A number of years ago I found a Sudoku puzzle in a newspaper on a train. I rather liked it and so looked for more. I don't do them compulsively but now and then I have phases of doing them. This is a blip of a "The Times" "Samurai Su Doku" that I have a book of. They look a little more imposing than the regular ones but are on the whole easier I find - but longer.
Anyhow another busy day but this one benefited from dry feet.
