Nguyen took down Flappy Bird from the App Store and Google Play about a month ago, after receiving a torrent of online abuse for the game. In Flappy Bird, players would tap on the screen to keep a bird-like creature afloat as it traveled through a series of pipes.
According to research done by Pocket Gamer, nearly 250 games resembling Flappy Bird were released over a four-day period from Feb. 28 through March 3. That works out to an average of 60 each day and 2.5 per hour — or one every 24 minutes. Last month, The Guardian found that 95 Flappy Bird-like titles arrived on the App Store within a single day.
