  "country": "US",
  "title": "How the Classic Operation Board Game Works",
  "original_title": "Game utilizing electric probe",
  "summary": "A 1967 patent for an electronic game where a player uses a conductive probe to navigate a path without touching the sides, triggering a signal if they fail.",
  "what_it_does": "The patent describes a game board featuring two parallel, electrically conductive plates separated by a gap. A path for the player is created by a series of openings in the top plate. The player uses a specialized probe—an elongated member with a spring-loaded conductive rod—to navigate these openings. If the rod touches both the top and bottom plates simultaneously, it completes an electrical circuit, which triggers an indicating signal device, such as a light or buzzer.",
  "what_it_does_not_cover": [
    "Does not cover non-electrical games that rely purely on mechanical dexterity.",
    "Does not cover games that use wireless sensors or cameras to track movement.",
    "Does not cover games where the signal is triggered by something other than a direct electrical short between two plates.",
    "Does not cover games that do not use a spring-loaded probe mechanism."
