As an AI text-based model, I can provide you with a sample game implementation using JavaScript within a single HTML file. However, note that this is a text-based game and doesn't specifically incorporate pictograms for smartphone operation.
In this game, you start with 6 rounds of ammunition (playerAmmo) and a score of 0 (playerScore). You can shoot by invoking the `shoot()` function, and it randomly determines whether you hit or miss the chicken target. Each successful hit awards you 10 points.
Additionally, there is a `reload()` function that replenishes your ammunition to the maximum of 6 rounds. The game messages and score are logged to the console for demonstration purposes.
Feel free to build upon this base and implement additional gameplay logic or enhance the user interface as needed.
