Flappy Bird reminds me of the old retro games that I used to play in childhood. It's very addictive game I have played in a while now and not actually on my phone, but on web browser.

Flappy Bird, which was originally built for iOS and Android by the developer is now available online as a flash game. The flash version of the game is same as the phone version but it isn’t created by the same developer. The online version features the original gameplay with option to jump using the mouse click or the space button.

You can play this game here on the Kongregate site.

If you want to play the game offline, you can do so by installing BlueStacks. BlueStacks is an Android emulator for Mac as well Windows. After setting up the emulator, you can download Flappy Bird from the Google Play Store and play anytime when you want.
