Gustav Kirchhoff is annoyed because nobody appreciates his circuit laws\! You get transported to his secret lair and won't be able to get out until you show mastery\!    The first\-person game "Kirchhoff's Revenge" teaches the basic concepts of electrical circuits; players need to solve puzzles by assembling macroscopic circuit elements such as batteries, light bulbs, wires, volt meters, and ampere meters\. These circuit elements snap together into functional, three\-dimensional structures\. Moving "charges" are indicated, so as opposed to real circuit elements, currents are visible\. Puzzles increase in difficulty and complexity, while side rooms and pre\-assembled circuits offer opportunities to learn new concepts\.     Game play is strictly based on solving puzzles, there are no dexterity or timed challenges\. Once players succeed, they actually get a Schwarzwälderkirschtorte, which they may dispose off as they see fit\. The cake is not a lie\.    The game has been used in physics courses at the high school and introductory college level, and it is now made available as Early Access to the wider community\.
