In my latest delve into the world of online gaming, I discovered how free online games actually turn a profit. It turns out, they primarily make money through in-app purchases and advertising. Players often have the option to buy virtual goods or additional features, which provides a steady income for developers. On top of this, these games often display ads, which generate revenue each time they are viewed or clicked on. So, while we're enjoying these games for free, our engagements are indirectly funding their operations.
