Last April, Dong Nguyen, a quiet 28-year-old who lived with his parents in Hanoi, Vietnam, and had a day job programming location devices for taxis, spent a holiday weekend making a mobile game. He wanted it to be simple but challenging, in the spirit of the Nintendo games he grew up playing. The object was to fly a bug-eyed, big-lipped, bloated bird between a series of green vertical pipes. The quicker a player tapped the screen, the higher the bird would flap. He called it Flappy Bird.
The game went live on the iOS App Store on May 24th. Instead of charging for Flappy Bird, Nguyen made it available for free, and hoped to get a few hundred dollars a month from in-game ads.
