The New Sudoku Players' Forum

[Richard S]

Hi all,

I have seen a lot of nice puzzles from quite a few people here, so I like to share a creation of myself with you in return...

I have made a very nice cylindrical sudoku, using the letter S all the time.

Since I have no webpage I can not attach the puzzle, so I give you the link to another forum where you can find it:

Enjoy it!

Since I have no webpage I can not attach the puzzle, so I give you the link to another forum where you can find it ...

You could attach it by using the "url" tag with the other site's image-location:
http://www.sudoku.org.uk/discus/messages/1289/2097.jpg

Alternatively, you could use that location with the "img" tag to display it here:

EDIT: Spaces added to img tag to prevent displaying it here, due to the large file size.
See udosuk's reduced-size image posted below.

Thank's Udosuk,

I am not so good with computers as with puzzles...

Now that the image is on this forum, I can write the instructions here as well:

I have made a very nice cylindrical sudoku, using the letter S all the time.

Fill each column, row and outlined coloured region with the digits 0,0, 1 to 7. (The zero appears twice, to make this one more difficult.)
The numbers outside the grid are the sums of the digits you come across first: the first number (in brackets) is the number of digits you have to add up, the second number is the sum. So (3) 2 means: first three digits are 0, 0, 2 in any order.

It solves without complex techniques, just logic.

Enjoy it!

You've thanked the wrong person, r.e.s. was the one who helped you...

But since you mentioned me, I might as well chip in and thank you for posting a thoughtful puzzle. Saved it already and will attempt it later...

[Richard S]

Oops, sorry both R.E.S. and Udosuk,

I think I badly need a holiday, and that's exactly what I'll do the day after tomorrow...

I have planned to make some nice puzzles of this kind during my holiday. Will post the results here mid august...

In the meanwhile a hint for the people who can't get started:



Don't only look to the given sums, but also to the 'leftover' sums you can find inbetween...

Here is another version of the puzzle pic I made, with (considerably) smaller file size...

Thanks Udosuk,

It looks nice this way.
Since there is at least one person who solved this one, I will give it another go.
I have made four new puzzles during my holiday and will post them here soon, after definitive checking it (made them without computer-help {missed excel, though }, just pencil and paper, and have to last-check a nice excel-print).
I will use all different colours in that puzzles, like you did.

Finally, finally I had some time to write a walktrough for this puzzle.
