What barks, has four legs, wags its tail, and eats concrete?

A dog.

But the concrete made it a hard one

No it doesn't, it is a CONCRETE-EATING DOG, my neighbour's dog does that, not sure if it was before or after it had the spinal surgery though

One more try on Ruud's birthday:

From the first 4 cells on the top row, it reads 2 3 1 58, so 23th Jan 1958? These cells were originally clueless.

Please at least tell me if there is any part (day/month/year) was right, or am I on the right line. The year 1958 was tried before...

Please at least tell me if there is any part (day/month/year) was right

The day is correct.

What cannot be found in the solution of a proper Sudoku?

Unfilled cells? Cells with candidate markings? Number of duplicate solutions (in that case 3)...

Is the day 23 coming from r1c12 or other info?

The unsolved cells are on rows 1,4,5 and columns 2,4,6 and nonets 2,4,5... Are these relevant?

I think I spent way too much time on this...

[tarek]

thanx Luna & udosuk,
As Ruud confirmed the day &

What cannot be found in the solution of a proper Sudoku?

the first line of the grid supplied by udosuk would be: (replacing cells with more than 1 candidate with a 0).

231060= 23 October 1960

tarek

[Ruud]

A 10?

Yes ... and?

I think I spent way too much time on this

Only a few seconds more, to read Luna's answer perhaps?

231060= 23 October 1960

Correct.

If I have seen farther than others, it is because I was standing on the shoulders of giants.

Couldn't have said it better.

Ruud.

[udosuk]

Thanks! I just need to know the solution after spending so much time on this!

So your birthday is almost exactly 6 months away... Let's send some (very) early birthday greetings!

Have I been the giant providing a shoulder for others to stand on this time? Sounds like the story of my life...

BTW I must confess I read Luna's post before I replied, yet I couldn't work out the "zero" from the suggestion of "ten"... Just haven't got tarek's vision...

So your birthday is almost exactly 6 months away... Let's send some (very) early birthday greetings!

Yes, indeed.

BTW I must confess I read Luna's post before I replied, yet I couldn't work out the "zero" from the suggestion of "ten"... Just haven't got tarek's vision...

Which is further than I got .................

[tarek]

I assure you giants, you do not want to have my VISION

Anyway, what happend to the concrete-eating dog???

[lunababy_moonchild]

Anyway, what happend to the concrete-eating dog??? tarek

Would that be a SETter? (red setter, Irish setter ......)

Luna

[tarek]

tarek

[emm]

Wasn't the concrete just put in to make it hard?

[lunababy_moonchild]

The dog would certainly be well 'ard!
