The Puzzle That Refused to Stay a Puzzle 
The first time I played Sudoku, I didn’t get it. 
All those numbers, all those boxes — it felt like trying to organize raindrops. I filled in random squares, second-guessed myself, and eventually gave up with an impressive combination of frustration and boredom. But something about it lingered. Maybe it was the simplicity. Maybe it was the faint promise of order beneath the confusion. Whatever it was, I opened the app again the next day… and the next… and the next.
