I found some web pages that indicate that Su Doku first appeared in
in The Times one year ago today (Nov. 12).
Seems like an occasion to celebrate!
Then I found this page in the Times on-line site. It's a little confusing because the date of the article there is 11.12.04,
and it states that Su Doku will start on Monday (11.15.04). But the same page includes
several puzzles, leading me to believe that they were published along with
the article on 11.12.04.
So, I am curious ... can anyone please verify the date of the first Times puzzle?
