- "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).
