Sure! Here's an example of a game implemented as a single HTML file using JavaScript and pictograms. The game is played on a 120 square chessboard.
This example creates a 120 square chessboard represented by div elements with the class "square". Each square is clickable, and when a player clicks on an empty square, a black rook (♖) will be placed on the selected square, and the AI (represented by a white rook - ♜) will make a random move on an empty square.
Note: This is just a basic example to illustrate how a game on a 120 square chessboard could be implemented. The AI logic and gameplay mechanics can be expanded or modified according to your specific requirements.
