What gaming app pays real money?

I'm curious to know, is there a gaming app that actually pays out real money to its users? I've heard rumors of such apps, but I'm not sure if they're legitimate or just a scam. Can you provide some insight into whether these apps exist, how they work, and if there are any risks associated with using them? It would be great to hear from someone with experience in the field who can offer a well-informed answer.
