Cheers!  Makes me feel better, anyway.  I'm off in la-la land right now, but once the Hubble deadline is well out the way... watch out!

I don't stumble much better than that.

Hit reset twice in the same position (only a few automatic lines from the end), convinced I must have made a mistake because the puzzle looked impossible now. The third time I went through real slowly and carefully but still found myself in the same position. This time, however, I realised that it could indeed be finished. What had happened was that I ruled something out because it created a loop, then later found I still had two lines running into the same narrow region where they'd be forced to meet. The fact that the _other_ ends of the lines didn't meet this time around managed to completely escape me.

I can't say I'm glad, as that sure doesn't help our crusade for topping the current best ever total.  Do better tomorrow!!

And you survive still!!

Crusade? Not sure I like the idea of that!


Anyway, I've done my bit to help "The Cause" - we're down to sub-30mins now

Oooh!  I've seen a new pattern!

The two bottom corners each have it in today's puzzle, and it's a very rapid solve compared to the trial and error method.

Wish I'd spotted it before doing trial and error though - it would've taken at least another minute off the clock.  Damn!

Does the pattern have 5 numbers in it?   Just wondering if you happened to simplify it more than that.  Their sum is 12.    I'm still looking at it to see if I can simplify it.

It's interesting.  I've seen 3's and 2's before, and wondered if there was a pattern...  Especially

Which always catches my eye, and I think there should be something there, but there's not.  (to my knowledge...)

Yes, and there sum is twelve.
I can get (by memory) 5 lines and a cross.  There are two possible solutions beyond that, which are a lot quicker to work through than without the first bits.

This pattern I've known about for a while; you can get 3 lines and a cross from it:-


(assuming the 3 is in the bottom-left corner)

I'm guessing yours is just an extension of that?

Yes, I was just extending from that to get the extra two lines.

Let's have a think... 
Blocking off the top left gives you:

The only other place that gives you any immediate lines is if you do the inverse to the lower 3.... or, if you have a line meeting one of the corners on the two. 

This can be a fruitful place to make progress, but only when you start with some extra information.

That's new to me as well.  But can't you get 4 lines & a cross?

I don't think that's true.

Even if the ?'s are all x's, it's still a valid alternative, given a blocking of the top left.

Whoops.  Forgot about that option.  Probably explains my times this week!

And it's a "yes" from me too! I'd forgotten that last line...
