Still learning, and a bit confused.

Post by imagoth2004 » Sat Jan 16, 2010 2:24 am

I\'ve played chinese mahjong a few times in the past, and my friend has been teaching me Riichi Mahjong. During one of our games I was North, and I ended up going out on a discard by West. I don\'t remember what I had, but he told me it was worth the Limit of Haneman, and worth 12000.

Earlier today I was going through trying to find rules, and hands and found this neat little wiki site.

But down in the limit hand table I don\'t understand how I ended up with 12000 if it only shows two 6,000, and one 3,000. Can anyone explain how those tables work? :unsure:

Yes. Someone can. Is that really what you\'re asking? For somebody to explain all about how the tables work? Or are you looking for a clearer understanding of the hand you won on?

BTW, 6000 + 3000 + 3000 = 12000

Dealer always pays/receives the higher of the two amounts. You were non-dealer, so the dealer and the two other players paid you and you received (apparently) 6000 + 3000 + 3000 = 12000

Well I\'m trying to understand both, but now that I know how it worked for my hand, how do I read the tables?

Some other folks recently posted some links (in other threads) and they\'ll probably answer you. In the meantime, maybe this will help (jump on down to the tables):
http://www.sloperama.com/mjfaq/yaku/yaku.htm
You have to know if you\'re a dealer (oya) or a non-dealer (ko), and whether you won the hand by self-pick or by someone\'s discard (and if by discard, was it a dealer or a non-dealer).

For non-limit hands:
- If you are East (dealer) and win by tsumo (self-pick):
Take the value corresponding to your mini-points (fu) and fan.
Each other players pay you this value.
For example, 30 fu 2 fan is 1000, so each opponent give you 1000. You get 3x1000 = 3000.

- If you are East and win by ron (discard):
The table says 30 fu 2 fan is 2900.
Only the player who throw your winning tile pay, others pay nothing.
So you get 1x2900 + 2x0 = 2900.

- If you are NOT East, win by tsumo:
The tricky table gives two values: 500 and 1000.
East pays you the upper value. The two other players pays the lower value.
You get 1x1000 + 2x500 = 2000.

- If you are NOT East, win by ron:
The table shows only one value again: 2000.
The discarder pays this, other pay nothing.
So you get 1x2000 + 2x0 = 2000.


For limit hands:
- If you are East, tsumo:
Take the value in the \"East\" column.
Each players pay you this value.
For a mangan, you get 3x4000 = 12000.

- If you are East, ron:
Take the same value in the same \"East\" column. The discarder pays you 3 times this value (other pay nothing).
You get 1x(3x4000) + 2x0 = 12000.

- NOT East, tsumo:
East player pays you the value in the \"Dealer\" column, others pay the value in the \"Others\" column.
You get 1x4000 + 2x2000 = 8000.

- NOT East, ron:
The discarder pays the sum of the value in the \"Dealer\" column and twice the value in the \"Others\" column.
As usual, others pay nothing.
You get 1x(4000+2x2000) + 2x0 = 8000.

The basic (but a bit poorly explained) scoring works like this: You take the amount of yaku (han) and add two, then you double that by the amount of minipoints (up to max a mangan). What that means is basically: minipoints * 2^(yaku+2) = score

This is just so you understand the method, not nessecary to use it in real game, tables works fine.

When learning the limit hands I recommend you learn all their names and how many yaku for each. Then for the score all you need to remember is this:

Mangan: 2000
Haneman: 3000
Baiman: 4000
Sanbaiman: 6000
Yakuman: 8000

You need to remember that you should get paid the same amount, doesn\'t matter if you win on ron or tsumo.
If you\'re non-dealer on tsumo that means that every one should pay you the amount posted above, except east who pays double (which means you get the table score*4). If you win on discard you should get *4 from the person who discarded the tile.
In case you\'re the dealer you shuold first double the score from the table above. If you win on tsumo that amount is payed by all 3 players, if you win on ron that amount*3 is payed by the discarder.

Non-dealer: table score * 4 (1:2)
Dealer: table score * 2 * 3 (1:1)
