I've been buying both the Guardian and the Independent for years so that I could do the cryptic crosswords while commuting (there wasn't room to read broadsheets in the rush hour...). Now that the Independent has Sudoku on the back page, I've been diverted to Sudoku before getting to the crossword.
It took weeks before I could do an easy Sudoku, but then I tried at home. The main problem with doing newspaper versions is the lack of space for writing in the options, so I've finally got round to trying it on computer, which allows different font sizes for possible numbers.
Alanabit - I did the Araucaria crossword today between Harrow and Westminster, and was feeling very chuffed, but then made the mistake of trying to fill in the Independent quick Sudoku too quickly and came unstuck!
