Well, I see. Yes, mystery is important, but let's talk about Sudoku. Imagine a game of Sudoku that gets to the last few moves, just when you have to make the deepest analysis - essentially when you win or lose the game because of your skill - and then, well, you put the puzzle away and keep it in your pocket. You think about it off and on but you don't really make progress. Then you spend an entire afternoon telling someone about the game that you couldn't win. And then nothing. Instead, you say, "Sudoku is important."

I did like the characters. I like the setting - really familiar turf.

That's about it.
