If you look at the iOS App Store, all of these "clones" are in the top 15:<p>1. Ironpants<p>2. Fly Birdie<p>5. Flappy Bee<p>15. Flappy Plane<p>I'm sure more will come, but it's still crazy to me that there are 4 apps that all have essentially the same mechanics. It also makes me wonder how long the app store will ride out helicopter style games.<p>I jokingly said to my roommates tonight, "we should just make a mini putt clone for iOS." Seems like I never have any idea anymore of which old arcade or flash based hit will pop up on my phone with a fresh look as the #1 app.
