# American mahjong

American mahjong, also spelled mah jongg, is a variant of the Chinese game mahjong. American mahjong utilizes racks to hold each player's tiles, jokers, and "Hands and Rules" score cards. It has several distinct gameplay mechanics such as "The Charleston", which is a set of required passes, and optional passing of the tiles.
American mahjong is played with four players using mah jongg tiles. The goal of the game is to be the first, by picking and discarding, to match one's tiles to a specific hand from the annually distributed scorecard published by the National Mah Jongg League (NMJL) and American Mah-Jongg Association (AMJA). Scoring is done by matching the points assigned to each pre-determined hand on the annually distributed NMJL card & AMJA card.

## History

Joseph Park Babcock, a representative of the Standard Oil Company in Shanghai, was importing mahjong sets to the United States in great numbers by 1923. To increase interest in the game in the United States, he wrote and published new rules that became the American standard. When the National Mah Jongg League, Inc. published a volume of "Official American Rules" in 1935, the American style further morphed into a very distinct form.
American mah jongg tournament standards and rules were established in 1986, when the National Mah Jongg League and Mah Jongg Madness jointly conducted their first annual Mah Jongg Tournament at Sea. This tradition of championship tournaments at sea continued for over 34 years. Now there are American mah jongg tournaments conducted throughout the United States, and consist of players from America and Canada. Mah Jongg Madness conducts more than a dozen tournaments a year and an annual NMJL cruise culminates in the National Mah Jongg Convention in Las Vegas every March.
Tournaments are now played according to the Standardized National Mah Jongg Tournament Rules, which were codified and published in 2005. In 2011, Mah Jongg Master Points (MJMP) were established to post an individual's tournament scores. The MJMP website formulates the scores (awarding bonus points to the top 10 winners of an event), and ranking the individual players. There are 10 ranks for players, based on the accumulation of these points.

## Using tiles

The total number of mahjong tiles in the American mahjong is 152, as shown below. American Mahjong sets are notably different from Chinese Mahjong sets, and can be identified by the usage of several additional tiles, Arabic numerals, and English words.

### Dots

From one dot to nine dots, four tiles of each type, 36 tiles in total. The dots represent Chinese coins, such as the Kaiyuan Tongbao.
For the convenience of American players, Arabic numbers are usually written on the tiles, stating how many dots it is.

### Bamboos (bams)

From one bamboo to nine bamboo, four tiles of each type, 36 tiles in total.
The one bamboo also known as the bird.
For the convenience of American players, Arabic numbers are usually written on the tiles, stating how many bamboos it is.

### Characters (craks)

From one crak to nine craks, four tiles of each type, 36 tiles in total. The top Chinese characters represent the numbers 1 to 9 and the bottom character is the numerical unit of 10,000.
For the convenience of American players, Arabic numbers are usually written on the tiles, stating how many craks it is.

### Winds

The four types of winds are: East, South, West and North, four tiles of each type, 16 tiles in total.
For the convenience of American players, letters "E" (for East), "S" (for South), "W" (for West) and "N" (for North) are usually written on the tiles.

### Dragons

The three types of dragons are: Red dragon, Green dragon, and White dragon (also known as soap), four tiles of each type, 12 tiles in total. In American Mah Johngg sets, the more traditional red "中" (“middle") and green "發" ("wealth") characters are sometime replaced with images of a red and green dragon, respectively, avoiding the use of Chinese characters.
or
For the convenience of American players, English words "Red", "Green" and "White" are usually written on the tiles, stating which dragon it is. Alternatively, some sets will print letter "C" (for "中" in Cantonese Romanisation) on the red dragon, "F" (for "發" in Cantonese Romanisation) on the green dragon, and "P" or "B" (for "白" in Cantonese Romanisation) on the white dragon.

### Flowers

In the demonstration of NMJL, the two groups of flowers are "Spring (春), Summer (夏), Autumn (秋), Winter (冬)" and "Fortunate (福), Luxurious (祿), Longevity (壽), Noble (貴)".
However, the two groups of normal flowers commonly found in mahjong tiles, i.e. "Spring, Summer, Autumn, Winter" and "Plum blossom (梅), Orchid (蘭), Chrysanthemum (菊), Bamboo (竹)" can also be used.
Each flower associated with an Arabic number and a specific direction, as below:
Flowers :
| No | Name | Character | Direction |
| 1 | Plum blossom | 梅 | East |
| 2 | Orchid | 蘭 | South |
| 3 | Chrysanthemum | 菊 | West |
| 4 | Bamboo | 竹 | North |
Seasons :
| No | Name | Character | Direction |
| 1 | Spring | 春 | East |
| 2 | Summer | 夏 | South |

For the convenience of American players, English words "Spring", "Summer", "Autumn", "Winter" and "Plum.B", "Orchid", "Chrys", "Bamboo" are usually written on the tiles, stating which flower it is. Besides, some will say Arabic numbers 1 to 4.

### Jokers

## Learning to play

The NMJL publishes an official instruction book every few years called Mah Jongg Made Easy. The most recent version was published in 2020. The book, a Visual Companion Guide for American Mah Jongg (VCG) by Dara Collins and Donna Kassman contains graphics and explanations to learn to play, improve strategy, and incorporate Best Practices. The VCG is based on the most up-to-date official rules found in Mah Jongg Made Easy, as well as includes updated rules from annual bulletins, letters to the League, and calls to the League and is available on Amazon.

## Rules

The hands are usually placed on the rack, and the tiles called and shown must be placed on top of the rack.

### Compositions of tiles

The compositions of tiles are: single, pair, pung, kong, quint, and sextet.
There is no chow. At the same time, the traditional composition winning hands (four compositions and one pair) is not present in the American mahjong.

### Joker tiles

Joker tiles cannot be passed to the other players during Charleston (exchanging tiles). When 3 Joker tiles goes together, they can be a composition.

## Game overview

The players roll dice to determine East. The highest roll is designated as East. Each player then stacks a row of 19 tiles, two tiles high in front of them (for a total of 38 tiles). Then the East player will decide the opening position with two dice, and each person will take 13 tiles in hand (14 tiles for the East player). After the tiles in hand have been sorted, if the East player has a completed hand, called the Heavenly Hand, he/she wins instantly. Otherwise, the Charleston -- exchange 3 tiles with other players -- will be conducted. It takes three stages:
* Each player passes three unwanted tiles to his/her right, and receives three tiles from the player on the left.
* Each player passes three unwanted tiles to the player across, and receives three tiles from the player across.
* Each player passes three unwanted tiles to the player on his/her left, and receives three tiles from the player on the right.
This is one Charleston. A second Charleston takes place unless any player chooses to stop the passing. The second Charleston is done in reverse order: left, across, right.
On the last pass of each Charleston (first left, second right), a blind pass is permitted. This means a player can take one, two, or three tiles that were passed to him/her and, without looking at the tile(s), can pass it/them instead of tiles from his/her hand. Each pass still includes three tiles.
Following the Charleston passing, an optional pass take place. Players have the option of passing zero, one, two or three tiles to the player across from him/her. The two players agree on the number of tiles to be passed.
The game begins with East discarding a tile, and proceeds until all the tiles are taken from the walls of tiles or a player declares Mahjongg after completing his/her hand.

## Scoring method

NMJL publishes an official rulebook every year, and the winning hands will change every year.
The minimum score for a winning hand is 25 points. In the case of calling Mahjong (winning), the player who discarding a tile from which another player calls mahjong must pay twice the number of points, while the other player pays only the number of points. In a self-draw, the other three players pay twice as the points.
