You've probably read about the ongoing kerfuffle happening around Dong Nguyen's Flappy Bird, a hideously addictive game that involves directing a chubby bird through a series of Mario-esque pipes. The game was making creator Dong Nguyen some $50,000 a day until he pulled it from Apple's App Store a month ago, on the basis that the game "was designed to play in a few minutes when you are relaxed… But it happened to become an addictive product. I think it has become a problem. To solve that problem, it’s best to take down Flappy Bird." 

'Flappy Bird' Creator Dong Nguyen Speaks Out

In the weeks since Nguyen pulled the game, there's been a flood of Flappy Bird-alikes, from straight-up clones like Flappy Wings and Splashy Fish to more, um, adventurous games like Tappy Bieber and Flappy Doge. Clearly, the public can't get enough of games that are both simple and brutally difficult. Still, Nguyen's creation and all its ilk have a way to go before they can rival the sheer addictiveness of this lot. By Tom Hawking
