A student project, a Chicago studio and a patent.

Operation started as a class assignment. HuffPost reported in October 2014 that John Spinello, then an industrial-design student at the University of Illinois, had been set the task of making an electric game in which a player guided a metal wand into holes without touching their metal edges. The dates given for his prototype vary by source: the toy historian Todd Coopee, writing on Toy Tales in 2018, dates it to 1962, while English Wikipedia gives 1964. Coopee describes it as an electrified box about 10 by 10 inches, wired to a 12-volt lantern battery and a 6-volt bell.

A family connection took the prototype to Marvin Glass and Associates, a toy design and engineering studio in Chicago, according to both Toy Tales and HuffPost. Spinello told HuffPost that when Glass touched the wand to the metal plate, the game buzzed and a spark jumped from the stylus. Spinello sold his rights in the game to the studio, the 2014 report says.

The studio patented the idea. United States patent 3,333,846, titled “Game Utilizing Electric Probe”, was filed on 4 February 1965 and granted on 1 August 1967, and is assigned to Marvin Glass and Associates; Google Patents shows it naming Marvin I. Glass, Gunars Licitis and John O. Spinello. That patent covers the mechanism — a hand-held probe that closes an electric circuit when it touches a conductive edge — rather than any theme.

The medical theme came later. Toy Tales says the concept became a Western-themed game called Death Valley, in which players steered a metal probe across an electrified desert board past hazards such as gunfire, rattlesnakes and mirages. The game was then licensed to the Milton Bradley Company of Springfield, Massachusetts, which, Coopee wrote, kept the play idea but changed everything else, turning the board into an operating table. English Wikipedia’s list of the studio’s work credits Operation to Marvin Glass and Associates and Milton Bradley in 1965.

Milton Bradley, Cavity Sam and Hasbro.

Operation went on sale in 1965; English Wikipedia gives a release date of 27 March that year. The patient is a cartoon man called Cavity Sam, lying on a lithographed operating table with a large red bulb for a nose, according to Wikipedia. Toy Tales describes the original release: twelve holes in Sam’s body, each holding a removable plastic part with a joke name such as Wrenched Ankle, Butterflies in Stomach or Spare Ribs, which Milton Bradley called “Funatomy” as a group. Players used wired metal tweezers; if they touched the metal sides of a hole, a buzzer sounded and Sam’s nose lit up red. The board ran on batteries hidden underneath.

The play turned the probe game into a card game as well. Toy Tales and Wikipedia both describe Doctor and Specialist cards that decide which operation is attempted, with play money paid for each piece removed and the richest player winning at the end. Coopee wrote that the original television advertising told viewers the game “takes a steady hand”, and HuffPost reported that Operation was heavily advertised on television by the early 1970s.

On 5 May 1984 The New York Times reported that Hasbro, the toy maker based in Pawtucket, Rhode Island, had agreed to acquire the Milton Bradley Company; Toy Tales says Hasbro took over the rights to Operation with it. English Wikipedia says Milton Bradley was folded into Hasbro Games in 1998 and that the Milton Bradley name was retired as a brand in 2009. Hasbro has owned Operation since 1984.

The cast of ailments has been revised. English Wikipedia, citing a 2003 report on About.com, says a fan vote titled “What’s Ailing Sam?” added an ice-cream cone in Sam’s head, called Brain Freeze, in 2004, ahead of Tennis Elbow and Growling Stomach. Licensed editions followed, among them a Shrek edition in 2004 and later Simpsons and Spider-Man versions, HuffPost reported. In 2014, the same report’s update said, Hasbro bought Spinello’s original prototype from his family. Hasbro’s current listing for the standard game, sold under Hasbro Games, describes ailment parts, a rubber band and a pair of tweezers, in what the company calls “Try Me” packaging.

Design and documentation.

A board game brand is carried less by any single object than by a set of printed parts that travel together: a box lid, a board, a handful of tokens or dice, and a folded sheet of rules. The lid does most of the public work, because it sits on a shelf and has to name the game, show what kind of play is inside and carry the maker’s mark, often at a size that reads from across a shop.

Inside, the board turns the game’s logic into a layout of spaces, tracks and colour-coded zones, and the tokens, cards and score pads repeat that colour code in miniature. Rule sheets are the quiet part of the identity, with their own headings, diagrams and house style, and they are often revised when a game is reissued.

Game names also change hands more often than their players notice, so the company printed on a lid may not be the one that first published it. Each guide separates what dated, independent sources record about a game’s origins, owners and editions from what the companies say about themselves.

A circuit dressed as a patient.

The Operation identity is a piece of engineering in costume. The patent of 1967 describes nothing more than a probe, a circuit and a conductive edge; the Death Valley version, as Toy Tales tells it, dressed the same circuit as a desert. Milton Bradley’s version made the circuit into a body, so that the buzz of a mistake and the red light of Sam’s nose became the character’s reaction rather than a machine’s signal.

Cavity Sam carries much of the visual brand. His outline, his bulb nose and the shapes cut into the table are what a player looks at for the whole game, and the pieces are drawn as visual puns on figures of speech — a wrench in the ankle, butterflies in the stomach, a pail of water on the knee, according to English Wikipedia. The jokes sit in the names and the objects rather than in long text on the board.

The mark itself has been redrawn over the years. English Wikipedia illustrates a logo that it dates to 2013, and the game has been issued in licensed editions in which another character takes Sam’s place on the table while the probe, the tweezers and the buzz stay the same. That pattern keeps the original circuit at the centre of each version.

For a design guide, Operation shows how a plain electrical idea becomes a brand once it is given one memorable character, one sound and one light. Compare it with Chutes and Ladders, the Milton Bradley board game of 1943, and Candy Land, another Milton Bradley game now owned by Hasbro. For this guide we use theatre teal, nose red and patient peach with a sans, an unofficial interpretation; no product or logo is reproduced.
