As an AI text-based model, I can provide you with a sample game structure written in JavaScript, enclosed in script tags within a single HTML file. However, please note that the game logic and design will depend on your specific requirements and preferences. You can further customize and enhance the game based on your needs. Here's an example of a simple number guessing game created for smartphone operation using text prompts:
Please copy the code above and save it as an HTML file (e.g., `game.html`). When opened in a web browser, it will prompt the player to guess the target number, providing feedback on whether the guess was too high or too low. The game will continue until the player guesses the correct number and display the number of attempts made.
