I'd say, they can only be discovered like other math-entities,
e.g. large primes etc. You won't say these were "created".
I assume the reason is that they want to claim copyright
on sudokus for which "creative work" is necessary in most
countries, while discoveries can't be copyrighted.

I thought we were through this already. Euler contributed to
latin squares considerably. Probably more than anyone else
before him and centuries after him. Sudokus are very similar
to the problem of completing latin squares with holes.
So there is clearly SOME connection.

it's generally acknowledged that Nikoli contributed considerably
to discovering sudokus. If "we" wanted to usurp sudoku, we would
give them a different name. So I don't know what you mean here.

I don't know about the latter, so I withhold a comment here ;-)
Just wondering, which non-white guy you want to be included
in the history of Sudoku.

sorting sudokus by difficulty level is even easier (=faster)
for computers than generating them.
Why do you want sudokus printed in book-form, when you can
get them here in internet in computer-readable (and printable) form ?

Collect what you already have, what you find on the web, ask here
