### THAT SUDOKU-IDIOT (!!!!!!!!!!) TRIES TO SOLVE THIS SUDOKU...

Hi, all,

again here is an EXTREMELY EASY Sudoku (!!!) which I - THAT SUDOKU-IDIOT IN THE WORLD - couldnÂ´t solve.
It has 28 clues - number: 650036 - difficulty: very hard:

Code: Select all
`+-----+-----+-----+|. . 4|5 . 6|. . 1||. 7 .|. 4 .|6 5 .||5 . .|. . .|3 . .|+-----+-----+-----+|. 8 .|. 9 .|5 . .||6 . .|. . .|. . 8||. . 7|. 2 .|. 3 .|+-----+-----+-----+|. . 5|. . .|. . 4||. 9 2|. 3 .|. 6 .||7 . .|2 . 9|8 . .|+-----+-----+-----+`

I only could find a naked single in r9c8 - r9c8 = 1 - so i had to pencilmark 52 (!!!!!!!!!!)cells!!!

Code: Select all
`+----------------+----------------+---------------+|2389. 23... 4...|5.... 78.. 6....|279.. 2789. 1..||12389 7.... 1389|1389. 4... 1238.|6.... 5.... 29.||5.... 126.. 1689|1789. 178. 1278.|3.... 24789 279|+----------------+----------------+---------------+|1234. 8.... 13..|13467 9... 1347.|5.... 1247. 267||6.... 12345 139.|1347. 157. 13457|12479 12479 8..||149.. 145.. 7...|1468. 2... 1458.|149.. 3.... 69.|+----------------+----------------+---------------+|138.. 136.. 5...|1678. 1678 178..|1279. 1279. 4..||148.. 9.... 2...|1478. 3... 14578|17... 6.... 57.||7.... 1346. 136.|2.... 156. 9....|8.... 1.... 35.|+----------------+----------------+---------------+`

Any tips and hints will be appreciated. Thanks in advance

You should be more careful when writing your pencilmarks and exclude those values that don't fit in the cell. Have a look at r8c7 for example, can it really be 1? There's a lot more singles to be found in that puzzle. Then you need some more advanced technique later in the puzzle. Let us know if you get stuck on that point.

Hi, RW

thanks for your tips and hints. But I am stuck (MUCH TOO EARLY as the WHOLE WORLD knows!)

Code: Select all
`+----------+----------+---------+|239. 23 4.|5... 7 6..|29 8.. 1.||1239 7. 8.|139. 4 13.|6. 5.. 29||5... 6. 19|19.. 8 2..|3. 4.. 7.|+----------+----------+---------+|1234 8. 13|3467 9 347|5. 27. 26||6... 23 39|37.. 1 5..|4. 279 8.||49.. 5. 7.|468. 2 48.|1. 3.. 69|+----------+----------+---------+|3... 1. 5.|78.. 6 78.|29 29. 4.||8... 9. 2.|14.. 3 14.|7. 6.. 5.||7... 4. 6.|2... 5 9..|8. 1.. 3.|+----------+----------+---------+`

I only could find 23 more hidden singles - much TOO LESS

NoClue, via PM you were asked to modify your behavior on this forum. I see no change whatsoever, so again:
• Stop the self-pity party, and
• Stop including links to speedsudoku.com
• Stop yelling, especially in thread titles, and

Have a look at candidate 9 in rows 1 and 6. Can you derive anything from this?

Perhaps it could be a good idea for you to pick up some sudoku software that can help you learn how to use more advanced techniques. Simple sudoku is one easy to use software that can solve most puzzles presented by sites like websudoku and tell you how to do it. Then you wouldn't need to post every single puzzle you come across here. There's plenty of other free software around as well with different techniques implemented.

Hi, RW

thanks again for helping me further. But i canÂ´t derive anything from your message" look at the candidate 9 in row 1 and 6". I only see that it canÂ´t be an X-Wing...

No X-wing, but a finned X-wing or skyscraper, which has been explained to you in several of your earlier help requests here on the forum. I suggest you take a look at those and try to understand what the helpful replies you've got actually meant. Or then you can look up the techniques in some technique guide. There is no point in me telling you what candidate to eliminate if you don't even try to understand the technique. If you want to learn how to solve sudokus like these, then you must learn to apply the techniques yourself.
