the smith has more to teach, and more to say.
the smith's apprenticeship — two short lessons that teach sudoku itself: the one rule, then how to read the board. new to sudoku? start here.
the smith's forge — a limited build event. every solved puzzle adds a piece to something bigger. miss a day? nothing resets.
the smith has more to say — new lines for milestones, rebuilt streaks, and the hours you actually play.
polish is now picked up from your phone automatically.
