Flappy Bird was created in 2013 by Vietnamese developer Dong Nguyen and became a genuine global phenomenon in early 2014, briefly becoming the most downloaded free app on the App Store. Its extreme, almost punishing difficulty combined with its bare-minimum visual style made it a viral sensation, with players sharing their frustration (and rare successes) widely across social media at the height of its popularity.
In a widely reported move, Nguyen voluntarily removed the game from app stores in February 2014, citing that its addictive nature had become an issue he wasn't comfortable with, despite the game's massive commercial success — a decision that only added to its legendary status. It remains one of the most famous examples of a single-developer indie game achieving worldwide viral fame almost overnight.
The objective is brutally simple: get through as many pipes as possible without crashing, with your score being the number of gaps successfully passed — the challenge lies entirely in mastering the tight, unforgiving timing.
It's a genuine piece of viral gaming history, and its extreme difficulty is exactly what made it famous in the first place. If you enjoy this kind of reflex challenge, GBK Games also has Doodle Jump for another beloved one-input arcade classic.
