Sure, I can provide you with a simple implementation of a Sudoku game using JavaScript, enclosed in script tags within a single HTML file. Please find the code below:
Sudoku Game
This implementation creates a simple Sudoku game with a pre-defined board. You can click on any cell of the Sudoku board to select it, and then type a number from 1 to 9 to enter it into the selected cell. Pressing the "Backspace" or "Delete" key will clear the selected cell.
Please note that this is a basic implementation and does not include the logic for solving or validating the Sudoku puzzle. It primarily focuses on the user interface and interaction. Feel free to enhance it further to meet your requirements.
