The Boomsday Project Puzzle Lab.


"A LOT of SCIENCE happens at Boom Labs, and that means that there are dozens and dozens of unfinished or abandoned experiments hidden away in the complex. It’s a golden opportunity for a certain clever someone to figure out what the heck went wrong! Can you unravel their mysteries without exploding, dissolving, or becoming irrevocably poultry-ized forever?
When you experience The Boomsday Project’s free single-player content, The Puzzle Lab, you’ll discover that science is fun! And dangerous! Not necessarily in that order!"[1]

Puzzle Lab option in the Solo Adventures menu.

Selecting a Puzzle.

The Puzzle Lab is a free single-player game mode added with the The Boomsday Project expansion. The mode became available on August 21, 2018, two weeks after the release of the expansion.[1]

The Puzzle Lab is categorized into various puzzles that the player will have to solve:[2]

  • Lethal: Destroy the enemy hero in a single turn.
  • Mirror: Create a board state in which both sides are perfect mirrors of one another, including minion positioning, attributes, etc.
  • Board Clear: Clear the battlefield of all minions.
  • Survival: Survive the enemy's Hero Power (by healing to full, plus some Armor in higher difficulties).

  • This was the hardest puzzle by far that most Twitch streamers struggled with.[3]
  • One strategy is to calculate the number of unique-health minions that are required to be on the board if the health of the maximum-health minion is known. Then the number of duplicate-health minions that are allowed on the board can also be determined.
  • It can help to make a spreadsheet of the available healths each minion can have.
  • The difficulty of the puzzle is attributed to the vast number of possible permutations of card plays and card targets available, with some sequences leading very close to a solution where only one health number is missing from the board.
