A sudoku generator game hosted at https://dev-raj-kumar.github.io/Sudoku/
A player can select three different difficulty levels (easy, medium, hard) or random and sudoku would be generated.
Player could attempt to solve by filling the grids and also validate at the end. The app would check the submission and give the verdict.
If not able to solve then solution can be fetched.
The UI is designed using HTML div tag and the solution is provided using a backtracking algorithm.
