1st two days in a row?
 |  |
10:35 Maen
 |  |
18:32 As usual, just happy to finish the Tough one! That looks like some HOT metal!
 |  |
After set-up, I didn't have the patience to start working through the jumble, so I took one guess. Solving was easy after that! :-)

It looks hot in the foundry.

14:36 A great day here--nice break from the rain, at least so far. Forecast is for a nice weekend; enjoy yours!
 |  |
Good Maen to all. TGIF here :-)
 |  |
7.07 maeN all, easy tough today.

Good Maen to all. 'There will be a hot time in the old town tonight!!'

This is another one that is much easier to solve than it is to prove. Here's a possible proof:

1) Start 22, UP to 25.
2) Naked pair 16 at gi6 forbids d6=1, f6=16, h6=6, g5=1, h4=6. UP 32.
3) Locked 5s at f78 forbid f2=5.
4) Note that i2=5 -- d2=5 == d3=5, and i2=5 -- i1=5 == b1=5 More...
 |  |
My solution is very much like Clark's - although I did arrive at it independently.
1) Start at 22 filled - the given puzzle. Unique Possibilities to 25. (UP 25).
2) Locked 1's at i13 forbid 1 from i6. UP 32.
3) d2=5 == d3=5 -- d3=1 == d45=1 -- f5=1 == f7=1 -- f7=5 == b7=5 -- b1=5 == More...

Hi Clark! Our proofs are essentially the same, except perhaps that I used a few less sets in my step 3 then your step 4. It is interesting that we forbid exactly the same items in each of our last three steps. You have quite a talent for finding fc's - and it is very nice to have others also offer proofs!
 |  |

I couldn't see at the time how to write my step 4 as one chain so I wrote it using the logic that led me to find it. Looking at your chain, I see that I can turn my step into the chain d2=5 == d3=5 -- d3=1 == e13=1 -- e79=1 == f7=1 -- f7=5 == f8=5 -- bc8=5 == b7=5 -- b1=5 == i1=5 More...
 |  |
As people often ask how one finds chains, I can tell you Clark that the technique you described is exactly how I started finding them. After time, the process has evolved for me into something other than that. Today's puzzle, for example: The 37 choice at f2 looked like it would solve a few More...

1'02'29. Sigh. I really want to understand all this and to learn to see the solutions on my own, which I know won't happen without practice. I haven't the time, though, to spend hours on a puzzle! Steve, thanks once again, and Clark, too. I especially liked the exposure of your thought More...

9:19 good maeN all!
 |  |
9:04 with 3 guesses...too tired for any less! Off to bed for me. Good maeN all!

Way outta my depth up here, but enjoy reading the comments.

Larryville - Maybe one possible solution is to open another browser window, resize both so that you have two open on your screen at the same time with all the info you want to see.
Hope it helps.

I completed this without any guesswork BUT used 'Automatically remove Possibilities'. It still feels a little like cheating, but I'm not about to look a gift-horse in the mouth. (And NO Gath, I'm not calling you a horse!!!!LOL)
 |  |
Larryville, do you still lose the workings if you press 'save game' amd then 'load game'?? I find that these work OK if I am only moving around on this site, but that the saved games are lost if I turn the computer off, say overnight. Worth a try!
 |  |
I always try to use guess to finish this tough level
 |  |
 |  |
Larry - I often lose saved games so tend to keep Tough open on a different browser. Occasionally, when I get serious- looking for FCs - I have two browsers (minimised and open) side by side - working on Tough. You can fit 2 puzzles on the screen at once if you move the sides of the browser.
