Sure! Here's a simple brain game test that you can play on a smartphone using pictograms:
Brain Game Test
To play the game, simply copy the above code into a single HTML file (e.g., `brain_game_test.html`) and open it using a web browser on your smartphone. You'll see a grid of pictograms, and your task is to click on the pictograms in the correct order according to the shuffled sequence.
Once you click on a pictogram, it will either disappear if it's the correct one or show an error message if it's the wrong one. The game will reset automatically if you complete it or make a mistake.
Have fun testing your brain!
