Which Finnish game designer created the Angry Birds franchise?

Finnish game designer Jaakko Iisalo created the Angry Birds franchise.

Iisalo’s original concept began with a sketch of stylized, wingless birds. The characters looked unusual even before they had a game, and that distinctive image helped inspire Rovio Entertainment to build a physics-based puzzle game around them. The first Angry Birds game launched for iOS on December 11, 2009.

A common mix-up is confusing Iisalo with Rovio executives and co-founders such as Mikael Hed, Niklas Hed, or Peter Vesterbacka. Those figures were important to Rovio’s business and the franchise’s growth, but Iisalo is credited as the designer who created the central Angry Birds concept.

The gameplay was influenced in part by Crush the Castle, another physics puzzle game. Players launched birds from a slingshot to destroy structures and defeat green pigs. The unexpected success of the original game transformed Angry Birds from a mobile title into a global franchise spanning sequels, television, merchandise, and films.
