Yeseterday’s Observer sudoku took me 2 mins 51 secs to complete – possibly my fastest time for any sudoku. It’s been going for three weeks now – time to make it a little harder, I think.

The Independent‘s Super Sudoku on Saturday (try saying that without your teeth in) took 110 minutes – pretty good, I reckon, for such a large puzzle.
