Four Winds Rule Collection – Japanese Classical

5. Scoring

5.1 Displaying the hands

The Japanese rules allow payments to the winner only: there are no payments between the losers. Accordingly, only the winner must display his hand after a deal is over.

The winner is responsible of arranging his hand in a way that makes it clear which sets it is composed of, melded sets placed above the sets in the hand. The winner should mark the winning tile by placing it at right angles to the others, and should he wish to claim any score for special ways of going out (e.g., for Out on a one-chance Chow, Out on a pair, etc.), he must show the tile he has drawn from the Wall before adding it to his concealed hand.

If a concealed portion of the hand can be arranged in more than one way, a player is free to arrange it in a way that results in the best scores. E.g., if a player is calling with Bamboo 2-2-3-4 and the winning tile is Bamboo 2 (either self-drawn or discard), a player is free to arrange his hand so that the winning tile is considered to complete the pair of Bamboo 2-2, rather than the Chow 2-3-4 (both arrangements are possible but the previous one pays two extra points).

5.2 Calculating the value of hands

In Japanese classical rules the available scoring units are points and doubles. Accordingly the scoring is performed by first summing up the patterns that earn point values and then applying doubles.

5.2.1 Basic points to the winner

The winner receives the following basic points for the completed sets.

e.g. 1-2 or 8-9 or n-?-n+1 (middle tile missing), as opposed to going out on a Chow that can be completed on both sides.		 2 pts
Out on a pair (ch. tan chao machi, jap. danki) 2 pts
5.2.3 Doubles for the winner

 No-points hand (Ch. pin fuu, Jap. pin fu)
A hand that does not include any other patterns that score in point units than Winning and Concealed hand. (But the hand can contain patterns that earn it doubles).
Note: In practice requires that the hand consists of four Chows and the winning tile is a discard and used for a multi-chance Chow and that the pair is a non-scoring one.
Optional: Sometimes players agree that a No-points hand may go out one a one-chance Chow (worth 2 points), or a pair (worth 2 points), or be self-drawn (also worth 2 points), and still score 1 double for No-points, but when this is allowed, extra points for these special ways of going out are not paid, either.		 1 dbl

Out on a supplement tile (ch., jap. rin shan kai ho) 1 dbl
Out by robbing a Kong (ch., jap. chan kan)
Note: Robbing a Kong is considered going out on a claimed tile (and the player declaring the Kong is considered a discarder). Accordingly, a Kong robber can get extra points for Out on the last discard. 		1 dbl

5.3 Calculating the total score

When the basic points and doubles have been calculated, the total score for the hand can be determined. E.g., let us assume that the winner is North on the South round and that he goes out on the following hand (claiming the East wind from East):

Character 5Character 5Character 5 Red DragonRed DragonRed DragonRed Dragon

Bamboo 2Bamboo 2Bamboo 2  Dot 1Dot 1Dot 1 East      East

He gets the following basic points:

4 pts Concealed Pung of Simples (Bamboo 2)
8 pts Concealed Pung of Terminals (Dot 1)
2 pts Melded Pung of Simples (Character 5)
16 pts Melded Kong of Dragons (Red Dragons)
20 pts Winning
2 pts Out on a pair (East wind)
52 pts Total points

The basic points are rounded off to nearest ten before applying doubles, so the total points are 50.

The winner gets the following doubles for his hand:

1 dbl Kong of Dragons
1 dbl Pung hand
200 pts Final score (50 pts doubled twice)
5.4 Limit

If a player's total score exceeds 500 points, it will be cut down to 500 points. Note that this is done before applying payment doubles. 

5.5 Scoring accessories

A sheet of paper and a pencil is sufficient for keeping the scores, but normally Mah Jong sets come with counters or chips, valued at 500 points (marked either with 6 red and 6 black dots or more commonly, with 5 red dots), 100 points (marked either with 2 red dots, or more commonly with 1 red dot), 10 points (marked either with 8 black dots or more commonly, with 10 black dots) and 2 points (marked either with 1 red and 3 black dots or more commonly, with 2 black dots). If scoring accessories are used, players naturally exchange them at the time of payments.
