As agreed with Óscar García Amor the author of the current Open Sudoku, I'm the new maintainer of that code and the Open Sudoku 2 was moved to Open Sudoku project. In practice it was more like overwriting old code because practically all the java code was rewritten in Kotlin, there were plenty of changes here and there and new functionalities.
To get the newest version please to the Open Sudoku repo. Backward compatibility with the previous Open Sudoku is now verified so that users of old Open Sudoku should not loose their data by updating to the new version.
Open Sudoku 2 is an open-source Sudoku game based on the Open Sudoku project. Open Sudoku 2 has been rewritten in the Kotlin programming language with lots of improvements, fixes and reimplementation. It is up to date with the current Android coding standards. New functionalities as well as improvements for the already existing ones are there.
It's designed to be controlled both by finger and keyboard. It's preloaded with 90 puzzles in 3 difficulty levels. More puzzles can be downloaded from the web, and it also allows you to enter your own puzzles.
The application is currently in the testing stage on Google Play. To join testers and get automatic updates please follow this Open Sudoku 2 Google Group link and click on the "Ask to join group" button. Once approved you'll get access and see the Play Store link you can use for app installation and updates. The link is only accessible for the group members.
The app binary is at the moment accessible only for testers until it passes Google testing requirements (20 testers opted in for at least 14 days), but you can always build your own binary from the sources available in this repository.
