Rovio appears to have done it again. Early this morning, around 12AM PT, Rovio launched their new game Bad Piggies, a spin-off of the oh-so-popular Angry Birds series. This new game features many similar characters from the older Angry Birds series, but focuses on the pigs' point of view.

Players build vehicle-style contraptions to get through the map, as opposed to flinging, well, angry birds. Just three hours after its launch, Ville Heijari tweeted that the game had rocketed to the top spot in iTunes for the US. This is an incredible rate of adoption, considering that most of the US should have been sleeping at launch.

Comparing the success of Bad Piggies to Angry Birds Space is a bit difficult. There isn't an exact time frame available for how long it took Angry Birds Space to hit number one. Remember that Angry Birds Space achieved 10 million downloads in 10 days and 50 million downloads in 35 days, both impressive feats. Let's see if Bad Piggies can beat it.
