One of the first responses to the withdrawal of the game Flappy Birds from the iTunes App Store and Google Play was the release of multiple clone games, many of which were downloaded in huge numbers. But if you were a developer hoping to jump on the bandwagon, the moment has passed: both Google and Apple now appear to be actively rejecting Flappy Birds clones submitted to their stores.
Tech Crunch reports that several developers have had Flappy-branded games rejected. One rejection email spelled out the reason plainly:
We found your app name attempts to leverage a popular app.
Obviously you could still build Flash or HTML5 versions, but we'd suggest pursuing something original -- always a better strategy, even if there is a high likelihood your app will be copied if it's successful.
