a little something is needed here. mine was that H7=5 leads to an immediate contradiction to Setti on 2.

 

by: hoke

 
 
Tried WC, gave up, then saw, that C4 could have been solved with a bit more thinking. Probably the rest then also.

 

by: effchen

 
 
more solutions are possible,I found one with H7=4
and after that I tried the hint from Klaus and yes it is possible with H7=5 and than you have two possibilities for H4
the 6 or the 9......so we don't have one single solution this week.....maybe confusing for some of us :-)

 

by: Klaus

 
 
yes effchen,

confusing, dont know what your talking about. H4=7 is fixed early on by Settis.

in all the years (and i've been around almost from the very start) i have never witneesed a non-unique solution in Andrews extremes, and this one is no exception.

Towards the end, E2 is either 7 or 24. Both leads to G7=2 via easy head moves.That was my "little something"; if I remember it correctly.

 

by: effchen

 
 
Hey Klaus
H7=4 not H7=5 like you wrote in the beginning
and with a closer look, yes H7=5 is not possible.
I am always solving with pen and paper and now i saw yes it is just one wrong number, but you are right, not possible.
But my first solution with H7=4 is the right solution and without your wrong information i would not try the second possibility :-) Just to clear that :-)

Thank you, a nice puzzle, but also a tough one, needed a small chain.

Tough indeed, but instead of a chain we used a very skewed xwing.

Thank you for this great puzzle. Develops step by step and asks for all techniques.

An excellent start into another str8ts week. CE and B setti power. Many thanks!

On the first glance it seems insolvable, however tiny SIs remove one digit from C7 and another from F6, the rest is a bagful of common steps, including some important hidden pairs and skewed wings.
Very fine puzzle, thanks Leren!

Tough nut, very nice start with a hidden pair on /, then it took us ages to see the SI/setti combination that solves. Thank you, Leren for all the extra fun.

Challenging, but doable. Settis help, and wings - as always.

 

by: Cosmanita

 
 
Same as jgrab. I also needed chains starting in D and in the diagonals.

Like jgrab. Fun!

Joyous puzzle! An excellent way to celebrate & I love the fact that it solves from the middle. Thank you, Leren!

27 min; not sure whether I used logic or followed an intuition ...

Nice puzzle, one fish and some wings did it

 

by: KDN

 
 
Thanks@Leren
Nice pattern ;) nice level of difficulty. Like pets, the key is in the middle...

Nice and quick and an excellent pattern.

Reserved for discussion of Andrew's puzzle.

 

by: Cosmanita

 
 
I also needed a small chain, but an obvious one. I tried all options in E2 + setties with a close look on G1 and G7.

I couldn't solve the puzzle without chains. I selected cell C2 with candidates 5 and 6. A relatively long chain with 5 led to a contradiction, but with 6 I get a complete solution. A much shorter head chain with the starting cell H7 was found by Klaus (see above). Thanks for the puzzle and comments!
