How to install

• if you are using nixos, and binary does not run, check out this

Android

1. Grab latest released .apk.
2. Launch it on your phone.

Little tip for Android users. For all of my open-source apps, I use app manager Obtainium. Because this project is currently only on GitHub, you can't receive updates automatically if you only install .apk. But Obtainium can help you with this.

How to build

1. If there is no extnesion in bin folder, grab (or build yourself) SudokuLib binding for your platform and put it into bin folder.
2. Export project in Godot

Plans

• Write better building documentation (build with godot-headless, for example)
• Better generating engine with options.
• Better file manager, especially for Android. There are PR to Godot, adding support for native file picker, but no one knows when it will be done and merged : (. And, as far as I know, there are no Android native file piker openers for Godot now.
• Add colors to the grid.
• Multiple selection.
• Scanning Sudoku from image.
• Parsing Sudoku from websites.
• Built-in wiki with Sudoku methods description and app in general.
• Statistics for solved puzzles.
• Replay of solving.
• Undo and redo.
• New kinds of puzzles (like Killer Sudoku, and many others)

How you can help

If you know Java, you can write Android plugin that can open Android's native file manager.

If you are good at designing in Godot, you can help improve app design. Gudoku lacks good UI...
