Was pleased to complete theguardian’s “hard” sudoku puzzle today in 9 minutes, so I think I’m returning to form. I managed yesterday’s hard kakuro in 17 minutes, which is an improvement. I still prefer to kakuro to sudoku as it requires much more thought and actual maths.
Sadly, I only found out about the 1st World Sudoku Championship today. (Via.)

It took me 18 mins (including a quick trip to the loo in the middle – so discount whatever you will). But I suspect you are more than twice as good at numbers than I am.
