Sure! Here's an example of a simple HTML game that can be played on a smartphone using pictograms:
Pictogram Game
This game creates a grid of pictograms and allows the player to click on each pictogram to reveal it. The pictograms are shuffled randomly each time the game is loaded.
You can copy the above code into an HTML file and open it in a web browser to play the game on your smartphone. Just tap on the pictograms to reveal them!
Note: The game can be customized by adding more pictograms to the `pictograms` array or modifying the styling of the game board and pictograms using CSS.
