The following rules are based on the game rules published by the British Mahjong Association

Game Play

British Version of MahJong is played in the same way as the Chinese game with the following changes.

Each player may declare only one Chow per round.
In addition to the 10 special hands shown for the Chinese game, the following special hands are also legitimate.

Playing with Flowers and Seasons

Use of the Flower and Season tiles is optional. Flowers and Seasons are rarely used by the Chinese or expert players because they increase the element of luck and decrease the element of skill.

The Kong Box

During the preparation stage, an additional step occurs after the last preparatory action is to create the "Kong Box", sometimes known as the "Dead Wall". Starting from the break in the wall, and this time counting anti-clockwise, the first six piles of tiles, making a total of fourteen tiles including the loose tiles, are separated slightly from the remainder of the wall. These tiles are the Kong Box and are used exclusively to provide replacements for Flower, Season and Kong declarations.

Building the Wall

The wall built in front each player should be 18 tiles long, and consist of 36 tiles.

During the game

If a Flower or a Season tile is dealt to a player, then that player immediately declares this and replaces it from the Kong Box.

Scoring

Each Flower or Season counts 4 points.

The following also double the basic score for any player:

Holding player's own Flower (1=E,2=S,3=W,4=N)	Double
Holding player's own Season (1=E,2=S,3=W,4=N)	Double
Holding complete set of Flowers	Double twice
Holding complete set of Seasons	Double twice
