missed win and final points

[Murena]

Hello,

I\'ve been knowing the game for two years now, but sometimes still there is something I\'ve doubts on^^

One rule is the missed win, that is if I pass the chance to win on a discard I can\'t win on the same go-around by ron. (Is that right?)

Lately I watched Akagi again and the following happened:
akagi was dealer. North discarded the winning tile but akagi didn\'t claim. Next, South discarded the tile and Akagi rons.
Maybe there wasn\'t missed win rule on akagi\'s time, or the go-round is meant to start on east? (So north discard was of the previous go-around).
Could you help me on this?

Then, how final points are calculated? I mean the points like -33 +5 -20 and the like.

Thanks

I\'m no where near the point where I can start giving advice, so don\'t quote me on this.

For the first question: In Saki, the same thing happened. Akeda (the character) was thinking what to drop and noticed that the person left of her already dropped an east (I don\'t exactly remember what tile it was, but it doesn\'t matter), so it should be safe. Then she got ronned for a baiman (the person ronning was trying to directly target her), so I don\'t know. Though, if I remember correctly, Koromo switched her wait or something, it\'s quite blurry! Sorry.

For your second question, the calculation that I remember is.

(CurrentPoints - Initial Point)/1000 = +- score. You do the Uma before this. +20 to the winner!

The missed win rule is like this = when you have riichi, if you don\'t declare, you cannot win from anyone, except by drawing the tile yourself

without riichi, your furiten disappears after your own turn, so if player to your left discards your winning tile and you don\'t declare it, you can win again after your own turn has passed.

Hopefully I made my text understandable :P

Then what are the doing in Saki and Akagi? ^^

@WorTeX
You mean if I\'ve riichi if i don\'t declare a ron, I can\'t win by ron forever in that hand, but if i don\'t riichi i can win after one turn passed? Didn\'t know this difference.

You mean if I\'ve riichi if i don\'t declare a ron, I can\'t win by ron forever in that hand, but if i don\'t riichi i can win after one turn passed?

Yes.
Two more things:
1) A turn is "passed" when you draw a tile or when someone claim a discard.
Exemple: You are East, waiting for a 2pin. South discard a 2pin, and you let pass --you become furiten--. West discard a 6wan. North claim that 6wan for a chii or a pon --you are no longer furiten--. North discard a 2 pin, you can win on it.
2) Tiles you have discarded yourself makes you furiten until you change your wait and don\'t wait on them anymore.


For what happend in Akagi (or Saki), I can\'t help you without the exact reference (I mean the episode or volume+pages number).

(CurrentPoints - Initial Point)/1000 = +- score. You do the Uma before this. +20 to the winner!

The final Oka bonus depends on what the starting score is.

Commonly players buy into a game with 30000 (initial points) but start the game with 25000 which leaves 5000 each spare, making the Oka 20000 points (or +20 after you´ve divided by 1000).

If they start with 27000 pts then the Oka is 12000 (4 times 3000) or if they play with 30000 then there´s no Oka.

Murena, you´ll notice that the effect of this calculation is to make the four final scores (the -33 etc) add up to zero.

...oh and welcome to the forum. :)

Still is not very clear to me. For example i had this score on tenhou yesterday

1) 64600 +74
2) 18800 -1
3) 10500 -29
4) 6100 -44

How exactly is calculated and rounded?

As a guess, is this is a cumulative total?

[Murena]

it\'s the final score from a normal east-south round.

Tenhou recently change their uma to 20/10 so i was suprised at first when i saw this score. Because Uma is the most tricky part when counting point. Tom made very nice explanation how to count those point at: http://sloperama.com/mjfaq/yaku/yaku.htm (bottom of the page)

Let my explain:
64,600 = you round up (tenhou round down here, dont know why), so you get 65,000 (64,000). Goal is 30,000 so you have to subtract it. you get 35,000 (34,000) over the goal. To that the first place get 20,000 for wining. Now you divide by 1000 (to get rid of those 000), so you have 55 (54) and to this you ad uma (in this case 20), so you get 75 (74) like you wrote.

second place: 18,800 = 19,000; 19,000-30,000= -11,000
-11 +uma(10) = -1

third place:
10,500 = 11,000 (Imho sould be 10,000 but tenhou rounds different, dunno why); 11,000- 30,000 = -19,000
-19 +uma (-10) = -29

fourth place:
6,100 = 6,000; 6,000 - 30,000 = -24,000
-24 +uma(-20) = -44

So it all as you wrote (expect this rounding up and down, i wonder why there is difference).
Also you can get rid of thos 000 earlier.

Okay, got it figured out. There are two payments here:
-5 to all, + 20 to winner, and +20 to first, +10 to second, -10 to third, -20 to fourth.

Code: Select all

             rounded  init  win   uma
               pts    pts   pts
1) 64600 +74 =   64  - 30 + 20  +  20
2) 18800 -1  =   19  - 30 +  0  +  10
3) 10500 -29 =   11  - 30 +  0  -  10
4) 6100 -44  =    6  - 30 +  0  -  20

First place got rounded down to ensure that the final scores all add to zero. (It\'s the Law of Conservation of Money!)
(74 - 1 - 29 - 44 = 0)

Okay, got it figured out. There are two oka payments here:
-5 to all, + 20 to winner, and +20 to first, +10 to second, -10 to third, -20 to fourth.

There is one oka 20,000, and there is uma +20/+10/-10/-20.

First place got rounded down to ensure that the final scores all add to zero. (74 - 1 - 29 - 44 = 0)

That makes sens, but souldnt it be accurate with normal rounding from the beggining?

[Murena]

Thanks for reply, i understood now.

For rounding I knew that the winning player is rounded last to keep sum to 0.
