Sure! Below is an example of a simple Pokémon game implemented as a single HTML file using JavaScript. You can play it by clicking on the pokeball to throw it and try to catch as many Pokémon as possible. The game ends after 10 attempts. Note that this is a simplified implementation for demonstration purposes, and you can customize and add more features to make it more engaging.
●
To play the game:
1. Copy the entire code into a new HTML file (e.g., `pokemon.html`).
2. Open the HTML file using a web browser (preferably a smartphone browser for the requested smartphone operation experience).
3. Click on the pokeball icon to throw it and try to catch the Pokémon.
4. After 10 attempts, the game will end, and you will be shown your final score.
Note: Since this is a simple game, the caught/escaped Pokémon is represented by a pop-up alert. You can modify it to display a visual element or add more game mechanics and features based on your requirements and preferences.
