Help with Double Jigsaw Sudoku

Postby DrKelly » Sun Aug 08, 2021 10:16 am

Hi guys,
I desperately need help with this puzzle... I already tried to put the separate Jigsaws in a solver, but they show multiple solutions.
The key here is that the two Jigsaw puzzles have the same solution... But I am really stuck... Please send help!!

I am trying to add a photo of the sudoku, but that also doesn't work. I keep getting this message: "Sorry, the board attachment quota has been reached.
Anyone else knows what to do?

Thank you
DrKelly

You can't attach a picture until you have two accepted posts.

If you are unable to upload the image here:

1. If the image is already available elsewhere, provide link to the image here.

2. You can upload the image to an external file hosting service, and provide link to it here.

3. Use text to represent the image, e.g.
Code: Select all
+-------------------+---------------+
| .   .   .   .   . | .   5   .   . |
|       +---+   +---+       +-------+

                        |   +-------+       +---+       |   |
                        | . | .   6   .   .   . | 2   4 | . |

                        | .   .   2   . | .   .   .   .   . |
                        +---------------+-------------------+

4. Use 2-line jigsaw definitions, e.g. for above:
Code: Select all
grid 1:
......5....2..4....8.....76.16...9........39.23.......69..........836....2.9..... 111112222113122244333155224633555554633355444667777744668777999668788999688888999

grid 2:
.....6.3....583..........27.......93.64........6...24.23.....1....9..3....2...... 999888886999887866999777866447777766444553336455555336422551333442221311222211111

The 1st 81-chars is the sudoku, the last 81-chars define the irregular regions. This is not ideal, as it does not show the overlapped region.

Hi, thanks for your reply.
Ok I posted the photo with an iCloud link, I hope it works.

share.icloud.com/photos/0pshGI-NKUQroYrIisUejTlEQ

So the deal with these Double Jigsaw is that both sudokus have the same outcome. I already tried to put the seperate sudokus in a Jigsaw solver, but they both had multiple answers.... I really don't know how to continu from here......


Thanks so much in advance!

It seems to be two different jigsaw layouts with the extra hint the solutions have to be equal.

Pencilmarks (they are the same for both jigsaws!), if these can be of help:

The Double Jigsaws are solved by keeping the same solved cells and pencilmarks in both grids.

SE Ratings (probably: Medium, or Hard as there are no Singles at the start):
Code: Select all

6...3...5.8..5..7...................31.....92..................43..2..1.8...1...4 ED=4.0/2.8/2.6

Hey! Thanks for your reply.

Yes I already knew that the solution of both Jigsaws was supposed to be the same.
I tried to do the pencilmarks myself, but even then I don't come any further than this...
