"I just wanted to make an iPhone app. I thought it would be cool. And I wanted to see if I could do it," Robert said in a recent interview with Reuters. "I played games that were similar to it. I just took what I liked from different games, and, like, add my own stuff."
But Robert's "Bubble Ball," a puzzle and game of strategy that involves the principles of physics in moving a floating bubble from one point to another, is anything but a knock-off of other apps.
"He spent countless hours working on it, and the final product includes more than 4,000 lines of code. He sent it to the Apple app store on December 22. It appeared for download at the app store December 29," said his mother, Kari Nay.
Robert first began working on his invention in November.
"Bubble Ball" was downloaded 1 million times in its first two weeks of release from Apple's iTunes website and has since surpassed the 2-million mark, replacing "Angry Birds" as the site's most popular free app.
But Robert is developing a bit of an entrepreneurial spirit, too. He already is working on a new game that may include an "in-app" purchase option for additional game levels for 99 cents.
Asked about his advice to other young people, he hardly looks up while tapping away on his laptop.
"Go for your dreams and do what you want to do," he says.
