Sure! I can assist you in creating a country game using JavaScript within a single HTML file. The game will be designed for smartphone operation and will feature pictograms. Here's an example implementation using various countries as options:
In this example, an array called `countries` is defined with five different countries represented by pictograms. The game will display each country one by one and present corresponding buttons for the user to select. If the user chooses the correct country, their score will increase. Once all countries have been displayed, the final score will be shown.
