Angry Birds: Heikki
Description
Angry Birds: Heikki is a web browser based, Formula One themed version of the original Angry Birds game. It's subtitled Heikki as a result of Rovio's sponsorship deal with F1 driver Heikki Kovalainen.
Each level has the traditional Angry birds gameplay, but each of the twelve levels has been based on tracks featured on the 2012 F1 Calender. Players initially start with only the Silverstone (British GP) level unlocked, but subsequent levels are released on their respective grand prix weekends.
The game also has Heikki Powers, which serves as a score multiplier and can only be unlocked by going onto Kovalainen's Facebook page to obtain the unlock code and entered into the game. It can only be used once per level and a new code has to be obtained for it to be used again next level.
