Pinfu -why also called "No Point" 01

A hand composed of sequence units (run) is called pinfu (peace).
Pinfu is also known as "no point," since this hand has no extra base points (mini-point) or "fu."

Basically the concept of evaluating hand is simple: the harder to complete, the higher the score will become.

Your hand will be counted as follows:

0. You will unconditionally earn 20 point.
1a. If your hand is concealed and going out with other player's discard, you will earn another 10 point.

1b. If your hand is concealed and going out with your self-drawn tile, you will earn 2 point and
     1 yaku, Tsumo(official name: menzenchinmohou 門前清摸和.)
     Pinfu is the exception: if you go out pinfu self drawn, at least you secure tsumo as well as pinfu
     without gaining 2 point : see Pinfu 02
1c. If your hand is partly revealed and going out with your self-drawn tile, you will earn 2 point.

2. If your hand contains a triplet or a four, you will earn extra point, from 2 to 32 according to the type.
3. If your last waiting component requires only one sort of tile, you will earn 2 point.
4. If your pair (eyes) is dragons, round wind or your own wind, you will earn 2 point.

Pinfu has only 0. and 1a...30 points. Therefore it is also called No Points.
Pinfu is 1 fan hand, one double, meaning 30 * 2 = 60 points.
In those days even if some player mistakenly discards a winning tile, each player except the dealer pays 60.
The dealer pays double: 120.

Later the rule has changed in Japan...the one who discards the winning tile pays all.
In this case, the loser pays 60 * 4 = 240.

In less than 50 years, the score has become inflated...4 times.
Today pinfu counts 240 * 4 = 960 rounded up to 1000.




If your pinfu contains no honor or terminal, it is also tan-yao ("tanpin")
Tan-yao is 1 fan, one double.
The score will be 960 * 2 = 1920 rounded up to 2000.

If your pinfu contains "mixed triple chow," three similar sequences (sansyoku)
the score will be 960 * 2 * 2 = 3840 rounded up to nearest hundred...3900.
Sansyoku is 2 fan, two doubles.

If your pinfu is tan-yao and contains sansyoku,
your score will be 960 * 2 * 2 * 2 = 7680 rounded up to 7700.

Please memorize the pinfu score as 1000-2000-3900-7700.
Do not calculate as (20+10)*4*2*4.
If you are a dealer, the score will be 1500-2900-5800-11600.
