Sure, I can help you create a simple game using JavaScript in a single HTML file. Here's an example of a game where the player needs to match pictograms:
In this game, we have an array of pictogram image URLs stored in the `pictograms` variable. The images are shuffled randomly, and a grid of pictogram tiles is created using a loop.
Each tile has a click event listener that checks if it matches the previously selected tile. If the clicked tile matches, both tiles remain matched. Otherwise, they are temporarily highlighted and then unselected.
The `shuffle` function is used to randomize the order of tiles in the grid.
You can save this code into an HTML file and open it in a web browser on your smartphone to play the game. The tiles will be displayed in a 2x2 grid, and you can tap on them to find matching pairs of pictograms.
