Now the company is aiming to repeat the trick with Angry Birds Transformers.
It's Rovio's latest partnership with Hasbro, and will include a mobile game, licensed merchandise and a range of toys later in 2014.
Details of the game are being kept under wraps, although Hasbro has confirmed that it will focus on a battle of "Autobirds and Deceptihogs across multiple formats and entertainment platforms".
Initial artwork for the game – shown above – confirms that it will blend existing characters from the Angry Birds and Transformers universes, following on from the Angry Birds Star Wars games.
"This mash-up is going to appeal to those who grew up with the brand in the 80s, as well as fans of the brand today," said Blanca Juti, Rovio's chief marketing officer, in a statement.
A key part of the two companies' deal is the line of Telepods toys that will be sold alongside the smartphone and tablet game, with players able to scan in toys to have those characters appear in the game.
In May, Rovio said that players of Angry Birds Star Wars II – released in September 2013 – had been scanned in by players more than 30m times.
Hasbro sold more than 1m Telepods in the first month after the game's release, and has since launched a separate line for the Angry Birds Go kart-racing game.
Angry Birds Transformers will be joined by Angry Birds Stella – a sub-brand aimed more at women and girls – when it launches later in 2014. Rovio has also just released Angry Birds Epic, which takes its franchise into new genre territory: roleplaying games (RPGs).
