What makes Google so economically successful?

In middle school, I had a friend whose father had worked for Google. Whenever I would be at their house he would be telling me all these crazy stories about the office that he had worked in. Chairs replaced with bouncy balls, scooters used to go to and fro, even napping orbs that the employees could use as their own personal “thinking time”. Everyday seemed like a vacation to him. Since hearing his stories, and growing up to gain a better understanding of the world and how corporations work, I am curious as to how such a successful business can exist with employees that are so carefree and seem to hardly do any work at all. Now, I know that some work has to be getting done within the Googleplex walls, but it seems that the founders and organizers of the Google workers value creativity, innovation, and relaxation to increase productivity in some way. How does Google create such a large revenue with such lax working areas and no blatant services that are being paid for?
