The interpreter wrote:I was on the train and was bored. So I did what I always do when I am bored - Sudoku. Then I thought of a little game I could play. I had to average one Sudoku per stop on the train. It is cool to see if people can do it. It would not work if it stops at each block but if it stops in each town then it is possible. I successfully did this - it is a race against time.
