Blizzard has released a new solo adventure for their highly addictive card game Hearthstone.
The new adventure is part of the Boomsday Project and it’s called “Puzzle Lab”.
The Puzzle Lab challenges players with 4 different “labs”. Each lab represents one of four puzzle types: Lethal, Mirror, Board Clear, and Survival. Each of them starts out simple and becomes more challenging as you get further.
For a limited time, everyone who logs in gets 3 free boomsday project card packs for free.
