The Goblins vs. Gnomes board in Hearthstone features a spiff-tastic rocket in the upper-left quadrant.
Once, while playing with the beam-zapper in the bottom-right quadrant, I positioned it just right, and the beam hit the satellite, powered the rocket, and sent it blasting off the board.
The problem? I haven't been able to reproduce it since!
What's the secret there? How do I align the beam-zapper and send the rocket into the stratosphere?
