I’ve always loved puzzles in small, stubborn ways—the kind that refuse to give up their secrets at first glance. Sudoku is the one that crept into my life with a quiet persistence. It started as a gentle curiosity on a rainy Sunday, and now it’s the kind of hobby I carry around in my backpack, like a little mental gym that never closes. Writing this feels a bit like inviting a friend over for coffee and rambling about something that’s both deliciously simple and devilishly challenging.
