Latimer - That was an easy one! Thanks for the pleasure. Can't wait for the next one!


26' First time ever to get one of these solved! Need to train Settis more...


by: kolumbus

Hi Tom, welcome.
Setti's rule really is a powerful tool; however in this case it's not needed, the col-swordfish on ABD123 tells us that compartments B1-5 and D1-6 must contain 2, which solves the rest easily.


by: morl

however, for some people (including me) it's easier to see a Setti than a fish.


by: Andrejs

It is also my case. After CE (especially in column 7) the
Setti was my only tool.

Sorry, I made a mistake: especially in column 8 (not 7).

X Puzzle


by: ThomasF

thanks Stefan, that was a really nice one


by: Harm

Thank you Stefan. I needed the X until the end.


by: jgrab

40 min; step by step with standard tools. Thanks!


by: hp

puh very hard, but doable without chain Need the whole Toolbox
Thank you Stefan, undoubtedly another X masterpiece


by: aw

I really appreciate being forced to do X-Versions by this Advent calendar - the frequent problem is that somewhere in between I forget about the X and worry about uniqueness :-) Really a nice and doable one - thanks for all those puzzles!


by: kolumbus

Very nice and challenging, thank you, holy Stefan!
The key for me was CE on A-D4.


by: Jonas

May someone explain to me the "X-Factor"? Is it a tool?
Thanks in advance


by: Christoph

Jonas, you have to apply for the diagonals A1-J9 and J1-A9
(this "X") the same rules
as for all the rows and columns.


by: Christoph

Excellent X-str8t, Stefan. Solvable without chaining. Thanks a lot.
