iPhones Flappy Bird Game on Ebay are a topic of interest for lots of online gamers.

Ever since Dong Nguyen, the Vietnamese creator of Flappy Bird decided to drop his game from the app stores, the demand for the Flappy Game has in high demand.

So much so that developers are flooding Apple and Google app stores with clones of iPhone Flappy Bird Game on Ebay. That's when Google and Apple decided to pull the switch on clones. Both the firms said that clones were building a business around the original Flappy Bird and this would be classified as scam.

Google, in particular, does not tolerate spam.

Since this scenario, more and more used electronic retailers are listing second hand iPhones with Flappy Bird Games installed. You would not believe it but these second hand phones with Flappy Bird are going for thousands of dollars.

After the second hand iPhones with Flappy Bird Games became a trend on eBay, the site decided to end the listings since it was violating the website's policy.

Now another website Upgrade Swap is advertizing to pay smartphone users more than their money's worth if they possessed preinstalled Flappy Bird Games on their phones.

Of course, an iPhone might fetch a lot more, but be prepared to get an extra $20 bucks for a lackluster device that just has the Flappy Bird installed on it.

While Upgrade Swap's marketing ploy may not translate to rapid sales of the pre-installed game phones, it still points to how popular the game is despite its removal from app stores across the world.

Most likely, the phones collected by Upgrade Swap will be factory reset, which might mean the game cannot played on these phones.

In an interview with Forbes, Don Nguyeng said he was sorry that he disappointed his fans by pulling the plug on the popular game. Meanwhile, clones galore continue to infuse the market, despite curbs by Google and Apple.
