Why, did Metro have to put this stupid puzzle into their paper? This is now the second Sudoku puzzle that I've completed while commuting. I started it on the train on the way into work yesterday. Then left the paper at work, went out with Rob from Londonist in the evening and then coming home, I picked up another copy of Metro, started it afresh and finished it and in doing so missed one of my stops, as I was so busy concentrating on the stupid thing!
D'OH, D'OH, D'OH.
UPDATE - OHMIGOD - I completed my third Metro one this morning on the way to work in record time (for me) - I think I need help!
