Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags. The game is a guessing game where the player needs to guess a word based on a pictogram representation. It can be played on a smartphone.
Please note that this is a very basic example and can be further enhanced and customized as per your specific requirements.
To play the game:
1. Save the above code in a file with the extension ".html".
2. Open the file in a web browser on your smartphone.
3. The game will display a pictogram representation of a word.
4. Enter your guess in the prompt dialog that appears.
5. The game will notify you if your guess was correct or not.
6. Refresh the page to play again.
Note: In a more complete implementation, you could add additional features like keeping track of scores, displaying hints, or providing multiple levels of difficulty.
