Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
⚽️ 🎾 🏀
This example game displays three pictograms (⚽️, 🎾, 🏀) on the screen. The user needs to click on the correct pictogram to win the game. When the user clicks on a pictogram, an alert will show indicating if they guessed correctly or not. After each guess, a new target pictogram will be displayed for the user to guess again.
