We sit down with Blizzard to discuss Puzzle Labs, the exciting new single-player component for the game's latest science-themed expansion The Boomsday Project. A simple idea that adds a new layer to the Hearthstone story, and a new way to play and think about strategy in a card game.

“When we were preparing for The Boomsday Project, we knew this was the perfect opportunity to do puzzles,” Dave explains. “It's an expansion about science and experimenting with things, and a lot of the puzzle mechanics really do feel like science problems. Like trying to create the perfect chain reaction or solve this mystery.” And so, from there the initial idea and testing that had been carried out for a number of years at varying levels was now brought to the fore.

But before Puzzle Labs would become a fully playable part of Hearthstone, the team at Blizzard had to solve a few puzzles of its own. Being able to reset the board quickly, make it so puzzles could be tackled one after another without going through load screen after load screen, and being able to pick things up where you left off. It was a challenge that came together quickly – but then opened the door to an exciting new way to play Hearthstone.
