This is a simple puzzle game containing a collection of 4x4 Sudoku puzzles. Sudoku puzzles are a common type of grid puzzle; information about them can be found on Wikipedia.
Use the mouse to drag tiles onto the grid so that each row, column, and 2x2 quadrant contains the numbers 1,2,3,4 in some order. Levels do not save when the game is quit.
This is a Zig project that natively calls raylib code (which is written in C). (More on dependencies below.)
Since the Zig compiler comes with its own build system and is also a C compiler, the project can be built and run with the command
zig build run
A release build can be created with the following command.
zig build -Doptimize=ReleaseFast
Building the project requires the compiler version to be 0.13.0 at minimum. The project has been tested with the Zig 0.13.0 compiler on Windows 11, available from the download page on ziglang.org. Compilation of the game on other operating systems has not been tested.
The project is written in Zig and uses the raylib library, specifically v5.0 (commit number c1ab645). We included the necessary source files from raylib directly in our project (under the deps/raylib_5_5 directory), but deleted unnecessary parts of the library (like its numerous examples).
Raylib is created by Ramon Santamaria (GitHub handle @raysan5) and is available on GitHub here. See the link above for Raylib's full license / copywrite details.
The entire development of this app (basically) was streamed on Twitch and recordings were uploaded to YouTube at:

The project was originally built with the Zig 0.11.0 compiler, and was updated to work with 0.13.0 of the compiler on 17 June 2024.
The project was originally built using Raylib 5, but was updated to use Raylib 5.5 on 31 Jan 2025.
