Sure! Here's a simple game implementing crazy randomness, rainbows, and bouncing balls using JavaScript and pictograms. You can save the following code into a single HTML file and open it in a web browser on your smartphone to play the game.

When you open this HTML file in a web browser on your smartphone, you will see multiple bouncing balls with random sizes and colors moving around the screen. The balls will bounce off the edges of the screen and change direction to create a dynamic and visually appealing effect. Enjoy playing with the crazy bouncing balls!
