Stuck again on Pappocom puzzle

Postby Hud » Tue Dec 06, 2005 11:15 pm

I'm hopelessly stuck on this puzzle and can't seem to grasp how to post a neat grid. Please bear with me on the posting grids and I'll try to learn the "code" technique.

Code: Select all
!2x5!xxx!8xx!
!xxx!x9x!x1x!
!x9xxx7xx3!

!xx3!xxx!15x!
!xxx!4x9!xxx!
!x28!xxx!3xx!

!8xx!7xx!x4-!
!x1x!x6x!xxx!
!xx4!xxx!7x6!


Here's where Im stuck:

Code: Select all
!2     34 5  !136   14   16   !8       79   79   !
!346 8   7  !2356 9     256  !2456 1     25   !
!146 9   16!2568 2458 7    !2456 26    3     !

!469 47 3  !268  278  268  !1       5      479!
!156 57 16!4      3      9     !26    2678 28   !
!469 2   8  !156  157  156  !3      679   479 !

!8    6   29 !7      25    3    !259      4      1  !
!7    1   29 ! 258  6     4    ! 259   3      258 !
!35   35 4  !9     128 128   !7      28    6      !


In one of my attempts, I filled in row7 completely but I couldn't duplicate the feat and still got stuck.

This is ugly and I apologize.

The 6 in box 2 must go in row 1.

if you click quote on the top of this post you will see how its done. if you quote something in code everything is monospaced

e.g... 1 2 3
Code: Select all
 1 2 3


so as long as everything is the same amount of spaces apart, the code looks pretty.

like em said look at where the six goes in the top line, so you know where the six is in box 2, hence can delete 6 from cells in Rows 2&3 in Box 2.

This leads to a Naked pair in Row 2, which leads nicely to a naked single.

From there its basic sudoku stuff to solve:D


Jetshack,

If you are going to post the solution at least say how you got there using logical steps, what Hud was asking for was the next step not the solution, as the solution is no help to him:!:

Thanks to all for the help on this one. The strangest thing is that I usually check for that occurance, but was too enamored with x-wings and x-y wings to take that step. Crazy Girl, I'll have to try out the "quote" system next time. Getting cold here and one of my tomato plants that survived the 115 F heat last summer got a little frost last night.

Hi Hud, Align your grid in Words using Courier font and then copy it into Code when ready.

You do have to space the columns before you code, don’t you?

I monospace the cells.
Then I space the columns = most candidates in column - no of candidates in cell.
Then I code.

It doesn’t seem to matter what font I use, the code button won’t line up columns that aren’t spaced correctly. Am I missing something?

Does anyone have a way of copying Simple Sudoku candidate grids without the brackets? Pat asked this ages ago – I don’t know if anyone answered.

Copy and paste the candidate grid onto Words.
Highlight grid.
Select Courier font.
Use 'Replace all' to remove right brackets and then left brackets .
Add vertical separaters and borders.
Copy into post and Code.

Please let me know if there is a shorter cut.

The version of Simple Sudoku that I have (ver 4.1s -- the current one, I think) doesn't put brackets in the candidate grids.

You're welcome. IMHO, candidate sets are much more readable when they have neither brackets nor digit-separators.

I hear you, r.e.s.. Way back in time, I thought I'd be dead brainy and use Backus Nauer Form to describe my candidate grids but I'm happy to listen to the call of the people. I'll change my source code immediately ...

thanks, em, you remembered!
but - brackets i can handle, i know about Replace All - honest!
the problem is, a puzzle posted like this -
Code: Select all
7[59]4,[259][29]8,631
[1589][1589]2,6[19]3,4[59]7
[159]36,[4579][1479][75],8[59]2
329,851,764
[51]7[51],[94][946][96],283
648,[72]3[72],915
4[15689][135],[259][2689][2569],[35]7[89]
[589][5689]7,3[689]4,12[89]
2[89][35],1[789][79],[35]46
or like this -
Code: Select all
3,1,95, 258,4,7, 28,289,6,
59,24,6, 258,3,258, 1,2489,7,
8,7,24, 6,9,1, 24,5,3,

14,5,148, 48,2,3, 6,7,9,
7,248,3, 9,1,6, 5,248,248,
6,9,248, 7,5,48, 248,3,1,

49,3,489, 1,6,24, 7,248,5,
15,46,7, 245,8,9, 3,16,24,
2,468,15, 3,7,45, 9,16,48,

- i'd like to get the columns aligned
without manually counting the necessary spaces.

- or (better for me),
replace every list of "candidates" with a dot
(as place-holder for an empty cell).
