"[Minecraft: Pocket Edition] has sold over 20 million copies (actually, over 21M)," said Bergensten, the game's lead developer. That means that sales have more than doubled in less than a year, and that the pace of that climb is increasing over time. The Pocket Edition debuted in October 2011 on Android and the following month on iOS, and it wasn't until the end of April 2013 that it reached 10 million copies sold. Earlier this month, sales of the game's Xbox 360 Edition surpassed 12 million copies.
"We're extremely grateful to all players for your dedication and creativity. Without that, Minecraft wouldn't be anywhere near as significant as it is today," said Owen Hill, chief word officer at Mojang, in a post on the studio's blog.
Three Minecraft developers — Bergensten, Johan Bernhardsson and Tommaso Checchi — are marking the milestone with a livestream set for Monday, April 14, in which they will answer questions submitted in this Reddit thread. Mojang said this past February that it plans to bring much bigger worlds to the Pocket Edition.
