Blizzard has announced iPhone and Android versions of its collectible card game Hearthstone.
Both versions are in development at the company and will be out "probably" in the first half of 2014, Blizzard said at BlizzCon.
Meanwhile, the PC version goes into open beta next month, or, perhaps, January 2014, Blizzard said. An iPad version is also in the works.
Blizzard is working on golden heroes, which will be unlocked in a new ranked play mode. These will be fully animated, just as golden minions are.
Blizzard's goal with the new ranked play mode is to make constructed as much fun as the Arena mode, currently favoured among closed beta players.
