1. Install Rust and Cargo: https://www.rust-lang.org/tools/install
2. Clone the repo and build the project:

git clone https://github.com/pavlvolk/SudokuImageGeneration.git
cd SudokuImageGeneration/Backend
cargo build

Start the Server first:

cargo run

You'll have to leave that terminal window open and use another one for the website. In the new terminal window:

cd SudokuImageGeneration/Frontend
xdg-open index.html

Now you can use the website to its full capability!

Options include:

• Grid size (4x4, 6x6, 9x9)
• Sudoku Generator or Sudoku Solver mode
• Background Image (You can upload or remove a background image to aid with your drawing)
• You can either only mark cells or also add specific numbers at certain places
• The difficulty and number of marked cells for each sudoku will be displayed
• If a unique sudoku was found you can download the partial sudoku or the solution

• This project uses cadical for SAT solving. We gratefully acknowledge the developers of cadical-rs for providing this library.

• It also uses the sudoku-generator by stunmuffin.
