As an AI language model, I can help you with creating a simple game in HTML and JavaScript. Here's an example of a basic game implemented as a single HTML file, using pictograms and designed for smartphone operation:
Pictogram Game
🎯
Tap the pictogram to score points!
In this game, there is a target pictogram (represented by a dartboard emoji
🎯). When the pictogram is tapped/clicked on a smartphone, the player's score increases by one. The current score is displayed on the screen.
Please note that this is a very basic example, and you can modify and expand it to create a more engaging and complex game based on your specific requirements.
