Google has designed and very well hidden small mini-game inside on the official site Android.com The game is very nice, seeing our little green robot trowing snowballs against a snowman. This is not the first Easter Egg on the site but is currently the most elaborate.
To access it you will not have to do is move the mouse over the image of the android next to the words "Terms of Service - Privacy Policy" and click to bring up further down the mini-game and start the challenge.
The difficulty is regulated by the flag that indicates which way the wind is blowing, how aggressively the three lives left to be hit by snowballs.
Have fun and all congratulations to Google, which gives us from time to time little fun surprises.
