Certainly! Here's an example of a simple game where you can earn extra money by interacting with your smartphone using your body movements:
Money Earn Game
Move your smartphone with enough force to earn money!
Money earned: 0 $
In this game, the user can earn money by moving their smartphone with enough force as measured by the device's motion sensors. The accelerometer readings are used to detect the magnitude of the acceleration, and if it exceeds a certain threshold (in this case, 20), the player earns money. The amount of money earned is displayed on the screen.
Please note that this is a very basic example, and you can customize and enhance it further according to your preferences and requirements.
