What was the first spin-off game in the Angry Birds series?

The first spin-off game in the Angry Birds series was Bad Piggies. Released in September 2012, it shifted the focus from launching birds at structures to constructing vehicles for the pigs.

Angry Birds Seasons was an early successor, not the first spin-off. It began as Angry Birds Halloween in October 2010 and later became a holiday-themed version of the original game. Angry Birds Rio, Angry Birds Space, and Angry Birds Star Wars were also later entries or crossover titles.

Bad Piggies stars the green pigs from the original Angry Birds game. Players assemble vehicles from available parts and use them to transport pigs across obstacle-filled stages. The construction system differs substantially from the original game’s slingshot mechanics.

The game was developed and published by Rovio Entertainment. Its release established Bad Piggies as a distinct spin-off rather than simply another themed installment of Angry Birds.
