Harder than it first looked. CE and SI, then I chained a lot. At the end there were some non-chain arguments (settis, UR).
The lower right corner can be fixed by unicity, but without consequence on the rest of the puzzle ; there is maybe something more to be done there.


by: Bansasaab

@Fab, Lower right corner is the key. To fix it you have to assume that the other eleminated digits have to come from the related rows or columns above. For example when you fix J8 to 1, the column has to have a 2. That solved it for me.

@Bansasaab: by UR considerations I have J9=2 and J8=1, but that does not mean, 2 is mandatory in 8; EFG 8 must contain 3, but not (yet) 2.
Nice str8ts on a windy day, thanks Klaus!

Nice and challenging. Whole toolbox needed. I used two short chains to decide number 3 and to finish.

Nice one. With the toolbox and skewed fishes / single digit reasoning, I could solve for all the low digits 1-4 (except C4). For the high digits 5-9, progress can be made with fishes and skewed fishes, and a reasoning on the unicity of C4, but in the end I had to use small head chains to unlock (with easy fishes afterwards).

thanks Elf, some wings did it for me


by: Hui Buh

yes, 4 x-wings – that's all


by: jgrab

Wing-based indeed.


by: pets

Thank you, Elf! Though there is no snow in my area, I really enjoyed your sleigh!


by: Jan

Pleasant little puzzle! There are also some nice settis to work on row H.


by: Fab

Indeed, CEs, a nice sleigh of X-wings, and some settis for row H

Thank You Klaus for the nice puzzle!
At 17 solved cells I needed a head chain.


by: ThomasF

thanks Santa Klaus, very nice puzzle, also needed a small head chain


by: KDN

many thanks@Santa Klaus
really nice one, with a short head chain to decide F1


by: milkyjoe

Very nice indeed, cheers Klaus! Managed to solve w/o a chain, there's a very sneaky 4-fish.


by: jgrab

Thanks, Santa Klaus! A good challenge.


by: kolumbus

@milkyjoe: You are right, I overlooked the jellyfish, no chain needed, thanks for the hint


by: Christoph

Thanks, Klaus.
I had used an x-wing and a setti 7 argument.


by: Fab

Nice. CE, UR and wings up to 3-. I was too lazy to look for a 4-wing so used a SI on columns 1&2.


by: Jan

Add to this thread
Yes, that 4-wing really is sneaky!

Christoph, I can't see how a setti 7 argument could work - at least not in the position with 17 cells solved.




by: Chantal

Very funny thanks


by: Hui Buh

Not an extreme one. No advanced techniques required, just simple elimination and singles 8-|


by: Andrejs

It seems to me that this puzzle was good for resting after the difficult puzzles of recent weeks.


by: Jan

Add to this thread
Yes, Andrew's solver manages to solve this by itself when one helps it to discover the two singles it can't find due to a bug.
