DigitalDNA Games announced that its Minecraft-like sandbox survival game CastleMiner Z has surpassed 1 million units in sales, and is the first title in Microsoft's Xbox Live Indie Games catalog to reach the milestone.

DigitalDNA crested the million mark in just 10 months. Minecraft-inspired games are notably popular among XBLIG buyers, and the game's predecessor, CastleMiner, also remains a top title in terms of daily sales.
