In the Puzzle Lab you will face puzzles that will require you to find lethal in one turn, create a perfectly mirrored battlefield, clear the battlefield of minions, and survive against your opponent’s next onslaught. Here’s the official breakout of how all of these are explained by Blizzard:

  • Lethal (Destroy the enemy hero): In this experiment, the assistant is tasked with neutralizing the opponent in one turn using the cards at their disposal. We expect this will provide valuable insights into the destructive properties of many of our inventions.
  • Mirror (Create a perfectly mirrored battlefield): These tasks challenge the assistant to create a board state where both sides are perfect mirror images of each other: minion positioning, health, attack, etc. This should yield plentiful data on various means of board manipulation.
  • Board Clear (Clear the battlefield of minions): Pretty straightforward: clear the board of all minions. Our research suggests that minions play an important role in winning matches, and this set of challenges will help us better understand how to get rid of them.
  • Survival (Survive the enemy Hero Power): Finally, the Survival trial requires the test subject to restore their own health in order to survive their opponent’s next onslaught. A recent study has shown that dropping to zero health inversely correlates with winning games, and this experiment will further explore that relationship.

If you are able to complete all of these experiments you will go against Dr. Boom himself in a one-on-one showdown in his personal workshop! If you can take down Dr. Boom you will be rewarded with this awesome card back!

We’ll eventually have tips and tricks with guides to help you complete all of the experiment, so stay tuned! Remember that this will be released two weeks after the actual expansion release!

    My only worry with this game-mode is that there will only be a single solution to the puzzles so once it’s complete there won’t be any replay value. That’s something i really enjoyed about dungeon run and monster hunt was the replay. I hope there are multiple solutions to find <3

      I honestly worry more that solution will force you to craft a bunch of useless cards

    Good thing we get a cardback. New ones are really hard to come by. That’s how you get the playerbase to play a different mode than standard! GJ Blizz

    I was waiting for this kind single player mode in this game similar to the puzzle mode from yugioh video games that requires you to find the lethal.

    This looks awesome and super skill-based. Good job Blizzard for giving us something we haven’t seen before.

    Sounds interesting and not too RNG based like the other single player contents.

    Time will tell.
