How do free online games earn money?

Well buckle up folks, because we're about to dive headfirst into the wild, wacky, and - let's face it - slightly perplexing world of free online games and how they manage to make moolah! It's like a magician pulling coins out of thin air, or finding loose change in your couch! They get their dough mainly from two sources: in-game purchases and advertising. You see, players can buy virtual items, or level up faster, by spending real money - kind of like a shortcut to gaming glory! And then there's the ads, oh the ads! They're like those uninvited party guests that keep popping up, but hey, they bring in the bucks!
