Moritz Waldemeyer decided to take up the challenge of redesigning the game “Operation.” He came up with a 3D version called Keyhole Surgery in which you have to place the key in a maze without touching the sides. He included a file so that you can study it before you give it a go. The person with the least amount of touches wins. We dig the idea of the prototype game, but this is definitely not one to play at a kegger.
