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#History.

2008[edit | edit source]

June or earlier

  • Team 5 is created, and development of Hearthstone begins.[1] Ben Brode states that his first records are from June 2008, but that "full-on development didn't start for a while after that".[2][3]

2009[edit | edit source]

Deadlines for StarCraft II cause all of Team 5 except Eric Dodds and Ben Brode to be reassigned to that game for around a year. Dodds and Brode begin prototyping, rapidly iterating through myriad designs.[4]

2010[edit | edit source]

Dodds and Brode produce the first working version of Hearthstone, using Flash.[4] The rest of Team 5 return from working on StarCraft II to begin developing Hearthstone from this basic prototype into the full game.[4]

2012[edit | edit source]

Following mixed responses from within the company to Hearthstone's initial announcement, in December 2012 the game achieves "broad exposure" across Blizzard, with a substantial portion of employees playing Hearthstone, and beginning to get "really excited" for the game.[1]

2013[edit | edit source]

April 11

April 17

April 26

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.
Curse of Naxxramas - where the fun never dies!

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.

July 22

August 15

  • Blizzard release an official statement regarding botting in Hearthstone, stating that "A fun, fair, and competitive environment is at the very heart of the Hearthstone experience", and that use of botting software is against the game's Terms of Use. The announcement comes as bots rise to prominence in the game for the first time.[8]
September 2014 saw Hearthstone reach the 20 million player mark

September 15

  • Blizzard announces that more than 20 million players have now played Hearthstone.[9]

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! The title refers to widespread underestimation of player ranking in Ranked mode, due to the pattern of player distribution, with the top 50% of ranks held by around the top 5% of players.

October 21

  • The first Hearthstone infographic is released, revealing statistics including that the game has so far been played for 2 billion hours in total; that 69 million Hounds have been unleashed; and that the longest ever Play mode win streak was 24 games.[10]

October 27

  • Blizzard announce the temporary banning of several thousand accounts that were associated with the use of third-party botting software. Furthermore, it is announced that any accounts found using botting software from this point on will be permanently banned without warning.[11] It would later be stated that over 10,000 accounts were banned from the game for botting.[12]
"I hope you like my invention!"

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.[13] 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.[13] 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.[14] 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.
"Goblins and gnomes... goblins and gnomes!"

November 7

November 20

  • The Goblins vs Gnomes DeviantART challenge is announced. The challenge is to create an original artwork based on Goblins vs Gnomes, and features a total prize pool of $8,500, as well as various other rewards.[15]

2015[edit | edit source]

In March an animated elemental was added to the official site

January 29

  • Patch 2.1.0.7628 sees a minor adjustment to the China, Korea and Taiwan clients which cause the player 'Hello' emotes to instead say 'Happy New Year'. While trivial, this mark's the game's first seasonal customisation.

February 26

  • Information gathered by fan sites from an upcoming patch leads to speculation regarding the game's next adventure. With data referring to Molten Core, Ragnaros and 'brm', Blackrock Mountain is speculated to be the theme. The patch comes roughly a week before PAX East, where the new game's content is widely expected to be announced.

Early March

  • An animated elemental is added to the official site, just above the site navigation bar (see right). In addition, the sample cards on display are changed to Leeroy Jenkins, Twilight Drake, Core Hound, Dark Iron Dwarf and the ever-popular Magma Rager, all characters taken from Blackrock Mountain, apparently confirming the speculation regarding the theme of the adventure.
  • Screenshots of several claimed cards from the new content are released through third-party forums.
"Blackrock Mountain, a Hearthstone adventure!"

March 3

  • The official PlayHearthstone Twitter account tweets an image of a Hogger plushie holding a Hearthstone plushie, with the caption "Adventure Awaits!" (see right).[16] The background also appears to depict Redridge Mountains, a zone immediately to the south of the Burning Steppes, the zone in which Blackrock Mountain is located.

