I don't know how long it's been there, they describe it as new, but I noticed for the first time today that UK Channel 4 TV now has a daily sudoku puzzle on Teletext page 142. Today's has 29 given numbers, which indicates that it's fairly easy but, if you're in need of a "fix" and you've nothing else!
Is the number of given numbers as good an approximate indicator of puzzle difficulty as I presume it must be?
