Sure! I can help you create a simple game using JavaScript that can be played on a smartphone and implemented as a single HTML file. Here's an example:
In this game, there is an array of pictograms represented by emojis. The `shuffle` function is used to randomize the order of the pictograms. The `startGame` function creates a game container and appends the shuffled pictograms inside it. The game is triggered by calling the `startGame` function.
When you open this HTML file on a smartphone, it will display the shuffled pictograms as a game. Each time you refresh the page, the sequence of pictograms will change due to shuffling.
Feel free to modify and enhance this code according to your needs.
