Sure, here's a simple game implemented as a single HTML file using JavaScript:
This simple game selects three random items from a predefined list of pictograms (represented by emojis) and checks if all three items are the same. If they are, it displays a winning message; otherwise, it displays a losing message in the browser's console.
You can play the game by opening the HTML file in a browser on your smartphone. Each time you refresh the page, a new random game will be played.
