In early 2014, the digital world was taken over by a surprisingly simple mobile game: Flappy Bird. Created by Nguyễn Hà Đông, an independent developer from Hanoi, Vietnam, the game challenged players to guide a small bird through a series of green pipes. Its graphics were basic and its concept straightforward, yet it became an overnight sensation, frustrating and delighting millions of players globally.

Flappy Bird was initially released in May 2013 but received little attention. Then, in January 2014, it experienced a sudden surge in popularity, climbing to the top of the free app charts. This organic growth was remarkable. The success was achieved with minimal marketing effort, relying on social media buzz and word-of-mouth from players sharing their high scores.

The sudden fame, however, brought immense pressure for Nguyễn Hà Đông. He was unprepared for the global spotlight and media attention. Feeling the game had become an addictive problem, he made a shocking decision. In February 2014, at its peak, he permanently removed Flappy Bird from app stores, stating he 'could not take this anymore.'

Despite its short life, Flappy Bird’s legacy continues. It proved that a single developer with a simple concept could capture the world’s attention. For many aspiring young programmers, especially in Vietnam, the story was a powerful source of inspiration. It demonstrated that a creative idea, regardless of its origin, has the potential for massive global impact in the modern digital age.
