Sure! Here's an example of a memory card game implemented as a single HTML file, using JavaScript and enclosed in script tags:
Memory Card Game
This implementation creates a memory card game with pictograms represented by emojis. It randomly shuffles the cards and allows you to flip two cards at a time. If the flipped cards match, they stay flipped, and if they don't, they are flipped back. The game continues until all the cards are matched, at which point a congratulatory message is displayed.
To play the game, you can save the above code as a `.html` file and open it in a web browser (preferably on a smartphone for a better user experience). Have fun playing the game!
