Sure! Here's an example of a simple clicker game implemented as a single HTML file using JavaScript. The game allows you to click on a cookie to earn points, and it also displays a leaderboard with the number of clicks made by the player. Pictograms are used for visual representation.

To use the code, create a new HTML file and paste the above code inside it. Save the file with a `.html` extension (e.g., `cookie_clicker.html`). Then, you can open the file in a web browser (preferably on a smartphone) to play the game. Clicking on the cookie image will increase your score, and the leaderboard will show the rank of players based on the number of clicks they have made.
