What’s new
Version 1.1.0 · Updated August 25, 2026
This update improves puzzle reliability and fixes several gameplay issues. • Improved puzzle generation: every puzzle is now guaranteed to have a unique solution. • Timer fix: it now resumes correctly after the app has been in the background. • More reliable hints: they can no longer place an incorrect number or be used without placing anything. • Daily Challenge improved: a new puzzle now arrives at midnight in your local time, and streak tracking is more reliable. • Better support for external keyboards, including AZERTY layouts and numeric keypads. • Premium is now restored immediately via iCloud, without having to restart the app. • Automatic notes now update when entering as well as erasing numbers. • The on-screen keypad no longer incorrectly disables a number after wrong entries. • Undo no longer leaves a game marked as completed. • Games lasting more than one hour are now displayed correctly on the victory screen. Your statistics, records, and trophies are preserved. Thanks for playing Sudoku!
