@ hone:
'm just about to tackle your summer break puzzles again, which is not easy.
I remember that we had posted about this before. Unfortunately, those old comments have all been deleted.
If you don't mind, could you briefly give me some more helpful critical tips for the four puzzles (I seem to remember that 5-fish was mostly necessary).
The solution itself you have posted like the puzzles also in the St8ts forum.
If too much trouble for you, no problem.
Thanks

Quite easy, can probably be done without candidates. Needs a simple x-wing to finish it off.

Indeed, solved it without candidates.

Very tricky, stuck at 4 cells solved.
Made use of three xwings, an UR and setti 5.
Then tested J9: no 5 there gave progress until the End.

At 4 solved cells, there is a very simple SI testing F8=5, which solves a couple more.

Then I needed a couple of longer chains - first testing J6=2, then testing J5=2.

The is.gd/... pages do not work. Only a white pattern is shown.
Yesterday everything was correct.

 

by: hone

 
 
is.gd works, but www.str8ts.com/feed/ doesn´t

 

by: Ben

 
 
Here's two ways people can get their str8t's fix:

1. Use: mastertoolworks.com/str8ts/str8ts.html, click Load Puzzle, and enter the is.gd url.

2. Go to the is.gd address, take the long puzzle number, take the first 81 chars and last 81 chars (ie. remove the middle 81). put them together and enter them in the str8ts solver url.

The is.gds are without numbers in the fields.Yesterday I could see them.

Yesterday I emailed Andrew about this problem. The links seem to be working normally today.

But I enjoyed it.

@jk 27-Feb-2021, 14:34
Starting with bca8 solves it

@hp 27-Feb-2021, 15:05
Seems chainy to me, in spite of a swordfish in 8

@marianne 27-Feb-2021, 17:30
Like jk, then there ist an astonishing progress with settis and singles.

Please, is help possible: J4 and G8, where the 1 and where the 3, and has col 7 the number 1 in their upper part?

 

by: marianne

 
 
J4=1, G8=3, col 7 without 1. Have a nice evening.

very nice - B and X power

 

by: effchen

 
 
@Leren, we need yor help. Your puzzles are not working.
Yesterday you could see the numbers, but today there are just empty fields

 

by: BP

 
 
Great puzzle. Used one UR.
@Leren: I printed it yesterday but today indeed all fields are blank like effchen says.

 

by: kmr

 
 
Very nice one which needed all standard tools and BX power. Thank you so much, Leren, for offering these puzzles.

 

by: Susan

 
 
Puh, hard work but managed finally with my second attempt. Thank you!!

My above comment was meant for the B2-puzzle. Now I solved this one, very nice, no UR needed.

also very nice - easier than BX2

Thank you, very nice puzzle which develops smoothly and without difficulty.

Can someone explain to me how you solve this kind of str8ts?

Like Sudoku: Every Block, i.e.: ABC123 must include different numbers between 1 and 9

Hard one, but nice. I needed chains. They focused on the 8, starting in the top middle and in the diagonals.

 

by: jgrab

Add to this thread
 
Rather hard. Took me more than one hour. An early little HC on D2 and a Setti 3 combination (solving B1) brought me forward.

by:Leren

 


is.gd/Leren_558_X1

 

by: jgrab

 
 
A nice one, thanks. It starts from interdependencies in the bottom corners, then careful employment of standard tools.

 

by: BP

 
 
Really nice, especially the start in the corners. Thanks, Leren.

 

by: hago

 
 
Again a masterpiece; thanks, Leren!

 

by: Jan

 
 
Hmm, I get a large gap on one diagonal and in consequence a naked pair in a row as a result of the above-mentioned corner work...but what then?!

 

by: Jan

 
 
Scratch that - I was asleep at the helm regarding the other diagonal!

 

by: Jan

 
 
However, after solving the one cells on the other diagonal and some more nakes pairs, I am stuck again...

One chain did the job:
H1=9? J1=8,G3=6,G7=8,HJ8=6
so H1=5

Thanks for this challenge, Leren!

by:Leren

 


is.gd/Leren_558

Only with chains/guessing in the end.

 

by: BP

 
 
Nice, standard tools and SIs.

 

by: Hago

@Susan: Look what happens, if you set H1=3

Much too easy - the website solver can do it on its own!

Since I don't use solver, I didn't think the puzzle was too easy. It took a bit of work to solve it.
