Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and smartphone-friendly pictograms. Please note that this is just a basic demonstration and can be further enhanced and customized as per your requirements.
In this example, there are three pictograms displayed as images on the web page. When the player clicks on any of the pictograms, the `checkAnswer` function is called with the corresponding answer as an argument (1 for pictogram1, 2 for pictogram2, etc.). The function then compares the selected answer with the correct answer (here, assumed to be pictogram2) and displays the result accordingly in the `result` div element.
Feel free to customize the pictograms, add more levels, and implement additional game mechanics based on your specific requirements.
