Appendix VIII - Mahjong - International Scoring
Introduction
The Qualifying Events at SIGA uses the scoring system used in World Series of Mahjong, which
was developed for international Mahjong competitions, with the goals of: rules simplicity and
ease of learning, international fairness, and game playability (competition of skill).
Basic Rules
1. Only the winning hand is scored. The winning player collects points, corresponding to the
value of the hand, from the other three players according to the “payoff scheme”.
2. The 44 “patterns” are listed below. Each pattern specifies a certain condition; for fulfilling
the specified condition, the winning hand scores the specified point value. There are no
“basic points” added for winning the hand itself; a hand scores only for the patterns it
contains.
3. The patterns are organized into categories and series. In the numbering, the first number
indicates the category, and the second number indicates the series (within that category). For
example, “3.3” indicates the “Winds” series in the “Honor Tiles” category.
4. Additive Rule: When the winning hand fulfills the conditions for multiple patterns, the value
of the hand is generally the sum of the values of the relevant patterns. (The multiplicative
“Faan” system is not used.) You can count all patterns contained in the hand (even if one of
them constitutes a necessary condition for another), provided that they belong to different
series. You cannot count multiple patterns from the same series, nor can you count the same
pattern more than once. (“3.1 Value Honor” is an exception: you can add 10 points for each
set of value honors in your hand.) As an example, a hand with “Four Concealed Triplets” is
always also a “Concealed Hand” and an “All Triplets” hand, so such hand always scores at
least 125+5+30=160 points.
5. No Minimum Requirement: Under the new tournament format for this year’s event, the
benefits (and the damages received by the opponents) of the “chicken hand” is greatly
reduced. Hence the prohibition on the chicken hand is now abolished; one may win with a
regular hand even if it contains no patterns. A “chicken hand” scores 1 point..
6. Maximum Limit: There is a “limit” of 320 points. If the hand contains multiple patterns of
which values add up to 320 or more, the hand scores 320 points (called a “Compound Limit
Hand”). But if the hand contains a pattern which has a listed value of 320 or more (called a
“Listed Limit Hand”), it scores the single highest-valued pattern in the hand. (It scores for
one single pattern only.)
7. For some basic rules on winning and scoring, please see the section on “Scoring the Winning
Hand” in the “Mahjong Rules” chapter, in particular the rule on “Freedom of Count”.
Appendix VIII - Mahjong - International Scoring
Payoff Scheme
1. Fixed Income Principle: The total income of the winning player is determined solely by the
total value of the patterns in his hand: the income is always 3 times the pattern value. It will
not fluctuate just because the player luckily self-draws. The payoff scheme here specifies
how this payment should be split among the three other players.
2. Everybody pays for self-draw: When the winner self-draws, no one is “responsible”. When
no one is responsible, the payment is split equally among the three other players: each player
pays the winner 1 time the total pattern value of his hand.
3. Discarder pays for big hands: When the winner wins on discard, in general the discarder is
“responsible” (exception explained below). 25 points is taken to be the standard score value;
for small hands of 25 points or less, the three players split the payment equally (regardless of
who is responsible), and each player pays the winner 1 time the total hand value. For a big
hand of over 25 points, each player first pays the winner 25 points, and then the responsible
player pays the rest. For example, if the winning hand is 70 points, the two non-responsible
players each pay 25 points, and the responsible player pays the remaining 160 points. The
winner gets in total 210 points, which is exactly 3 times 70 points.
4. Rule of Same-Turn Immunity: When the winner wins on discard, if in the same turn
(starting from and including the winner’s previous discarded tile, until before the win)
another player has just discarded the same tile as the winning tile, then the discarder will not
be “responsible” for having followed with the same discard. The player who first discarded
the winning tile in the same turn (after the winner’s previous discard) will be considered
responsible. But if the winner has just discarded the winning tile, then no one will be
considered responsible (and the payment split equally among the three players just like a selfdraw win).

make a concealed triplet if you win on self-draw, and an exposed triplet if you win on discard.

10.0 Irregular Hands
Irregular Hands are hands that do not consist of 4 sets and a pair. An irregular hand does not
count for “Concealed Hand”.
Thirteen Terminals 160 Among the 13 types of terminals and honors, the hand contains one
(十三么九)
pair of one type, and one tile each of the other 12 types.
Seven Pairs
30 The hand consists of seven pairs.
(七對子)
Example:
,
,
,
,
,
,
Four identical tiles can count as two pairs as long as kong is not
declared.
A Seven Pairs hand cannot count those patterns which specifically
require triplets, kong, or sequences. But it can count other patterns
which do not have such requirements.
