Thank You, Stefan for this nice afternoon-puzzle with fishes ans Settis.

 

by: Ben

 
 
A good puzzle. I used a simple street interaction for this one also.

 

by: Christoph

 
 
Thanks, Stefan. Very nice.
I used standard tools and an obvious, simple street interaction involving a four cells block.

 

by: jgrab

 
 
Thanks, Stefan. Challenging, took me some time. But it solves from the well-known tools.

Thank you Stefan, same four cells like Christoph ...

by:Berny

 
Stefan, Klaus,
may I politely ask you if perhaps a "more-more" is possible for the last two days of the week?
Thanks in advance! :-)

Full support.

thanks Weatherman for your kind words, but my creativity in this case is normally limited to pushing the create-button in my creator-software...

Nice two-fish-puzzle
Thanks for that, Klaus

Thanks Klaus for this entertaining puzzle.

 

by: jgrab

 
 
I found one a x a-fish on a, and then a Setti. That solved altogether. But it took some time - good entertainment!

 

by: Ben

 
 
I needed a minor street interactions before I couple apply the fish mentioned by jgrab.

 

by: Christoph

 
 
Thanks, Klaus.
I liked it. I used a jelly-fish after a short street interaction between row E and col 2. No UR.

 

by: Christoph

 
 
Very quiet here. Everybody in vacation?
In order to provoke discussion, here my way to solve
(I believe a short chain or street interaction is needed):
To apply a row-jelly-fish on 4 in ABDE2345 you have to ensure that there cannot be a 9 in E. Thus checking E1-E5 is 5-9 leads via E3,E1,F1,F2,E2 and J2 to a conflict.
After this simple head-chain (street interaction between row E and col 2) the rest is straight forward.

 

by: Harm

 
 
@Christoph: this was also my way to solve the puzzle - after trying several other things.

 

by: Ben

Christoph, I used the same approach. There is another street interaction in the first 2 rows that eliminates one of the candidates in A3, but that doesn't seem to advance the puzzle.

@Klaus: although the weather has improved nearly everywhere, I politely ask, whether you have a sophisticated and demanding "322-more" in your locker... my impression is that the "degree of fanciness" of your brilliant extremes is even higher, if there is no symbol, painting or whatever narrowing down your creativity!!??--

by:Jan

 
Always worthwhile to check with the solver...made some simple mistakes manually...but in the final reckoning, only one 3-wing and a series of singles solve this puzzle...oh, and a compartment interaction in row F is also required.

 

by: Klaus

 
 
Hi Jan,

i agree with those who said nothing advanced is needed, no Setti, no wings.

just basic elimination, mostly singles. the solver has problems detecting singles.

 

by: Jan

OK, you're right...I know well that deficit of the solver, but it seems I overlooked a single...

You do need that interaction in row F, though. All the rest is singles.

Nice Setti work
Thank you!

 

by: jgrab

 
 
Very nice! Settis, and then looking out for the wings.

 

by: Harm

 
 
Thank you, Stefan for this Setti-symphony

 

by: Christoph

 
 
Thanks, Stefan.
High/low in A56 is decided by setti 2. Settis and wings and one UR did it for me.

 

by: Christian

 
 
Christoph: I canīt see how setti (2) decides H/L in A56.
At least one of the columns 5,6 must contain 2 but not necessarily both of them.

 

by: Berny

 
 
@Christian:
If A56 = 89, then no 2 in row A (another setti shows that A89=34).
But both CJ5 and CJ6 must then contain 2 (One time 1 to 7, one time 1 to 7 or 2 to 8).
So contradiction.

 

by: CL

 
 
@Christian: In case A56=89, both lower compartments of col5&6 have a 2, so all cols do have. But row A misses the 2 in this case. q.e.d.

For me no UR needed, Settis, singles, 3-wing in the left, large gap & setti 1-6 interaction. Dunno if all of them are needed. For sure a very nice extreme...

 

by: Christian

 
 
@Berny, CL:

You are right of course. I missed a simple and obvious fact. Sometimes one tends to be blind...
Thank you booth!

 

by: Christoph

 
 
Christian,
I just see your question you have asked me. In the meantime it has been answered correctly by Berny and CL.

 

by: Ben

 
 
A56 can also be solved using UR logic. If A56=12, then CJ5/CJ6 cannot both be 3-9, as that would leave A56 free to be switched with each-other (ie. A56 = 12 or 21). Similarly, if A56=89, you know that either CJ5/CJ6 must contain an 8 to lock the pair into place. So, you know that both cols 5/6 both contain 2 and 8 - which also leaves you to use setti 2 to solve A56.

 

by: Leren

 
 
A Swordfish (9) lower right removes 9 from A6 and confirms 9 in CJ 6 => no 2 in CJ 6. Setti 2 then forces A6 = 2.

 

by: Jan

Add to this thread
 
I like Leren's approach best, although one needs the 3- or 5-wing on 4 first and then must make use of the large gap in G5. With all the consequences for the 2s taken into account, the rest is trivial.
