Monument Valley developer Ustwo revealed that only five percent of the game's installs on Android are "paid for." It divulged "interesting data" about the game in recent tweets, clarifying that a "small number" of the other 95 percent of installs were legitimate. Additionally, the data does not account for the one promotional day in which Monument Valley was free on the Amazon Store. By comparison, Ustwo said that 40 percent of the installs for the game on iOS were paid for.
Piracy isn't a new problem for the Android platform, as indicated by games such as Lucky Frame's Gentlemen!. The Edinburgh, Scotland-based independent developer announced in August 2013 that just 144 of the 50,000 downloads for Gentlemen! on Android were legitimate. Ustwo first launched Monument Valley on iOS in April 2014 before it arrived on Android one month later. The game reached one million copies sold in July after having recouped its development costs after one week on the App Store. It received eight new levels on iOS in November and earned a year-end award from Apple last month.
