Sure! Here's a single HTML file game that turns an apple into a unicorn when clicked 10 times. If the apple is clicked more than 10 times, a monster will appear and end the game. The game is designed for smartphone operation and uses pictograms.

When you open this HTML file in a web browser on your smartphone, you'll see an apple emoji (
🍎). Tapping on the apple will increment the click count by one. If you tap it 10 times, it will change to a unicorn emoji (
🦄). If you tap it more than 10 times, a monster emoji (
👹) will appear while the background changes to black and the text color changes to white. After 3 seconds, the game will automatically reload to play again.
Keep in mind that this is a basic implementation, and you can customize the game further as per your preferences.