The next bit of news won’t come by carrier pigeon — thankfully, we have much better ways of communication now. Victory awaits.[23]


July 8

  • The latest The Innkeeper's Tale blog is released, apparently a teaser for the coming expansion. The blog specifically describes a large gathering, with everyone wearing plate - even the magic users and murlocs - as well as a unicorn. The blog ends by teasing that all will be revealed soon.
Argent Tournament - sword.png

July 9

  • The official PlayHearthstone Twitter account begins a series of tweets with a theme of "champions".

July 15

"From east to west, heroes are sent, seeking glory in the greatest of events..."

August 24

October 20

  • Added with Patch 3.2.0.10604, Hearthstone launches in Japan, with a fully localised client. This is the first major new territory since China's addition during the game's beta. Players in Japan are granted immediate access to the current version of Hearthstone, including all card sets, making this the first territory to join the game in a relatively advanced stage.

November 4

"Oh the weather outside is frightful, but the Inn is so delightful. With our decks all good to go, Play Hearthstone! Play Hearthstone! Play Hearthstone!"

December 9

  • Hearthstone's first seasonal event is added, in the form of Winter Veil. The event brings snow-laden versions of the Stormwind and Orgrimmar battlefields, festive Greetings emotes, a sale on Classic card packs, and a themed Tavern Brawl - Gift Exchange - awarding the special "Winter Veil Wreath" card back.

December 15

  • As part of efforts to reduce downtime following the release of new Tavern Brawls, the release schedule is changed to have new Brawls debut in the Americas region instead of the Europe region, better suiting the development team's working hours.[25]

2016[edit | edit source]

Standard format Year of the Kraken promotional banner.jpg

February 2

  • Plans to introduce game formats are announced, providing a solution to the problem of the game's ever-increasing card pool. Scheduled for spring 2016, it is stated that the arrival of Standard format will also see balance changes to numerous Basic and Classic cards, as well an increase in the pace of the release cycle, with two new expansions and one new adventure each year.[26]

March 4

  • A blog on the official site announces that Hearthstone will become available in Thailand, as part of the Americas region, later in the month.[27] Senior Game Producer Yong Woo explains, "It's took a little while for the Innkeeper to learn Thai, but he's super excited to try it out!"[28]
  • A blog announces that the upcoming expansion will be revealed in a live stream on March 11. The blog begins with the text "Something inside the Tavern stirs . . . what could it be? Don’t worry – you won’t be alone!", inviting readers to "Tune in March 11 at 10:00 a.m. PST to see what has been lurking unfold live on Twitch!"[29]
The arrival of the expansion was heralded by the creation of murals such as this one in Brooklyn, New York

March 14

March 16

  • A few days after being revealed, a special poll is opened on the official forums allowing players to vote on which text will become C'Thun's official flavor text, as seen in-game in the Collection. The poll, titled The Old God C’Thun DEMANDS flavor text, mortal!, runs from March 16 to March 20, and is presented with the introduction "The bane of contact lenses everywhere, the ancient many-eyed Old God C’Thun is great at winking, but not particularly good at describing itself. That’s where you come in! Cast your vote on what flavor text makes it into Hearthstone for the Legendary card, C’Thun!" While voting on card reveals has become common practice for new releases, this is the first time players have been able to determine actual in-game content, albeit only flavor text.
"Now I've got a tale to tell you... of the ones from long ago."

April 24 - Patch 5.0.0.12574

  • 'Sorry' emote is replaced by the new 'Wow' emote
  • The largest set of card changes since the game's release is made, nerfing Basic and Classic cards in preparation for game formats
  • The special quests that originally awarded the Reward cards are removed, with the cards now craftable
  • The addition of card data for Fandral Staghelm marks the first time a set had added new cards to another set, with Whispers of the Old Gods serving to add three new minions to the Classic, Blackrock Mountain and The Grand Tournament sets
"Aaaaaaughibbrgubugbugrguburgle!"

