Hi All. Sorry about the issues around the players falling apart this week. The problem was peculiar to this weeks puzzle in that the numbers were mucking up the solution checker. I've reworked that now

i need help.
the daily puzzle only shows blanks, no access to my daily drug anymore and i'm on cold turkey now.

web admin, please give me back my daily dose

co-addicts, does one of you maybe know the trick how to get charged again?

greets

for first help there are daily Str8ts available at:

For a few days there are only white (empty) squares in assymetrical on the screen. The rest works normally. Even Daily of the same day.

Oh-oh,now the Daily is empty too. Help, please...We miss it!

by:james

 
Daily doesn't work. Weekly works.

javascript console logs:

Uncaught TypeError: Cannot set property 'value' of null
at set_square (ASStr8ts.js?v1.111:113)

note...seems to be trying to load two different verions of ASStr8ts.js . And passing a null which screws up displaying the board.

@james did you report this to Andrew?

by:Chrissie

 
Please, is there any solution for our problem???? I and some other guys see only blank grids. I do not see any numbers or any black cells as well. I tried some different browsers (Chrome, Firefox, Internet Explorer, Edge...), nothing works. It was functional few days back.

Thanks Stefan for this. Quite enjoyable if one doesn't mind URs. I don't know the difficulty level of this for folks who don't like URs.

 

by: jgrab

 
 
Very challenging! However, I found my way into the puzzle through large gaps, particularly D9/G9 and its consequences on B9. Only towards the end, one UR helped. So there may be different approaches.

 

by: Leren

 
 
Solvable without URs with a short chain/Street Interaction near the end.

 

by: Harm

 
 
I also used one UR in the end - thank you, Stefan for this nice puzzle.

 

by: hone

 
 
Thank you for this nice pattern.
As there is symmetry a skewed variant can be derived

one of the best CEP i ever made, thank you very much Stefan very nice pattern
my way was a hidden quadriple, xwing on 3, pseudo large gap row J and finally a UR wiht Impact for F4,

 

by: Christoph

 
 
stefan348a:
a really excellent challenge, Stefan.
I used ( maybe not all needed):
4-cells-street interaction excludes 1 from J7, then large gaps, 2 URs, and a couple of xwings. No chain needed.

 

by: Christoph

 
 
I have forgotten to mention 2 or 3 settis.

This puzzle is really excellent...I have never seen a situation like the one in column 9 previously, where two large gaps cooperate to make progress! And "large gap" seems to be the theme of this puzzle...

So the large gaps in D9, G9, J4, F1 lead to a lot of progress, then there is an x-wing 3 in between, later you have a 3-wing 8 and an x-wing 7. This gives you 30 solved cells. Now you either use a chain to decide which column is without 8, or there is a UR in the upper middle that also does the job. Anybody with a better alternative in that position...?

by:TheWeatherman

 
@Klaus/Stefan/Leren et al.: the weather in nearly whole Europe is deteriorating in this weak... a nice and sophisticated extreme could improve the situation considerably!!!--- Many thanks in advance for your understanding and support!!

 

by: Berny

 
 
General agreement!

full support - although I can´t argue with the weather (in northern Portugal we currently have a sunny spring)

by:Leren

 
I have checked Andrew's puzzle in his solver. It gets to 35 solved cells where there is an obvious single 3 in A7 that it does not see. Putting the 3 into A7 then the solver manages to complete the puzzle.

My understanding is that if Andrew's solver can solve a puzzle it should not be put up as a Weekly Extreme. I'll report the bug to Andrew to see what he does about it.

 

by: Leren

Add to this thread
 
Andrew replied to my email and said that he was aware of a bug in the Str8ts solver whereby the correct solution isn't recognized, and he was fixing it. Maybe that will address some of the problems mentioned below.

by:kri54sub@yahoo.com

 
Seems like there is a problem. I see only blank grids.I do not see any numbers or any black cells as well. Tried both in Chrome and Firefox (latest versions as of 2/19/2017). It was functional few days back.

 

by: Anna

 
 
I encountered the same issue... I used Chrome and Safari for Mac. I didn't do any browser updates recently, which could explain the issue. Would be great if that could be solved. Was looking forward to this week's extreme str8ts :)

 

by: Chrissie

 
 
The same problem at my side - only blank grids.

 

by: witch

 
 
same here. for all my browsers :'(

 

by: jgrab

 
 
On one of my computers, I encounter the same problem (with Firefox). Only blank cells. However, if I use the print option, I can make the puzzle visible - at least.

 

by: Anna

Add to this thread
 
Thanks jgrab for the hint :-)
I copied the print version into the solver and was able to solve it online. That seems to be the only fix that works.
It requires a bit of an effort, but it's worth it.

This one seems easy. No Setti's, wings or URs.

Thanks for the nice puzzle - done by fishes and x-wings

 

by: kolumbus

 
 
I liked it too, thank you Stefan!
Besides wings and fishes, careful elimination is required.

 

by: ThomasF

 
 
thanks Stefan, very nice. Wings, fishes and CEP

 

by: Harm

 
 
Thank you, Stefan for this chainfree puzzle.

 

by: jgrab

 
 
Thank you, Stefan. Very good and interesting - on an excellent extreme level.

 

by: hp

 
 
excellent puzzle ty Stefan
shortest path i found:
xwing on 8, swordfish on 8, Jellyfish on 2, jellyfish on 5, xwing on 6 and solving

 

by: Jan

 
 
Seven cells solved, after the two wings on 8: IMO, there is no 4-wing on 2 because 2 ist not a must in C1-6.
There is also a 3-wing on 4, but it doesn't help over and above the other mentioned wings.

 

by: hp

 
 
@ Jan:
you are right, that was a lucky failure of me.
Now i must look to antoher path

 

by: Ben

 
 
I was able to solve 8 cells using wings, then I needed some simple logic to solve J1, and the rest was straight-forward.

 

by: Leren

 
 
At 7 solved cells, after the xwing on 8, there is also an xwing on 7 in FG23 that hasn't been mentioned. Perhaps that will clear up some solving problems.

 

by: Christoph

 
 
Ben,
After having solved 7 cells (A6,B67,F7,G67,H1) I had solved it via a chain testing E1.
What was your 8th solved cell ?


 

by: Christoph

 
 
ok, now I see the solved cell number 8. It is C5, solved via a j-fish on 5. I had not seen that fish in my first approach.

 

by: Christoph

 
 
Now, having solved C5, you can exclude the high candidate in C4 (by analysing C4-F4) and thus the high candidate in C1, which solves E1 and thus the puzzle.
Excellent puzzle, Klaus!

 

by: Christoph

 
 
Sorry, Stefan. It is your puzzle, not Klaus'.

 

by: Jan

 
 
Sorry, can't reproduce that jellyfish on 5!

 

by: Ben

 
 
Jan, the jellyfish in the last 4 columns.

Thanks Christoph, I totally missed the eliminations in CDEF4. My alternative solution was that if E1=8 row C would include a 2, so row J could not include a 2. So, either solution for E1 resulted in J1=3.

 

by: hp

 
 
yes that's it the Elimination in C4 and C1 is the key and replaces the jfish on2.
nice path

 

by: Jan

Damn, dunno why I didn't see that! 8-) - Thanks!

And it's a nice elimination in C4, none too obvious...
