I really enjoyed the puzzles, behind most of which I recognize Vitaly's work about MCR and waits analysis he studied years ago.

It is difficult to judge the difficulty of problems, but some did take me some time to solve.

I especially enjoyed the '32nd of December' and its fourth question.

Thanks to Vitaly for the problems, to Martin for hosting the "venue" and congrats to Sylvain and Scott for their success.

Q: "each player melded exactly 12 one-suit tiles"
A: two kongs of the same suit (i.e. 8 one-suit tiles) and a kong of wind

So... winds are now suit tiles?
And they are in every suit?
Wow!
Looks like I've misunderstood the question and it was actually an easy one!

I really enjoyed the puzzles, which no doubt improved my mahjong game considerably. They forced me to consider wait situations and patterns which I hadn't given much though to before. Congratulations to Sylvain Malbec! And a great thanks to Vitaly Novikov for conceiving the puzzles, and to Martin Rep and Mahjong News for providing the venue.

I'm not clear on why the time limit was extended an additional three days.

Was it because I was the only one to answer the question within the allotted time?

Just curious.

Thanks.

Fourth deal
At first, it looks like each player had three pure melded kongs, two of them separated by two numbers (e.g. 1 and 4), and that their left-side neighbour is waiting for these two said kongs with a ryanmen (e.g. _23_).
But it turns out there are not enough tiles for that.

So, here's the trick:
Watson had: melded: 1111m 4444m 5555m, concealed: 23s EE.
Lestrade had: melded: 1111s 4444s 5555s, concealed: 23p SS.
Holmes had: melded: 1111p 4444p 5555p, concealed: 78m WW.
Mrs. Hudson had: melded: 6666m 9999m, concealed: RRRR(concealed kong) 23m NN, and erronously melded as flowers: 2223m.

It certainly "cut off all conceivable scenarios".

How many points does Mrs. Hudson have? (Easy ‘Sherlock problem’!)

Sherlock HolmesLast mystery ‘Mrs. Hudson's Problem’ turned out to be a real tough one to solve. Today we offer you a much easier mini-mystery of ‘paramahjong’. Please, try to solve it but ... don't push hard and have fun!

(The solution to Mrs. Hudson's Problem is published here. Please check also Adrie van Geffen's answers!)

Remember: you can find all of Vitaly's contributions here. (In the Extra menu, please click 'Sherlock Holmes Mahjong Mysteries'.)

So, Sherlock Holmes, Dr. Watson, inspector Lestrade and Mrs. Hudson are playing mahjong at Baker Street 221 B.



At the table Mrs. Hudson has:

 dot1-1dot2-1dot1-1bam4-1bam5-1bam6-1

crak7-1crak8-1crak9-1white-1white-1white-1

west1west1

 

 

Last taken tile (from the wall -- added later, V.N.) is west1

Do they play MCR? Did she draw the last tile herself? Is she/the going wind West?

Yes, rules set is MCR. She took tile from the wall (corrected later in original text). It does not matter what are winds in a deal -- let's assume Mrs. Hudson is East and Prevalent Wind is also East.

Vitaly, please make the explanation of the conditions clearer, using official MCR terms. I do not understand what this phrase mean: "At the table Mrs. Hudson has:". Is it her discard? Is it her melded sets? Or both? Or may be it is her concealed hand? Or something else? Or you would like us to guess what it is?

Mark, this mini-mystery goes with touch of humor. We would not explain in details what, where and why has happened with Mrs. Hudson's tiles. Once someone sees multiple opportunities to explore and answer that's even better. Please provide your answer under any possible set of conditions you would read in original text.

Very tricky situation are happen in that case...

All tiles in MJ-set are don't have backs! And, when this deal are played, mrs. Hudson prepare dinner, so she was little scatterbrain. When start-hands are sorting, she accidentally rotate 3 tiles of "1 dots" faces to gentelments! But they used tile-holder sticks, so gentelments can't see this mistake - tiles almost fully hided by sticks! So, mrs. Hudson thinking it was a concealed pung of white dragons, because white dragon in this set looking as clear tile, no any figures.

Thru all game mrs. Hudson trying to collect "all types". It was a nice bonus, when she collected concealed mixed straigth. So, when she taked last tile from wall and it was WW, she count next fans^
1) mixed straigth - 8
2) all types - 6
3) fully conc. hand - 4
4) single wait - 1
5) dragon pung
6) last tile - 8

- Exuse me, mrs. Hudson! - saying Holmes. - It's very strange, but i have white dragons pung in my hand too. So, pls, remove points for all types and dragon pung. When mistake are discovered mrs. Hudson remove 8 pts and add 3 pts for tile-hog and terminals-pung.

well, obviously Mrs. Hudson's points depend on her actions - if she savvily just discards the fresh-drawn third west wind, she still holds in her hand, then it's about zero points in the best case (draw) or minus whatever she'll have to pay the winner at the end of the game...

but if she happily calls "Hu!" and presents her up-to-now concealed tiles it would be -60 by the rules, as she should pay a penalty of 20 to every other player for calling Hu with a dead hand (consisting of 15 tiles) - anyway being a beginner in a friendly game, I guess, Holmes will just blame himself, that he didn't notice the moment, when Mrs. Hudson got a "long hand" and declare the game void... ,-)
