Killer Sudoku

Killer Sudoku is a puzzle where players fill a grid with numbers 1 to 9 so that each row, column, and 3x3 subgrid contains each number once, while also ensuring that the numbers in specified groups (cages) add up to given sums.

Backup & Restore

Now you can back up all your games (including folders and statistics), and app settings to a json file. And then restore it.
App can automatically back up your data every specified period of time (you need to enable this feature in settings)

Under the hood changes:

• Migrated to Compose Destinations navigation
• Migrated to Kotlin DSL with version catalogs
• Updated all dependencies
• VersionCode bumped from 7 to 20 (to sync with the app published on RuStore (that's a Russian thing, never mind))

Translation (Hosted Weblate)

Merged all strings and added many new languages. Thanks to everyone who helps to translate this app, love you 💖
