Flappy Bird is a popular mobile game created by Vietnamese developer Dong Nguyen. Released in 2013, it quickly gained fame for its simple yet challenging gameplay, where players control a bird that must navigate through a series of pipes by tapping the screen to flap its wings. The game's retro graphics and addictive nature contributed to its viral success, leading to millions of downloads. Despite its popularity, Dong Nguyen removed the game from app stores in 2014, citing concerns over its addictive qualities. Nevertheless, Flappy Bird remains a significant part of mobile gaming history.
