I’ve somehow gotten into Sudoku. I’ve been playing through the iOS app Good Sudoku, which has convenient hint / highlighting / annotation features to make solving puzzles faster and less tedious.
I’ve progressed to doing Pro level puzzles (4th hardest level, of 5), but there are a few techniques that I’m still not able to recognize on my own. Currently, I always have to use a couple of hints to solve a puzzle.
I can do Pro puzzles! I’ve tried out the Impossible puzzles, but couldn’t wrap my head around some of the techniques and am not quite feeling up to practicing yet.
