A Sudoku game in JavaScript
This was made using a RESTful Express.js API and a React front-end. To generate new boards, the API takes a difficulty string in the url parameter and reads a .txt file as a seed to the sudoku puzzle. The API then performs a series of transformations on the puzzle to produce a seemingly new puzzle.
The transformations done on the puzzle include:
- Mapping numbers (eg. all '1s' become '3s' and all '2s' become '8s')
- Rotating the board
- Shuffling rows and columns
- Check if you have Node.js installed. If you do not have node installed, follow the directions at https://nodejs.org/en
