Sure, here's a sample game in which you can control a circle using physics on a smartphone using JavaScript:

To play the game, you can open the above code in a web browser and you will see a canvas with a circle. You can control the circle's movement by touching and dragging on the canvas. The circle will bounce off the boundaries of the canvas. The game continuously updates the circle's position, giving it a physics-like behavior.
