Over a 24-hour period beginning yesterday, approximately 293 new iOS games have been released into the App Store. 95 of those games are either Flappy Bird clones or heavily inspired by the original Flappy Bird title, according to data gathered by The Guardian.

Imitation is the greatest form of flappery.
