everyone wants, a brawl over how to actually learn, and a side quest about turning tutorials into a business. Read the room, then read the guide

Key Points

  • A mahjong set has 136 tiles: 34 unique designs (four of each), with three suits (1–9) and honor tiles (four Winds, three Dragons).
  • A winning hand is 4 sets plus 1 pair for a total of 14 tiles; sets are chow, pung, or kong, and players usually hold 13 until completing the hand.
  • Scoring uses fan (fān), where each fan doubles base points (e.g., 3 fan = 8×, 6 fan = 64×), stacking on top of a win.
  • Tiles are built into a square wall; dealing and drawing proceed counter-clockwise, with the dealer determining the wall break via dice and starting with 14 tiles.
  • The last 14 tiles form a dead wall for kongs and replacements; declaring a kong draws from it, and an exhausted live wall without a winner results in a draw.
