Sure, here's a simple game implemented as a single HTML file using JavaScript:
In this game, pictograms (emoji symbols) are randomly shuffled and displayed on the game board. The objective is to click on the pictogram that matches the one displayed at the top. If you click on the correct pictogram, it will be removed from the board. The game ends when all pictograms are correctly clicked.
Please note that this is a very basic example, and you can modify and enhance it further according to your requirements.
