Hearthstone timeline

This page aims to chart the major events of Hearthstone, from its initial conception to the introduction of the latest feature.

For a timeline of Hearthstone's meta history, see Meta.

June 5
 * With recently unveiled planned class cards for Curse of Naxxramas showing a tendency not to state when certain effects are random, Ben Brode releases a blog sharing the team's approach to the word 'random', explaining that by not explicitly stating the randomness of effects in 'hidden' game areas, groundwork can be laid for future shortening of text. Despite this explanation, continued feedback from players finding the new cards' descriptions confusing and ambiguous eventually lead the team to alter their stance, with an announcement a few days later that the word 'random' will be added to the cards' text.

June 24
 * Several claimed screenshots of Curse of Naxxramas are leaked, showing numerous game details and three unannounced legendary cards. Blizzard neither confirm nor deny the details revealed in the screenshots. However, the adventure's official release nearly a month later confirms the screenshots as genuine.

 * Blizzard announces that more than 20 million players have now played Hearthstone.

September 18
 * For the first time, player distribution across Ranked play rankings is released, in an announcement blog titled You're Better Than You Think!

October 30
 * Just over a week ahead of BlizzCon, press and members of the Hearthstone community begin receiving special "blueprints" for various mechanical minions in the game, sparking speculation among players. The blueprints are accompanied by a note which reads "Making plans for BlizzCon - I hope you like my invention!", the latter line referencing the summoning quote of the Novice Engineer, reinforcing the mechanical theme. Designs include the Harvest Golem, Demolisher, Poultryizer and Repair Bot.
 * Blizzard announce that they have recently banned a number of accounts found to be engaging in win-trading. Following the recent mass-ban of botting accounts, the announcement is used to further emphases Blizzard's commitment to "fair play" in Hearthstone, and encourage players to abide by the rules.

That’s where you come in! Cast your vote on what flavor text makes it into Hearthstone for the Legendary card, C’Thun!"
