Sure! Here's a prototype for a simple smartphone game using pictograms. Copy the code below into a single HTML file and open it in a web browser to play the game:
This game prototype will display four pictograms, and you need to select the correct one out of the options presented. The correct pictogram will be randomly chosen from the four displayed options each time you play. Clicking on an option will show an alert indicating whether your answer is correct or not.
Feel free to modify the pictogram list or add more functionality to the game according to your requirements.
