As an AI language model, I can help you create a simple game that meets your requirements. Below is an example of a simple guessing game implemented as a single HTML file, using JavaScript and pictograms/icons for smartphone operation:
Save the above code into a single HTML file (e.g., `guess_pictogram.html`), and make sure to include your own pictogram images (`emozi_all/pictogram.png`, `emozi_hamuster.png`, etc.) in the same directory as the HTML file.
When you open the `guess_pictogram.html` file on a smartphone, you will see a guessing game where you need to identify the object depicted by each pictogram. Enter your guess in the provided input field and click the "Check" button to see if your guess is correct. Enjoy the game!
