FAQ 2b. Identifying a Mah-Jongg Variant

Before You Buy A Mah-Jongg Set or Book, Make Sure You Buy The Right Thing

Like it says in FAQ 1, Mah-Jongg is played in many different ways. The first thing you have to do is make sure you know which kind of mah-jongg you want to learn.

a. So, if you are new to mah-jongg, first you need to choose a rule set to study.
b. If you are already playing mah-jongg, and are not sure which of the 30+ known varieties of mah-jongg you play, it's helpful to have a name to put on it. Especially if you have a question to ask about your variant on our Q&A Bulletin Board.

This FAQ will help you with both. Click the following links to jump to the appropriate section of this FAQ.

How to find out which version of Mah-Jongg you [or your friends] play.

If you have friends who play Mah-Jongg and you want to get a book so you can study up on the way they play, you have to first know which version of Mah-Jongg your friends play. There are two problems with this:

A. Most people who play Mah-Jongg are unaware that there are more ways to play. If you just ask them "which style Mah-Jongg do you play?" they may give you a blank stare (or they may give you an imprecise answer). So you may have to ask in a different way (described below).

B. Very few books on Mah-Jongg make it clear which variety of Mah-Jongg they describe. The books too seem to have this attitude that there's just one way to play. In order to find the proper book, you can refer to the books FAQ (once you know which flavor of Mah-Jongg you want to study).

C. There is no one established standard naming system for the various flavors of Mah-Jongg. Different authors use different names to refer to the same style of Mah-Jongg. The naming system used here is just the naming system that this author chose.

To find out which game your friends play (or to identify the version you are already playing), start by asking your friends a few simple questions:

1. Do you use a card that changes every year?
- If yes, your friends play American (probably NMJL), and you can stop asking questions. All other varieties of Mah-Jongg use constant rules that stay the same from year to year.

2. How many tiles do you hold in your hand during play? 13 -- or 16? (When you win, do you go out on 14 tiles -- or 17?)
- If your friends say they play with 16 and go out on 17, then your friends play Taiwanese or Filipino style, and now you only have to ask one more question: "when you get a Wind or Dragon do you keep it in the hand and make groups of them, or do you treat them like flowers?"
- If they treat winds and dragons as flowers, then it's Filipino. Otherwise, it's Taiwanese. Also, it's likely that if you've narrowed their game down to Filipino or Taiwanese, you could simply ask, "Do you know if it's Taiwanese? Or Filipino?" Most likely, when you ask this question, the person will look puzzled briefly, then say "Well, the person who taught me the game was from Taiwan" (or the Philippines), and you will have your answer.
All other styles use 13 tiles in the hand, winning (going out) with 14 tiles in the hand.

3. Do you use "Reach" and "Dora"?
- If yes, your friends play Modern Japanese style, and you can stop asking questions.

4. How many tiles do you use when you play?

144: Your friends could play any of a variety of styles. Hard to tell; see below.
152: They probably play American (most likely NMJL).
136: They probably play Japanese, or maybe Chinese or HK but without the flowers.
160 or more: Vietnamese, or maybe Thai style mah-jongg (about which little is known).
108: Hunan style or Malaysian 3-player "B".
132: Fuzhou style.
104: Korean (3 or 4 players).
84 or 88: Malaysian 3-player "A".
72: Szechuan style.

The main problem with that last question is, of course, that most people never bother to count their tiles. And most people do not want to go through all the work of figuring out how many tiles they used just to satisfy your seemingly unending barrage of questions. But in fact this is the last question that can be asked to easily identify a style of mah-jongg. There is another way to ask it: how long is each player's wall? If it's 17 stacks long, then 136 tiles are in use. If the wall is 18 stacks long: 144 tiles. If it's 19 stacks long: 152 tiles.

4. How many flowers / jokers are in use?

In May of 2016, Raymond Lee provided the following table showing types of flowers and jokers used in different Chinese and Southeast Asian variants:

For more on the variants Hua Maque and Wang Maque, see the learned research of Michael Stanwick and Hongbing Xu at mahjongtileset.co.uk. And for more about the difference between "general jokers" and "special jokers," see FAQ 7E, the "mystery tiles" FAQ. In the table above, "Animals" refers to what I call "Singapore flowers," also described in FAQ 7E.

5. Are the players all female and caucasian?
If so, your friends are probably playing American or Western/British (which includes Wright-Patterson, Australian, and India/Mumbai styles).

6. Is a substantial portion of the other players of Asian descent?
If so, your friends are probably not playing American or Western/British. They are playing one of the other variants.

If you have not yet identified which style your friends play, they may play Chinese Classical, Chinese Official, Hong Kong, New Style, Malaysian. . . to name a few possibilities. So below I describe the main characteristics of all the major varieties of Mah-Jongg which I can describe as of this writing, and you can figure out the questions from there. Don't stop reading before you get to the bottom. Variants are usually mentioned numerous times.

