Sure! Here's an example of a matching game implemented as a single HTML file using JavaScript:
Matching Game
To play the game, simply open the HTML file in a web browser, and you should see the matching game interface. The game starts automatically, and you can click on the cards to flip them. The objective is to find all the matching pairs. Once all pairs are found, an alert message will appear, indicating that you won the game.
Please note that this is a basic example just to showcase the game mechanics, and you can customize the styling, symbols, or game logic as per your requirements.
