Did you actually try to solve it in different ways?

And who exactly is that? I assume you realize that, for example, people
from Alabama pronounce English rather differently than people from Britain,
Scotland or Australia? The exact same words may be pronounced rather
differently in these English-speaking countries.

English is not much better. It depends on where you are from how you
should pronounce something.

"The quantity of consonants in the English language is constant. If omitted
in one place, they turn up in another. When a Bostonian 'pahks' his 'cah',
the lost r's migrate southwest, causing a Texan to 'warsh' his car and
invest in 'erl wells'."

Uh, shouldn't that be (9!)^9 instead of 9^(9!)?

Yes. You are right.
Btw, 9!^9 = 109110688415571316480344899355894085582848000000000, which
would be the total number of possible combinations of those numbers.
(Of course only a small percentage of all these combinations form valid
sudoku solutions, and if equal all symmetric positions, it gets even
smaller.)

I mean: did you get two different solutions, or did you arrive at the
same solution by two different paths?

I was assuming (as do most others I think) that sudoku problems only have 1
unique solution. What would be the point of an empty grid?

However most people would rather use trial and error than go very deep in
logical deductions. ie write a 3 in lightly and fill in a few more squares
based on that, oops no that doesn't work, original square must have been a 6
then. Isn't trial and error a form of deduction anyway?

They probably pronounce sudoku in their local accent though, you would sound
a bit weird and out-of-place if you tried to sound exactly like a Japanese
person saying it outside of Japan.
So what you're really trying to explain to people is that the Japanese Su/Ku
letters rhyme with the English words "do" and "to", and the Japanese Do
rhymes with a quickly spoken "saw" (OK those might not be the only or most
accurate English words, but you get the idea). If you pronounce the words
to/do/saw differently, then chances are everyone is going to pronounce
sudoku differently anyway, so you'll be fine.

God help me if I ever talk like that.
We need an agreed upon pronunciation standard that A) is easy to
understand for the majority of folks on here, and B) Won't get Warp's
hackles up.