Note: the names of the various flavors of mah-jongg are not necessarily universally recognized. Some authorities may call a particular style of mah-jongg by a different name.

Detailed overview of the major varieties of mah-jongg

Flowers are used in the hand (you can pung and kong them).

Only the winner is paid.
Books: NMJL (see FAQ 3, the books FAQ).
Many people refer to American mah-jongg as "Jewish Mah-Jongg." I object to this as being not completely accurate. Although a majority (somewhere between 60% and 80%) of the players are Jewish, there are quite a lot of non-Jewish players of American mah-jongg. Approximately 98% of the players of American mah-jongg are female. So perhaps it would make more sense to call it "Womens' Mah-Jongg" than to call it "Jewish Mah-Jongg." Some authorities use the term "American Mah-Jongg" in reference to Western (British Empire) style. And Wright-Patterson also is distinctly an American variety. I have chosen to call NMJL / AMJA mah-jongg by the inclusive name "American" as my way of differentiating it from the other 40+ varieties, and still portraying it accurately.
Some purists have said that American mah-jongg is "not mah-jongg," because it is so totally different from all the other types of mah-jongg (primarily in that chows are not used). Some of those purists would therefore undoubtedly object to its inclusion in this list. Much has been learned since the start of the 21st century about other variants that do not include chows, the existence of which weakens the argument of those purists.

WRIGHT-PATTERSON

Uses 144 tiles (some players may add 2 jokers, making a total of 146; probably a table rule).
Flowers are melded instantly when received.
Hold 13 tiles in the hand, go out on 14 tiles.
Many many special hands (70-80 tile combinations).
Count up points based on pongs, kongs, and pairs, then double.
All players earn points (not only the winner).
Books: Wright-Patterson AFB OSC (see FAQ 3, the books FAQ).

WESTERN* (Classical or "Vanilla" Western - British Empire)

Uses 144 or more tiles (jokers are optional and may vary in number).
Flowers are melded instantly when received.
Hold 13 tiles in the hand, go out on 14 tiles.
Many special hands (70-80 tile combinations) which vary slightly from book to book.
Score 20 points for Out, then count up points based on pongs, kongs, and pairs, then double.
All players earn points (not only the winner).
Books: Strauser & Evans, Thompson & Maloney, Whitney, Carkner, Robertson, Pritchard, Glass, Headley & Seeley see FAQ 3, the books FAQ.

* Note: In some of these FAQs I have referred to this style as "Vanilla Western" to differentiate it from other western varieties. Some call this style "American," but this game is played in the U.K., Australia, New Zealand, India, and Italy (as well as other nations that have been or are still are associated with the British Empire). In order to differentiate this game from other so-called American styles (and from European styles if differing from Classical Chinese), I gave it the name "Vanilla" Western. Maybe "Western Classical" is a better name, but it might be even better to call it "British Empire style."

INDIA / MUMBAI

Uses 144 tiles.
Flowers are melded instantly when received.
Hold 13 tiles in the hand, go out on 14 tiles.
Many special hands, similar to Western/British or Wright-Patterson.
Count up points based on pungs, kongs, etc., then double.
All players earn points (not only the winner).
Additional: All players put chips in a kitty at start of each hand. Each round uses different rules (one round permits chicken hands; another round requires special hands; another is a "goulash" requiring all pungs in one suit; fourth round is dealer's choice in which wild tiles may be declared. In some rounds a player can "buy" a discard and take it into the hand. I'd initially thought India/Mumbai mahjong was the same as "vanilla" British/Western mahjong, but learned differently when I visited Mumbai in March 2009. For more details, see column 396 and column 399.

J.P. BABCOCK'S ORIGINAL 1920 RULES*

Uses 136 or 144 tiles.
Flowers, if used, are melded instantly upon receipt.
Hold 13 tiles in the hand, go out on 14 tiles.
Few special hands (tile combinations) -- less than Chinese Classical.
Score 20 points for Out, then count up points based on pongs and pairs, then double. (Kongs and flowers not used in Babcock's original simplified system.)
All players earn points (not only the winner).
Books: Babcock's little red book, "Rules for Mah-Jongg" (out of print, but copies are often sold on eBay -- also see the websites FAQ, FAQ 4b).

* It should be noted that Babcock's rules were "simplified" to make the game more palatable for Western players. Many other 1920s American authors documented the Chinese Classical rules without these simplifications. Babcock was the man who introduced mah-jongg to the West, and many copies of the Little Red Book still circulate today, thus his rule book is listed herein (even though it is long out of print and his simplified rules are rarely used today). (And even though his glib opening statement, "MAH-JONGG is played with a set of 136 pieces of bone or ivory with bamboo backs," often causes sellers to erroneously claim that the set for sale is made of "ivory.")

No flowers or jokers -- nothing but suit tiles.
Hold 13 tiles in the hand, go out on 14 tiles.

