Piracy is a big problem for premium iPhone and iPad games — much more than you realize

Yes, iOS games are being pirated.

For example, 60 percent of Monument Valley installs on iPhone and iPad were not paid for. I’m not a newcomer to the game business, so I know that most of those pirated downloads wouldn’t translate to sales, if somehow we could stop piracy. And for Monument Valley, the problem is even worse on Android, with 95 percent of the downloads there being “illegitimate.”
