Fascinating look at the second year of Monument Valley – particularly after a cameo on House of Cards and a promotion on the App Store:

Underwood turned out to be a great pitch man, one of several reasons why Monument Valley was actually more successful in its second year of existence, compared to the first. According to developer Ustwo, the game has been downloaded more than 26 million times to date, and more than 23 million of those downloads came in the second year after it released. “We’ve actually had to spend a lot of time maintaining the game,” says Dan Gray, head of studio at Ustwo Games, “and finding new opportunities for people to find out about it.”

For the second year in a row, Ustwo has released a detailed infographic that showcases how well the game performed on various platforms. While year one showed that it was still possible for a premium game to make money on mobile, year two shows just how huge of an audience you can reach by offering your game for free — the biggest reason behind _Monument Valley_’s enduring success wasn’t a fictional US president, it was the lack of a price tag.

The difference in downloads between the first and second year on iOS is remarkable, but even more impressive is the performance in China.
