As an AI language model, I can provide you with a sample outline for a simple game implemented as a single HTML file using JavaScript. Since you mentioned smartphone operation and the use of pictograms, we can create a basic number matching game using emojis. Please feel free to modify and expand upon this template as per your requirements:
Number Matching Game
Tap the matching emojis!
Copy the provided code and save it with a .html extension. When you open the HTML file in a web browser or a smartphone browser, you will see a simple number matching game using emojis. To play the game, tap on the emojis to reveal their values. Match all the pairs to win the game.
Please note that this is just a basic example to demonstrate how the game structure could be implemented. You can customize and enhance the game further based on your preferences, such as adding levels, time limits, or additional features.
