Welcome to my mah-jong page. Any mah-jong related page with healthy content may link to this page freely.

Due to work commitments, this webpage has not been updated for years. For the latest developments about the Zung Jung mahjong scoring system, please visit the new Zung Jung website.

Here are two links to documents in English on how to play Japanese mah-jong. The first is contributed by Mr. ITO Kazuo and is a comprehensive description of both the Classical Japanese game and the Modern Japanese game. The second is an article written by me some time ago on the Modern Japanese game. (I have originally planned to write a series of articles, but I have never quite got around to write the rest.) Mr. ITO's article would be useful if you need to learn the game and play with human opponents, while mine would be helpful if you already know Hong Kong Old Style mahjong, and are playing some Japanese mahjong video game, and need to find out how the scoring works or why you are sometimes not allowed to go out. These files are text files. My article contains new-JIS encoding; viewing in a fixed-width font with JIS-decoding capability is recommended. (If you don't have JIS-decoding on your system, you'll see gibberish here and there, but the English part of the article is still perfectly understandable.)

This is a link to Mr. Tom Sloper's Mah-jong FAQs. If you are new to mahjong or Usenet mahjong newsgroups, please be sure to read these useful articles. If you have any beginner's question on mah-jong, chances are that you will find the answer in the FAQ.

I have mix-and-matched several Mah-jong scoring systems and put together my house scoring system. If you think Cantonese Old Style lacks variety, Shanghai New Style is too complex, and something must be wrong with Taiwanese style, please check this one out to see whether you like it or not.

The text documents are preferably viewed with a fixed-width font.

If you would like to try Zung Jung with your group, here is a set of scoring aid cards which will make teaching the system very easy. Special thanks to Mr. Gareth J. M. Saunders for preparing these cards in electronic format.

Note: The documents are copyrighted. You are welcome to freely reproduce the documents in whole for playing and distribution, provided that they are properly attributed, to me (i.e. don't change the name of the author to someone else), and that you make explicit the source from which you get the article (namely, this homepage). Also, you must not collect charges for the distribution of the documents. I'll appreciate it if you send me feedback: whether your group likes the system, any changes your group prefer, etc.

Please note that if you have been playing some version of "Western" mahjong and do not know about the true Chinese versions, you'll need to read the following document to learn about true Chinese mahjong before you can make sense of the Zung Jung system. True Chinese mahjong is characterized by 'regular' winning hands such as B-345 C-222 C-789 D-777 D-11. NMJL mahjong is not true Chinese mahjong, while JMJA mahjong is considered an (adequately) close variant of Chinese mahjong.

Mahjong, being a "parlour game", can be studied mathematically under the sciences of game theory, probability theory, and combinatorics. Here are some articles which take a combinatoric look at various elements in the game. Some mathematical background in basic combinatorics is expected of the reader.

And here are a couple of articles about the historical development of mahjong. Many facts about the early forms of mahjong are unknown to most players!

Four Winds is an excellent shareware mahjong game for Windows 95. It allows you to play various "Classical" versions of mahjong, among others. Have you ever wondered what the game of mah-jong was like, before it became Hong Kong Old Style or Modern Japanese style? Here is the link to the official Four Winds website:

Hong Kong Mahjong is a mahjong software with excellent graphics and music. Besides Hong Kong Old Style rules, a version which supports Zung Jung rules is also available.

Following are some articles in the Japanese language, composed or translated by Mr. ITO Kazuo:


Many thanks to Mr. ITO Kazuo for these articles!
