Reach Mahjong Rules

Ch. 3: The Goal

The Goal
Hands Down Each hand in play consists of 13 tiles
Hand in Play
And a winning hand contains 14 tiles.
Winning Hand
Players must make 4 sets of 3 and one set of 2. These sets consist of Groups and Runs
Groups A Group is a set of tiles that are identical. Groups can consist of 3 or 4 tiles. 3 of a kind Groups are often referred to as 'Pungs', we will borrow the poker term and call them 'Trips' (short for triples).
Trips
You may also use 4 of a kind groups are often referred to as 'Kongs'. Again, we like to use English terms, so we will call them 'Quads'.
Quads
In Reach Mahjong, a Group of 3 is only referred to as a Pung if the third tile is taken from someone else's discard, so we will call them Trips. Also, Pung is not an English word, so when we refer to stealing the third tile in a Trip, we will use the English translation of 'Bump'. There is only one word for Quads, so we will call them concealed or open Quads, depending on if the 4th tile was stolen or drawn. Since there are 4 of each type of tile, any tile can become part of a Group. Make sure your Groups contain IDENTICAL tiles!!! No mixing of suits, winds or dragons.
Group No-No's
Runs A Run consists of 3 tiles that are sequential in number. For this reason only Bamboos, Grands and Dots can become part of Straights.
Runs
A Straight can only contain 3 tiles and all tiles must be the same suit. 1 and 9 cannot be used together
Run No-No's
So there are only 7 possible combinations for Runs in each suit.
All possible Bam Runs
A Run of 6 becomes 2 separate Runs
Run of 6
A run of 9 becomes 3 separate Runs.
Run of 9
Pairs Each hand requires one Pair called the 'Head' or the 'Eyes'. The Head must consist of 2 identical tiles. Any tile may become part of the Head unless specific Hand Point rules specify differently.
Pairs
Since a hand in play only has 13 tiles, a hand that is Ready (one-away) will be missing a tile in one of its sets.
Ready Hand
A finished hand will contain 4 sets of three (Groups or Runs) and 1 pair.
Finished Hand
Now that you know where you're going, go to Ch.4 The Play to find out how to get there!!
