### IÂ´ll never be able to solve ANY Sudokus!!! :-(

Hi, all,

I tried to solve an EXTREMELY EASY (!!!) sudoku - in the newspaper "OsnabrÃ¼cker Sonntagszeitung" it is given with the difficulty "hard":

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

I only found out 2 hidden singles (r1c3 = 9 and r9c3 = 3) and a naked single r6c4 = 6... nothing more...so 54 (!!!!!) cells had to be pencilmarked ...

this is the result (but I couldnÂ´t solve it...) - EVERY 6 months old CHILD could do...

Code: Select all
`+---------------+--------------------+----------------+|1256. 1256. 9..|7.... 23456... 8....|34.. 1234. 134..||12578 12578 4..|235.. 235..... 25...|6... 12389 13789||24678 3.... 67.|9.... 246..... 1....|47.. 5.... 478..|+---------------+--------------------+----------------+|9.... 4567. 8..|356.. 3457.... 45...|1... 346.. 2....||14567 14567 567|23568 12345789 24569|3479 3469. 34679||3.... 147.. 2..|6.... 1479.... 49...|8... 49... 5....|+---------------+--------------------+----------------+|24568 9.... 56.|1.... 2568.... 3....|45.. 7.... 468..||45678 45678 1..|58... 5689.... 569..|2... 34689 34689||2568. 2568. 3..|4.... 25689... 7....|59.. 1689. 1689.|+---------------+--------------------+----------------+`

24 given numbers - 2 hidden singles found - 1 naked single found - it is LESS than NOTHING!!!

I hope that dealing with Sudokus causes for me:
- neverending stress
- neverending frustration
- being extremely anxious trying to solve ANY sudokus

Again I need a bunch of tipps and hints - thanks in advance.

Do you know about Locked Candidates?

If you look at block six, there are only two places a 7 could go and they are both in row 5. One of the cells in block 6 must contains a 7, so no other cell in row five can contain a 7.

After that you should be able to finish solving.

hi, JasonLion,

NO, I donÂ´t know about locked candidates - even I am dealing more than 4 years with Sudokus. Normally after that long time I should join EVERY Sudoku-competition and WIN them ALL!!!

Many thanks for the tip with the locked candidates.

Hi, JasonLion,

your tip with the "locked candidates" in box 6 / row 5 was very useful for me. Now IÂ´ve just solved that "monster":

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

Without your help I couldnÂ´t solve it...thanks again!
