TFA doesn't give the patent number, if you want to know you'll have to dig up whatever they've filed with the courts. I'd start looking in EDT; I'm just guessing, but it's where all the trolls file for quick, predictable payouts.
All the article says is that the patent allegedly covers buying new levels from within the game. So the patent is probably some generic nonsense about a method of having an ordinary computer do ordinary things. But nobody prior to them patented or mentioned doing those particular ordinary things on a computer, so it's not considered legally obvious, no matter how much it makes us want to bang our heads on a wall.
EDIT: I should mention that we won't know if they infringed at all (or whether Lodsys has a valid patent) unless it goes all the way through the system. Depending on what's being demanded, they may find it cheaper to settle, even if the patent is garbage and they may do so as a pure business decision.
