The mystery has been solved!

Note: If you cannot join a game against the Innkeeper it is because the servers are full. Try again later!

On May 4th, Blizzard patched Hearthstone with Patch 20.2 that brought Quilboars into Battlegrounds, a shiny new Diamond Ragnaros, new Tier 2 Hero Skins, and so much more. The best addition though was by far the activation of a new achievement, "???" that rewards us with a new card back which was one of the runner-ups in a competition that was run over in China earlier this year.

The community is out in full force seeking answers. What could be the 4 different mysteries that we have to solve in order to obtain the card back?


What We Know So Far

Although Celestalon has stated that there will not be any hints, he has had a few words of wisdom for us all.

  • We do not need World of Warcraft.
  • It does not appear we need to have a full collection of Barrens cards to solve the mysteries.
  • One specific part of the mysteries will be harder to do on mobile but remains possible.
    • This is not the first part of the mystery.
    • We can infer that this requires all the mysteries to be completed in a certain order.
  • Mobile users should also be able to participate in the achievement without issue tells us anything desktop-specific to Hearthstone could be ignored.

Does it involve having a full collection of Barrens cards cuz I don’t know if I should even bother with it?

You can do it. (Source)

And from the WoW Secret Finding Discord:

Quote From Celestalon

You can all solve it.


I'll be up-front about one thing: There is one specific part of this whole mystery that is harder to do on Mobile (but still possible). However, you're nowhere even remotely close to it right now. It's safe to assume that mobile players can help just as much as desktop players right now. And no, nothing in this message is a clue.


Possible Hints

None of these are confirmed to be useful, but Celestalon has been sneaky so who knows!

The night before the new patch hit, Celestalon teased everyone with a glowing, blue question mark.

How to Solve Barrens Mystery #1

Initially solved by LynxZh on the WoW Secrets Discord.

We're going to be fighting The Innkeeper as Rogue with the following Rogue cards in our deck:

We're also going to include Efficient Octo-bot so we can reduce the cost of these cards. We'll need to play them all in a single turn.

To start your match against the Innkeeper, go to "Solo Adventures" followed by the "Practice" category where you can queue for a Normal game. You may play against any of the Innkeeper's heroes.


Now, you need to draw all five of these cards and play them in the same turn to progress to the next phase. As stated above, we'll use Efficient Octo-bot to make this happen. Once they have all been played, in any order, and you end your turn, a new spell will be added to your hand.

  1. Get all 5 cards in your hand.
  2. Reduce their costs so you can play them all in one turn.
  3. End your turn.
  4. A ??? Spell will be added to your hand.
  5. Play the ??? Spell.

 Playing this card is going to reset the board to a new state with a full field on your opponent's side, that contains some magical cubes, and three rings of keys on yours. Your hero power will also be changed.

What you do in the next part is VERY important. This is a puzzle that is solved by setting the enemy minions to a certain attack. This is effectively a 7 digit lock.

You will only be attacking with your left-side minion to set this lock.


Only attack with your first, or left-most minion.

Perform the following actions to complete the mystery in order, from left to right on the opponent's board. Remember, only attack with your left-side minion.

  1. Attack your opponent's first minion once. (Far Left)
  2. Attack your opponent's second minion twice.
  3. Attack your opponent's third minion three times.
  4. Do not attack your opponent's fourth minion. (Middle)
  5. Do not attack your opponent's fifth minion.
  6. Attack your opponent's sixth minion three times.
  7. Attack your opponent's seventh minion twice. (Far Right)

These attacks will change the attack and health of the enemy minions. It is all over when the following board state is achieved, with all enemy minions having 4 attack:

After these attacks are carried out, press your hero power. The game will end and you will now have achieved 1/4 progress in the mystery.


How to Solve Barrens Mystery #2

Initially solved by MustBeSenpai the WoW Secrets Discord.

We're going to be fighting the Innkeeper as Warrior with the following cards in our deck:

Much like the Rogue puzzle, hold all these cards in your hand and get ready to play them all in a single turn. Once they have all been played, in any order, and you end your turn, a new spell will be added to your hand.

  1. Get all 5 cards in your hand.
  2. End your turn.
  3. A ??? Spell will be added to your hand.
  4. Play the ??? Spell.

This is a challenging next part of the puzzle so pay close attention. Your new board that has been generated is filled with Orcs, Quilboar, and a Caravan.

  • Any minions to the right of the Caravan will be sent over to the other side when you hit your hero power.
  • You can drag and drop the minions on the board in any order, though they remain on the side they are on.
  • We will be sending minions from one side to the other in a specific order.

There are some bad scenarios that mean you've messed up:

  • If you send over only the Caravan, a centaur will spawn and kill it. 
  • If you send over the Caravan and three minions, Centaurs will spawn and kill them.

Here are the steps we need to take to solve this challenge. We've got the side of the board you want to be on for each of the moves.

  1. Yours - Move two Quilboar to the right side of the Caravan. [Hero Power]
  2. Enemy -  Move one Quilboar to the right side of the Caravan. [Hero Power]
  3. Yours - Move two Quilboar to the right side of the Caravan. [Hero Power]
  4. Enemy -  Move one Quilboar to the right side of the Caravan. [Hero Power]
  5. Yours - Move two Orcs to the right side of the Caravan. [Hero Power]
  6. Enemy - Move one Quilboar and one Orc to the right side of the Caravan. [Hero Power]
  7. Yours - Move two Orcs to the right side of the Caravan. [Hero Power]
  8. Enemy - Move one Quilboar to the right side of the Caravan. [Hero Power]
  9. Yours - Move two Quilboar to the right side of the Caravan. [Hero Power]
  10. Enemy - Move one Quilboar to the right side of the Caravan. [Hero Power]
  11. Yours - Move two Quilboar to the right side of the Caravan. [Hero Power]

Following these steps results in a victory and you will now have 2/4 completion.


How to Solve Barrens Mystery #3

Initially solved by the Korean Secrets Finding Team.

We're going to be fighting the Innkeeper as Druid with the following cards in our deck:

Much like the previous puzzles, hold all these cards in your hand and get ready to play them all in a single turn. Once they have all been played, in any order, and you end your turn, a new spell will be added to your hand.

  1. Get all 6 cards in your hand.
  2. End your turn.
  3. A ??? Spell will be added to your hand.
  4. Play the ??? Spell.

Now we're going to be going through a maze! Depending on which minion you attack decides how you move in the maze.

  • Attacking the left minion turns you left.
  • Attacking the right minion turns you right.
  • Attacking the middle minion will advance you forward.
  • When the immune shield is on the middle minion, that means there is a wall in front of you.

You will notice that there are a limited number of left turns due to the low health of the left-side minion. Luckily, we can turn ourselves right three times to effectively make a left turn.

The solution is to make it through the following path. Each letter is an attack that corresponds to the minion.

(L=Left, M=Middle, R=Right)

RRRMM RMMRM RRRMR
RRMMR MMRRR MMRMR
RRMMM MRRRM MMRMM
RMMRM RRRMM MMMRM
MMRMR RRMMR RRMMR
MMRMR RRMRM RRRMR
RRMRM MMMRR RMMMR
