Are there any games that actually pay real money? Yes, there are many apps that pay you real money to play games, including apps that use the Skillz competitive gaming platform. If you're wondering how to make money on the side, games that use the Skillz platform could be a good place to get started.
None of them. As you've discovered, NOBODY is paying you big money just to play games or watch videos. Feel free to play those games if you find them fun (some people do) but do not play them expecting to ever get paid.
