Are there apps you can win real money?

Are there indeed any mobile applications available that offer users the chance to win real money? I'm curious about the legitimacy and security of such platforms, as well as the various games or activities one might engage in to potentially earn rewards. Furthermore, I'm interested in knowing if there are any specific regulations or restrictions surrounding these types of apps, particularly in terms of age limitations and geographical availability. Can you provide any insights or recommendations for those looking to explore this aspect of mobile entertainment?