April 26

  • Whispers of the Old Gods is released in the Americas region
  • Game formats are added to the game, and the first Standard year - the Year of the Kraken - begins

June 11

The image features leaflets for three destinations: Icecrown Citadel, the Vale of Eternal Blossoms and the Dark Portal, with the image of each destination featuring the Old Gods' distinctive tentacles invading the area.[37] Some speculated that this could be a teaser for an upcoming adventure, or another feature.
No Wonka Bar purchase necessary.

July 12 - Patch 5.2.0.13619

July 16

  • Players at a Fireside Gathering on the UCI campus in California receive a special golden invite. The invite reads,
"You are cordially invited to a most majestic, marvelous, magical event, the likes of which have never been seen before! It is our most sincere hope that you'll be able to join us!"
The invite is widely taken as referring to the upcoming revealing of the game's next adventure.

Teaser invite July 19 2016.jpg

July 19

  • Evidence begins to surface of an upcoming Public Test Realm.[38]
  • Emails are sent from the developers to the fansites and other game press containing a special invite,[39] reading,
"Greetings, my dear friend! Your valiant effort and masterful display of strategy in channeling the power of the Old Gods has won you the admiration of people across Azeroth.
We would would be honored if you would join us for a once-in-a-lifetime event that will be full of magic and celebration. We also have something very special in store for you!
Please be prompt, as we have an unforgettable adventure planned!
[Stream date and link]
Sincerely,
An old friend!"
Both the invite's text and graphic details are widely taken as confirming Karazhan as the upcoming adventure, with the visual style and celebratory tone making many think of a "magical dinner party" at the tower, and the feathers seen at the top and bottom of the invite widely assumed to represent Medivh.
"He’s got dance moves like a man possessed! …oh."

July 22

  • Paper versions of the email invites previously sent out are sent to members of the Chinese community, coming in decorated envelopes complete a ribbon and Hearthstone swirl wax seal. The text of the invites is largely the same, but also includes a footnote translated as "Please open at night". When opened in the dark, the invite was revealed to feature glow in the dark properties, with the embossed sections illuminated in similar colours to the email invite, but with one notable difference: the star in the top-left corner is replaced by a glowing eye, precisely matching the design shown on Arcane Intellect.[40]
  • The official Hearthstone Twitter account begins tweeting images of preexisting card art, modified to fit a "party" theme.

July 25

  • An official announcement confirms that the upcoming adventure will be revealed in a special presentation stream from China, making it the first Hearthstone content to be revealed from somewhere other than the US.[41]

Greetings from Gadgetzan teaser.jpg

October 20

October 24

  • The official Twitter account releases what appears to be a teaser for the upcoming expansion, titled "Greetings from Gadgetzan".[45] The image contains a lengthy hidden text in exceedingly small letters, providing comprehensive disclaimers for any and all eventualities that may result due to visiting the city or receiving the goblin-made postcard.

October 25

  • Apparently as part of the same teaser campaign, the official Twitter account posts the first of several pages of the "The Gadgetzan Gazette" ("The city's BEST newspaper. The city's ONLY newspaper.").
"Gadgetzan, where the gangs rule the streets..."

November 2

  • The official Instagram account posts an image of the Gadgetzan postcard, along with a handful of pirate coins bearing the text "Absolutum Dominium".[46]

November 4

Hearthstone logo.png

Mid-November

  • Blizzard quietly change the title of the game from Hearthstone: Heroes of Warcraft to simply Hearthstone. Logos on the official site are changed, and the developers ask the moderator's on the game's subreddit to update their logo to match the new title, but no press release or statement is made. The change is widely considered to mark (if somewhat belatedly) the game's shedding of its initial identity as a "spin-off" from the Warcraft games.[47][48] Yong Woo would later confirm the change was not intended to mean "anything special".[49]

November 25

December 1

  • Mean Streets of Gadgetzan is released in the Americas region, followed by the other regions on December 2.

The announcement also includes a teaser image showcasing hints for the content planned to be released during the year.
