The Angry Birds developer has launched a new upgraded version of Angry Birds, but this time it is a browser-based video game, named as 'Angry Birds Heikki'. The term Hikki refers to the F1 Racer from Finland called Heikki Kovalainen. I guess Rovio (Finland based Company) is trying to promote the people of Finland with the game.
The new Angry Birds Heikki is a racing-themed game where you get 12 tracks (or we can also call it levels) that keep getting unlocked as you go on clearing levels. This is time it is going to be more interesting because because you need to play the game with the birds moving on in the Formula 1 style.
