Chinese Mahjong Rules, Scoring & Buying Guides

Chinese Mahjong doesn’t have one universal rulebook. Hong Kong families score differently than mainland tournament players, and even two Hong Kong tables can disagree on whether flowers count. This site’s default is Hong Kong Old Style (HKOS) — the version most widely played by Chinese diaspora communities in the US, Canada, UK, and Australia, and the one you’re most likely to have grown up around or be taught first. Where the international tournament standard, Chinese Official (MCR), does something differently, we say so explicitly rather than blending the two.

New to Chinese Mahjong? Start with the rules.

Chinese Mahjong has its own tile set, its own wall-building ritual, and its own calling rules — the foundation every other variant builds on. Here’s where to begin.

Why Hong Kong Style First

Hong Kong Old Style is the common entry point for most players in North America — it’s what’s most often taught at family tables, played in diaspora communities, and encountered by newcomers first. It’s also the fastest-paced, most accessible version to learn, which is part of why it became the dominant casual style across Hong Kong, Macau, and the communities that carried it overseas. If you already have house rules from family, HKOS is the most likely match.

Where MCR Fits

Chinese Official Mahjong (MCR) is the standardized ruleset built for international competition. If you’re headed toward tournament or club play, or you’ve encountered MCR at a mainland Chinese table, it’s covered in dedicated, clearly labeled articles under Variants Explained — including exactly how it differs from the Hong Kong rules this site defaults to.

Hong Kong Scoring

The fan system that intimidates every beginner.

Hong Kong-style scoring is built around fan — point values stacked from different winning patterns — plus a minimum hand requirement and dramatic limit hands at the top end. It looks complicated until you see the logic behind it.

Strategy & Tips

Beyond the rules: how stronger players actually think.

Reading discards, knowing when to stay concealed, and adjusting to the flower season all separate an experienced player from someone still learning the wall.
