The game is based on a now defunct iPad game called "Casey's Contraptions" from game makers Snappy Touch and Mystery Coconut Games, which Rovio bought and tinkered with to create Amazing Alex.
"The gameplay is a perfect fit in our arsenal with its approachable, fun and highly addictive take on the physics puzzler genre," Rovio's vice president of franchise development Ville Heijari told the website Gamasutra in May when the new game was announced.
Amazing Alex comes with 100 levels, but players are also invited to design new levels using 35 interactive objects and share them either among friends or with the entire "Amazing Alex" playing public.
The big question, of course, is whether Amazing Alex has the kind of legs that Angry Birds has. In May of 2012, Rovio said that various versions of the addictive Angry Birds game had been downloaded more than 1 billion times.
