About 20′, surprisingly. Ideal to approach through several ‘advanced’ URs (I used 5 or 6 of them, the crucial with Y-wing-like logic for the middle columns, + some smaller fishes). Just for curiosity, I am going to manage it without URs now… :-)

(Not all URs have been ‘advanced’ – only three out of five I found have been larger than a 2×2 block, two very useful though.)
So, tried again w/o URs or chains: one variable 6-fish, dependent on the conflict within col. 6, and another four smaller ones should be enough!
Nice puzzle, thanks…

Another masterpiece. Chain- and UR-free fun. Thank you, hone!

Chainfree, but very challenging. High level of difficulty ;-) .

Excellent chainfree challenge. Our crucial step was CE in box 1 to show that 4 in B.

Very nice one, no chain needed, and - like Susan - good level of difficulty. Thank you, kst.

after 19 solved cells I'm stuck. Wonder where to continue, any hints?

Like Augenweide. Susan and kmr, to the rescue, please ;-)

I needed two HCs: E3=7 causes B2=7 and B5=3, but also E2=6, J1=6, H1=7, H8=8 and H5=3. So E3=2. Now H5 cannot be 3 because of the x-wing 3 in DF68 which would place 3 in A3 and there would be no 3 in row B. So H5<>3, which solves this quite hard puzzle.

@morl: your chain is shorter than anything I tried before, thank you. Still too long for my head

Great challenge. After 27 solved cells needed a short SI/setti consideration.

Thanks for this truly nice puzzle.
I didn't manage to do it without a head chain: Both candidates for H1 lead to the same range for D21. With this insight the rest was of normal difficulty.

 

by: AndreasM

 23-Jan-2022, 12:35  
 
Correction of the above: It should read 'range for D34'.

Great puzzle. CE, settis and some SIs. Many thanks.

rather easy, one UR argument is enough.

funny thing: you can give practically the same argument horizontal or vertical, dont think i've seen something like this before.

WC, one X-Wing is enough.

 

by: morl

I agree, it is quite easy. Just Setti 6 and it's solved.

 

by: Andrejs

 24-Jan-2022, 12:51  
 
Since the sure digits in column 5 are 1,...,7, I could easily use my favorite Setti/BCA. Good relaxation.

 

by: glani

Hallo Jens, Setti 6 is easy. But what is WC an where is the X-Wing?


 

by: Jens

 25-Jan-2022, 07:39  
 
@glani:
Without candidates = WC
X-Wing is in BC59, which clears col5 and solves the rest.

It's so clear and I didn't see it. Thanks!
