What's New in Quiet Sudoku
1.2.1
July 4, 2026
Quiet Sudoku 1.2.1 makes the Stats screen more focused and more useful. Stats now default to games completed without mistakes, so best times, streaks, solved counts, and completion trends reflect clean solves unless you choose a different filter. Best times are also easier to inspect: tap a best time to see the completed game details, with the same replay and sharing options available from History.
