Sure, here's an example of a simple virtual circus game implemented as a single HTML file with JavaScript:
Coloring Virtual Circus
This code will create a 10x10 grid of circus tiles on the canvas. Each tile, represented by a div element with the class name "tile", can be clicked to randomly change its background color. The available colors for the tiles are defined in the `colors` array.
You can open the HTML file in any web browser on your smartphone to play the game. Simply click on the circus tiles to color them randomly using the available pictogram colors.
