ThaiDay (inserted in the International Herald Tribune in Thailand) started Sudoku on August 15, 2005. I am in Thailand at the moment, in Phuket, and I'm relaxing on the beach with a cluster of Sudokus in hand.
Pappocom's Sudoku first appeared in the Conway Daily Sun, New Hampshire, USA in September 2004, and it has appeared in The Times (of London) since November 2004.
Don't be put off by some of the complicated-sounding posts in these forums. In some parts of the world they have got quite expert already. If you want help, just send in your question, and you are certain to get a friendly reply.
