Sudoku isn't about numbers - it's about patterns and logic.

I became a cryptic crossword addict (and learnt the shortcut codes) at school when we could get the Times at half price, and had a syndicate to solve the crossword....

then I became a commuter on the London tube and did the Guardian and Independent crosswords on the way into work because there wasn't room to open and read the papers...

Now I start with the Independent quick Sudoku, because it's on the back page, and work through the cryptic crossword on the previous page, then the Guardian cryptic crossword. Sometimes the crosswords last till the journey home so I get to do the Guardian2 and Independent Extra Sudokus

It's a great life being a commuter on the London underground!
