No more “Flappy” games, please.

That appears to be the request of both Apple and Google, which, as reported by TechCrunch, have been rejecting developer submissions for games with “Flappy” in their titles.

According to Apple at least, such games have been denied availability because their names attempt to “leverage a popular app.”

That “popular app” is, of course, none other than Flappy Bird. Indeed, the one-tap bird-flying game has become so popular — so popular that its sleeper success proved too much for creator Dong Nguyen, prompting him to remove it from the App Store and the Google Play Store last week.

But one popular game’s removal is quite a few other games’ chance to cash in. Following Flappy Bird’s withdrawal, a number of similarly named clones have emerged. These include, but are certainly not limited to: Fly Birdie – Flappy Bird Flyer, Flying Flappy Unicorn Bird, Splashy Fish – The Adventure of a Flappy Tiny Bird Fish, and City Bird – Flappy Flyer — the latter two of which are currently the top two free games in the App Store.

“Unfortunately, if Apple was trying to prevent these ‘Flappy Birds’ clones from taking over the top ranks in the App Store, they’re too late,” TechCrunch notes. “The fair thing to do is force everyone to rename their ‘flappy’ games, and/or pull ‘flappy’ from their keywords.”

As it turns out, the Flappy Bird clone formerly called Flappy Bee now goes by the name of Jumpy Bee. One down, lots more “Flappy” games to go.
