The real addict has already found it, but those who get their nightmare by other means than the www.sudocue.net website, there is a special treat on the site.

I call it a clueless sudoku, because the central sudoku has no clues at all. You need to solve the 9 other sudokus to find enough clues to solve the centerpiece. Be warned that this special can be difficult at times.

And maybe not for the true nightmare player. Wink

Anyway, feedback is appreciated.

Ruud.

Ruud,

I think this is a very clever idea!

I am saving this puzzle for a time next month when I will be on an airplane for a number of hours.

However, I have observed that the first (top left) puzzle, by itself, has multiple solutions. So, I assume the situation is this:

Apply the usual techniques to each of the nine puzzles to complete values in some squares. Then, use clues in completed squares in the blank boxes (the imbedded puzzle) to make further progress. Go back and forth between the individual puzzles and the imbedded puzzle to eventually find a single, unique solution for the whole thing.

Clueless in Detroit,
Keith

Ruud,

I have not given up but I think this one, like a fine bottle of Port, will take time, and is best consumed in small doses.

I believe the first puzzle (top left) leads to the conclusion its R5C5 is <6>.

I solved it, but it took a long time. Good for a change but not as much fun as a nightmare. I especially liked the symmettry. There is, however a problem in that one error can propegate widely. I misread my own writing, and took a 2 for a 3,with sad results, and had to start over once. Possibly making a list of 18 cells or so that you can, should you wish, look up the answers for to check that things are proceeding well would be useful? I am not sure about that, just speculating out loud ....

thanks very much Ruud. How long did this take you to make?

Sick, Sick, Sick!

That's me I'm refering too. I was browsing around for SuDoku stuff and found this site. Wasn't too long before I found clueless.

I HAD to solve it.

killed 5 hours before realizing I'ld made a mistake somewhere & had to start again.

2nd pass took about 5 hours, but it's solved!

Bravo to the creator of this puzzle.
