As mentioned yesterday the Flappy Bird he has withdrawn from his creator and so if anyone wants to try it, he will not have the opportunity (at least from the official roads).
The game developer, Flappy Bird, Dong Nguyen, although he was earning $50.000 daily from the advertisements that appeared through the application, he preferred to withdraw it, to find his...peace.
But if you want to play the game and you haven't downloaded it to your device, there is a way and it's much more safes from downloading an application from an untrusted source.
You can play it through your browser via an HTML5 web page that has been uploaded to uralozden.com/flappy. At this address you can play the quite addictive game, not only with mobile devices, but also with computer your. (If the game doesn't show up with Firefox, try with Chrome)
