A free game–"Bubble Ball"–invented by 14-year-old Robert Nay, "has been downloaded more than 2 million times. Last week, it nabbed the #1 spot on the list of free games in Apple’s iTunes store, knocking the ever-popular "Angry Birds" game to #2," reports ABC News.
According to the article, "For more than a month, Robert spent a couple of hours each day on the game, ultimately writing more than 4,000 lines of computer code, his mother [Kari] said. Kari Nay said she helped him design some of the puzzles in the game, but he came up with the concept and did everything else on his own."
The story contines, "According to its App store description ‘Bubble Ball’ is a ‘fun, new physics puzzle game, where you will test your ingenuity and thinking skills to get the bubble to the goal.’
