Sure, I understand that you want a game implemented as a single HTML file using JavaScript and enclosed in script tags. Here's an example of a simple game that you can play on a smartphone using pictograms:
In the above implementation, the game randomly shuffles the pictograms array and displays them on the screen. When you refresh the page, the pictograms will be rearranged, offering a different game each time.
Note: This is a basic example just to give you an idea. You can enhance the game logic or add more features as per your requirements.
