## Version history (last 3 releases)

### 1.2.1 — 2026-07-04

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.

### 1.2 — 2026-05-05

Quiet Sudoku 1.2 adds optional iCloud sync for settings, history, and stats across devices. This update also improves the stats screen with current daily streaks and cleaner chart lines when there are gaps in play history, plus disables the iOS Game Mode overlay for a quieter launch experience.

### 1.0.1 — 2026-04-04

No release notes.
