Sure! Here's an example of a simple chess game implemented as a single HTML file containing JavaScript code, enclosed in script tags:
This code creates a simple chessboard using HTML and CSS, and fills it with chess piece pictograms using JavaScript. You can add game logic to handle the movement of the pieces and implement the rules of chess as per your requirements.
Please note that this is a basic example and does not include any game logic or interactivity. It can be expanded upon to make a complete chess game for smartphone operation.
