    Some (mostly American?) people know Mahjong as a solitaire game [1] that they likely have played on their phone or Windows PC/Mac.

    This article is talking about the (arguably less known?) 4-player competitive game [2], and assumes you already know the difference (which some may not).

      Probably it’s less popular in America, but it’s huge in Asia, so I doubt the solitaire version is more well known globally

        Solitaire version should be pretty well known due to the computer game.

        Yes, but most of HN is outside Asia, so I feel the clarification is helpful here.

    I've known about Mahjong for decades but TIL it has many similarities to a game I play regularly, Rummykub. https://en.wikipedia.org/wiki/Rummikub describes it as combining elements of the card game rummy and Mahjong.

    This is a really nice website!

    In China it turns out there are lots of rule sets. The city I'm currently living in (Changsha) has it's own ruleset for example, with less tiles than these examples.

    There are so many different variations of the rules, especially scoring. Scoring can vary even from family to family.

    We've been learning for a few years now and still ignore things like prevailing winds and I don't remember what else off the top of my head. Basically we have a document of our own rules and we add to it as we get more advanced. Eventually we'll play with the winds and seasons and the goal is Hong Kong scoring.

      just played with an American friend who was learning for the first time yesterday. The winds are by far the most annoying part. Not only is the order of them different than what most people are used to (ESWN vs NESW) but the points you get for each depend on what wind you are and this is on top of having to memorize the Chinese characters (although of course some sets number them). Great game but so many little special cases that can make it intimidating to learn.

      Don't even get me started on scoring when you are gambling (although the dynamics of who pays who and how much is interesting)

    Love it!

    Question for HN: I've seen more and more of these interactive explainers popping up recently. Given these are far more approachable to build due to LLM capabilities (e.g. Claude artifacts, open generative UI, etc.), what is the community reaction around having a product tailored for creating and distributing these experiences?

    I've been experimenting over the past 6 months with interactive educational materials and curious on the community sentiment around this topic.

    Really lovely designed website.

    Though I get the sense that, typically the easiest way to learn how to play a game, is to walk through actually playing the game. Listing out a bunch of facts about how the game works is mostly just confusing for a newcomer - the brain doesn't retain that kind of information well.

    The example of this I often give is Magic: The Gathering. Very easy to learn how to play just by playing it with someone who knows. Very difficult to learn how to play if you start with a reference guide on how casting and the stack and priority and resolution works.

    > Every fan doubles your base points

    Did I miss it, or are the "base points" never explained?

    • ww520 1 hour ago
      Base point is like the minimum payout. All players agree upon a minimum payout (base point) ahead of time. E.g. $10 as the minimum for the first fan. A fan literally means doubling. A 4 fan win means the payout is $10x2x2x2=$80 from each losing party. It can go up very quickly.

    Really well made website. I played a few times in Shenzhen (slightly different rules), but it's difficult to find players willing to accommodate a beginner because Mahjong players typically play really fast (I'd say on average <1s per turn).

    Thank you for this. Playing with my in-laws I’m always completely baffled by the scoring!

    One important note I didn’t see here:

    - For league play, the scoring hands change every year!

      I think you’re thinking of American mahjong. Which I can’t understand for the life of me how it’s gotten so popular. The ratio of luck to skill is completely upside down
    • ZekeSulastin 3 hours ago
      Doesn’t that only apply to American style?
