Flappy Bird is a side-scrolling mobile game featuring 2D retro style graphics. The objective is to direct a flying bird, which moves continuously to the right, between each oncoming set of pipes without colliding with them, which otherwise ends the game. The bird briefly flaps upward each time the player taps the screen, and the player is scored on the number of pipe sets the bird successfully passes through. The game, which was released in May 24, 2013, was removed from both Apple's App Store and Google Play by its creator on February 10, 2014 due to the gameplay's addictive nature.
