Sure! Here's a sample code for a simple game using JavaScript and pictograms, enclosed in script tags within a single HTML file. This game can be played on a smartphone:
In this game, when the "Start Game" button is clicked, a random pictogram from the given array will be displayed. The player can try to guess what the pictogram represents. The pictograms array can be expanded with more pictograms as desired.
Please note that this is a basic implementation and can be further enhanced to include additional features or gameplay mechanics based on your requirements.
