Riichi yaku/scoring quick reference.

[villadelfia]

I have made a quick reference sheet for the yaku and scoring, in this case the yaku as used in Mahjong Fight Club.

The italic bolded yaku need to be concealed.

Edit: Made an oops, open tanyao is allowed in MFC, pdf has been updated to reflect that change.
Edit2: Made some more fixes.

[Robert]

Is open tan\'yao really prohibited in MFC?

[Poochy]

Nope, MFC rules have kuitan ari (open tanyao allowed).

[villadelfia]

Is there a scoring difference between open and closed tanyao in mfc?

Never mind that, I fixed it, please tell me if there are any other mistakes.

There is a space missing in Sousuushii, it says \"... windsand...\"

Also you should remove the \"... and a pair\" from Toitoi and Ryanpeikou. It\'s unneeded and inconsistent (you don\'t have it on Suu kantsu for example).

Haitei Raoyue is only going out on last selfdraw from the wall, if it\'s the last discard it\'s called houtei raoyui, minor nitpick but still :).

Done and done.

I know, but the page was full, and they\'re basically the same thing.

On a completely unrelated note: toitoi is the most awesome name for anything ever.

I assume this is copied from the EMA guide since the layout is very similar? You have the same confusing translation where Iihanyaku is given as One Yaku when it should be One-Han Yaku (etc).

Also the column heading on the limits table says Fu where it should be Han.

On the same table, a more complete defintion of Mangan would include 4 Han with 40+ Fu and 3 Han with 70+ Fu.

Isn´t Dai Sharin usually limited to the Dots/Pinzu suit?

(also if anyone knows if the \"correct\" reading is \"big wheel\" or \"big wheels\" then I´d love to know! B))

I didn\'t like the original, so I made my own in a similar but better lay-out. I also cross-referenced the MFC Yaku list using wikipedia. Anyway, fixed.

Also the column heading on the limits table says Fu where it should be Han.

Oops, missed that. Fixed.

Ha, I didn\'t even know that. Thanks. Fixed.

I don\'t know whether this is the case in MFC, if anyone here could confirm/deny it, I\'d love that.
I\'m leaving that as it is for now.

[Barticle]

Specifically Mangan is defined as a limit of 2000 base points.

Since base points are calculated with Fu x ( 2 ^ ( 2 + Han ) ) there are three ways this can happen.

With 3 Han and 70 Fu you have:

70 ... x2 x2 ... x2 x2 x2 = 2240

With 4 Han and 40 Fu you have:

40 ... x2 x2 ... x2 x2 x2 x2 = 2560

And with 5 Han you will always get Mangan because even the smallest possible amount of Fu will give you over 2000:

20 ... x2 x2 ... x2 x2 x2 x2 x2 = 2560

If your game has the same stats pages as the PS3 version then you should have a breakdown of how many Han you got in each hand and you´ll notice that 4 Han is not listed. Instead 4 Han hands are counted under Mangan because you either get Mangan points or (if less than 40 Fu) only slightly less.

I don\'t know whether this is the case in MFC, if anyone here could confirm/deny it, I\'d love that.

I checked the manual at home last night.

It says "pinzu no 2-8 o subete toitsu de soroeru yaku" which - loosely translated - means "2-8 of Dots, all pairs, to make the yaku".

Oh, in that case the normal tables already mentioned it, just the limit hands table didn\'t.

And the issue with Dai Sharin has been fixed.

[Barticle]

Yeah, of course it´s not incorrect to say that you get Mangan on a five-Han hand but it´s not a complete description. The score tables do show the limit in effect - they just don´t draw attention to it.

The new footnote should say 40+ for 4 Han by the way.

Oh, and I assume you chose to omit Nagashi Mangan?

Yes, I don\'t feel it fits in the table since I wouldn\'t really consider it a yaku. I consider it a special rule, like being able to draw the game when the same wind is discarded as the first 4 tiles. (On that note, MFC once gave me the option to draw the game on my first turn, but the discarded tiles were not even winds, I\'ve no clue why that happened. Anyone care to enlighten me?)

I might put it in the footnote for mangan, but that might look weird.

If you have any ideas where I could put it, please say.

Thanks for all the help everyone, I think the cheatsheet is now without error and quite usable for newer players and older players too.

[Barticle]

I think it counts as yaku, although clearly it´s not a normal one. :) It doesn´t cause the draw - it lets you score some points after a hand has ended in a draw.

(On that note, MFC once gave me the option to draw the game on my first turn, but the discarded tiles were not even winds, I\'ve no clue why that happened. Anyone care to enlighten me?)

Sure, it´s one of the other types of abortive draw - it´s called Kyuu Shu Kyuu Hai (nine types, nine tiles).

If, on your first turn, you have nine or more different terminals and honours then you can declare a draw and have the tiles dealt again.

I like to take it as a helpful indicator that I have a good chance at making Kokushi Musou. Refuse the draw and start dropping those simples! :laugh:

It is a fourth way to make a Mangan so that would be a good place to put it if you don´t want to list it with the yaku.

Since only 784 out of 34555325440392000 possible 14 tile combinations (136!/(14!*122!)) qualify for Kokushi Musou.
Even with 9 terminals/honours the chances would be slim, though I can\'t calculate how slim exactly.

Ok, it has been added to the pdf, note I only mention that it is known as Nagashi Mangan, I couldn\'t find a way to rephrase it in such a way to include \"it is worth a Mangan\" and still fit on the page.

[Barticle]

Say you start with exactly nine different T&H you only need to self-draw four of the five tiles you require then you can either draw or ron the fifth one to win. You have typically 17 or 18 turns to do this if no-one else goes out first.

Actually, assuming you already have the pair (I always seem to get at least one or two pairs in a hand like this) then you only need four discrete tiles to complete.

Back before making my first Kokushi I was very keen to get one and used to try starting with eight T&H. Pretty sure I got it once from eight, and it´s quite achievable with nine, although obviously you still need a little luck.
