The world's gone Su Doku mad. (Okay not the world but British newspapers. A little hyperbole never hurt anyone. If it did I'm sorry.)
There's The Times arguing that its puzzles are the original and best. The Independent now offers three puzzles everyday. And the Grauniad offers a hand crafted puzzle (as contrasted with the computer constructed others).
At least it's a reason to still buy the Grauniad now Aaronovitch is leaving.
