It's been almost a month since Dong Nguyen removed Flappy Bird from the App Store, but Apple's digital marketplace continues to be flooded with low-rent rip-offs of Nguyen's smash hit.

In an investigation into the last 300 Flappy clones to hit Apple's App Store, Pocket Gamer has discovered that on average 60 clones are added every day (about 69 on February 28th, 48 on March 1st, 75 on March 2nd, and 49 on March 3rd).

On average, that means 2.5 clones are added an hour - or one every 24 minutes.

Because of Apple's uneven release schedule, where apps are only added between the hours of 15:00 and 08:00 UTC, you couldn't set your watch by it. On some days, 14 Flappy games can be added in the space of one hour, for example.

Our definition of a Flappy Bird clone, by the way, is any game in which you guide some character through an obstacle course of pipes (or similar objects) hanging from the ceiling and sticking out of the ground.

That character could be a bird, a fish, an eagle, a super goat, Nyan Cat, Justin Bieber, Miley Cyrus, Bear Grylls on a jet pack, Flappy Bird inventor Dong Nguyen, the floating head of Kanye West, or the chief minister of the state of Gujarat, Narendra Modi.

These copycat games have names like Senor Pez, Funny Chicken - Bird Adventure, Trappy Bird, Flappy Fish 2D, Flappy Endless Car 3D! Flappy You: Fly Your Face Free, Nerdtle: The Flappy Birdtle, and Bird Adventure - 1 Touch Flying Bird.
