29 minutes. is no one else out there??

See you guys Tommorrow. Have a good one.

here is already tomorrow, hello everyone :)

Am I right in guessing that the photo is the big wheel in London? I've only glimpsed it briefly.
Time for bed. Goodnight Everyone.

THE LONDON EYE!!! I LOVED IT THERE!! IT WAS SO BEAUTIFUL. AND THE VIEW!! LOVED IT!!!!!!!!!! Im going to see if i can go again this summer!

nice wheel
out to the frozen H2O

Didn't time myself today - but I alwasy have to guess one - any ideas on the logic?

I have been there. A view of the County Hall taken from Westminster Bridge.

Help! Stuck on 29.

I always have to guess one too.

This one seemed really tough. Took forever. Needed a ridiculously long FC.

Well, I did this one without guessing. Perhaps I'm improving? Lauren, it's been many months for me, so methinks you just need to keep at it. Eventually everything will 'click'.

Well, this one has me beat. Stuck at 29 filled in.

Hi erik, today's puzzle is the toughest type among the 5 types appearing here (21->27 type). I needed a 10-fc at 29 filled, I used :

(i2=3)==(i2=7)--(i6=7)==(i6=1)--(h5=1)==(h3=1)--(b3=1)==(b3=2)--(b2=2)==(f2=2)

In words, look at only possibles h5=1,h3=1 in their col. Whether More...

what's the trick?

15:20 with two guess, both right... so no mistakes

23:39

50:42 with breakfast, email two phone calls and lots of errors

at least got the chance to see the picture.

cheers

Oh my goodness, it took me 25:48 minutes to do this one. It's the hardest one I've done yet. I couldn't find a way and I'm sure I guessed at a few, but I couldn't get a grip even after learning my new techniques.

12:37 very hard I had 2 good guesses or mabye it was logic???????????????????????????

22:05 With 3 guesses, 1 wrong. Sigh.

Really hard. I tried evrything and ended up needing two guesses. Time was execrable!

gb - I cannot remember with enough specificity to give a proof at this point, but it was along the same lines as yours. I remember i6 being the focal point, but that is all. I think at one point I had to assume two (somewhat) independent) cells to eliminate a possibility. It is comforting to know that this was the hardest type of puzzle!

Wow, 22 minutes in and I am too stir crazy to finish without guessing (so will come back another day and try again). Even with gb's post I couldn't figure it out!!

16 minutes. who IS that woman on top of the timer???????

hello polly dear

WHO IS ON TOP OF THE TIMER SHE IS MAKING ME SICKKK

Been there too! Unbeleivable for a girl from a little country town in outback Aus, to live in NY, to work in NY and travel to the London I

21:29

A possible finish at 50 filled :
One of a9=4, d9=4, i9=4 is true.
If a9=4 then g9=3 so i9=2 or i7=2
if i9=4 then i7=2.
if d9=4 then c9=1.
So one of i9=2, i7=2, c9=1 is true.
But if i9=2 or i7=2 then i1=1 so one of i1=1 ,c9=1 is true, eliminating c1=1.
Then easy to end.

???

Got to 29 filled OK then followed through the chain from gb OK. One guess at about 70 I think for which I am ashamed! But it was right- didn't seem to have a problem at 50 which gb referred to. At least I'm 'seeing' places more quickly now. Time for a stiff 'coffee' and bed!
