Sure! Here's a simple game that you can play on a smartphone using pictograms:
To play the game, save the above code as an HTML file (e.g. "game.html") and open it in a web browser on your smartphone. You will see a randomly chosen pictogram displayed on the screen. Your goal is to guess the corresponding color of the pictogram by tapping on it. If you tap on the correct color, you will receive a "Congratulations!" message. If you tap on the wrong color, you will receive an "Oops! Try again!" message. Enjoy the game!
