I was pretty into Sudoku when it was the big thing and suddenly all online web apps, shareware apps and stuff were sudoku. I remember my friends and I sharing which of the online flash sudoku were our favorite in terms of interface. That was several years ago and I don’t really do them anymore. That said, I can’t help but want to solve the puzzle if I see someone doing it on the subway.

This particular guy had a printed out web sudoku puzzle and he was writing a lot of numbers per square, in some cases it looked like four of five numbers per square. I think the entire trip he didn’t write a single definitive number. I wrote down the number of the puzzle so I could do it at home. The first five or six numbers are a breeze but then not too long after that my printout didn’t look all that dissimilar to what he had.