Only the winner is paid; discarder pays for all.
Books: none in English. You would have to go to Hunan, or Sichuan (where the variant has also been reported by other correspondents), or Tibet, and/or make the acquaintance of someone from there, to learn the variant. (Thanks to Jo Vandeweghe and Benjamin Boas for the info on Tibetan style, posted September 2006 on the mahjong newsgroup.)

Morten Andersen reported on the newsgroup in November 2007, confirming the above and adding further details on Sichuan style, as played in Chengdu:

Kongs apparently score very well.
Play continues after the first player goes out. And doesn't stop untill three players are mahjong or the wall runs out.
There is a penalty for having all three suit in your hand when the game ends.
Payment is settled between all players according to the value of their hand. (There seem to be few patterns..mostly just full flush and as many kongs as possible seem to score a lot).
Our guide mentioned a local rule from his village to the south which I found very interesting. On his turn a player is allowed to expose his hand if he is waiting, doing so means he can only win on selfdraw but the other players are not allowed to throw any of the tiles he is waiting for which could mean they will end up paying a penalty for having all three suits in their hand when the game ends.
Thanks to Morten for the above. It's interesting that Dragon Chang reports an entirely different way of playing in Sichuan (Szechuan) province, below.

Uses 144 tiles (some players may add 2 jokers, making a total of 146; probably a table rule).
Flowers are melded instantly when received.
Hold 13 tiles in the hand, go out on 14 tiles.
<20 special hands.
Scoring: [not reported]
All players earn points (not only the winner).
No chows. Discards briefly shown, then placed face down in orderly rows like Japanese and MCR. Drawn hands result in a goulash like Western and Indian/Mumbai.
Books: None. Reported by Ian Stanley on the ReachMahjong forum in June, 2009.

TAOIST MAHJONG

Uses 148 tiles (including "gold dragons" which may be represented by blanks or jokers).
Flowers may be melded instantly and replaced from wall, or player may use them to form a pair or larger set.
Hold 13 tiles in the hand, go out on 14 tiles.
No special hands, but there are special sets consisting of 3 different single and paired winds or dragons. There is a fourth "suit" consisting of ones and nines of each set, plus an odd-numbered tile from each set (details poorly understood).
Score 25 points for Out, then count up points for sets.
All players earn points (not only the winner).
Books: none. Information herein thanks to Jeff G on the Mah-Jongg Q&A Bulletin Board, January 2 & 3, 2018. If you have further knowledge of this variant, please contact Tom at Sloperama.com.

DUPLICATE MAHJONG

A form of play similar to usual international competition forms
The walls are prebuilt in a special manner so as to remove the elements of luck; winning is then a matter of skill.
Designed so that mahjong can be considered a mind sport, and so mahjong can qualify as a potential event in the Olympics.
The rules of the Mahjong International League may be read at http://mahjong-mil.org/rules_dup.html .

SIAMESE MAH JONGG ®

Special two-handed rules by Gladys Grad (2015). Its name is a play on the phrase "Siamese twins."
Two players each play two hands, on specially designed two-tiered racks.
Primarily designed with American mah-jongg in mind, the concept can be applied to any variant.

Siamese Mah Jongg ®

http://www.siamesemahjongg.com/

For a comparative analysis of several of the earliest known forms of mahjong, see http://www.sloperama.com/mahjongg/analysis.html.

Also: I have written my own simplified set of mah-jongg rules, in FAQ 10. It's basically Chinese Classical, but without any scoring whatsoever (players simply say "ooh" and "aah" when any difficult or "pretty" pattern exists in the winning hand), and without any significance to the winds or the flower numbers, using my philosophy of harmonious play without gambling. See FAQ 10 for details on these simplified rules; see FAQ 9 for my philosophy of harmonious play.

Again: the names of the various flavors of mah-jongg are not necessarily universally recognized names. Some authorities may call a particular style of mah-jongg by a different name. The names attributed herein represent my own naming convention for the various styles of mah-jongg. Somebody has to make sense out of it all!

* Whitney's "American" game lies somewhere between the game defined by Babcock and the Western game defined by S&E and T&M (primarily in that Whitney lists the common Chinese/Japanese/"American" special hands, and not the full list of Western special hands; Babcock's rules do not include special hands at all).

There is bound to be some difference between the game defined by one author and the same game defined by another author (see P&C vs. Constantino vs. Li vs. Lo vs. Tsui, for example). For the people who use a particular book to determine their table rules, the book defines the rules -- some play groups may agree on different table rules. The main criterion that makes a book "authoritative" is whether or not a reasonable number of people play (or at one time played) according to its rules.

What about Siamese Mah-Jongg?
That's the name given by Gladys Grad to her 2-player subvariant of American/NMJL mah-jongg. It's not from Thailand (Siam), so is not listed among world variants above. You can read about it at SiameseMahJongg.com.
