Activision Blizzard's take on the popular auto-chess genre, Hearthstone Battlegrounds, has been live for only 24 hours but that hasn't stopped players from grinding to the top of the game's leaderboards. Currently, the title is only available to those who attended BlizzCon, purchased a BlizzCon Virtual Ticket, or pre-purchased the upcoming Dragons of Descent expansion card bundle. For those who haven't done any of the above, Battlegrounds is scheduled to go live on Tuesday, November 12 at 10 a.m. PDT.
