[HELP] Making money with Android games

Hello, I am a game designer. I made a couple of cool games, and one I sold for 500$ (I sold the licence to it). I am not sure if I can leave links here so you can search it on google play, it's called CrazyBox. Does anyone know any good way how to promote these games? Only way I know now how to make money off of them is to sell the licence, but that is really short term... If you want to check rest of my games I can send them to you by private message
