Good Sudoku

“Sudoku as a concept is in something like the public domain and so Sudoku games tend spamward. “Good Sudoku” is a carefully designed, real effort of a Sudoku app that is worth buying and using instead of weird free Sudoku sites. It’s a thing that everyone else is doing badly done well.”

“Good Sudoku taught me how to play sudoku! I go through wild bursts of obsession with this game every 6 months or so.”
