John Spinello was still an industrial-design student at the University of Illinois when he built a plywood box wired to ring a bell, a class project he called “Death Valley.” He sold the rights for $500 and a promised job that never came. That prototype became Operation, a game that has since generated an estimated $40 million in revenue for the companies that owned it, according to Core77’s account of the sale. Spinello never got a cut of any of it. Five decades later, when he needed $25,000 worth of oral surgery he couldn’t pay for, it was strangers who’d grown up playing his game who covered the bill.

A Class Project, Sold Away

Spinello’s original device used a metal plate drilled with holes and crooked channels, with a metal probe that triggered a bell if a player’s hand slipped, according to Core77’s reporting. A family friend named Sam Cottone, who worked for toy designer Marvin Glass, arranged a meeting, and Glass bought the concept outright for $500 — about $5,100 in today’s money — along with a vague promise of future employment that never materialized, per the same account. Signing over the design meant signing away every future royalty. Marvin Glass and Associates, the design firm behind other mid-century staples like Mouse Trap, Lite-Brite, Rock ‘Em Sock ‘Em Robots and Simon, reworked Spinello’s prototype before selling it on to Milton Bradley, according to Core77’s account of the redesign. The metal probe became a set of tweezers, the ringing bell became a buzzer paired with a light bulb, and the plain holes were filled with themed plastic ailments like a pencil for “Writer’s Cramp,” per the same reporting. Milton Bradley released the finished game as Operation in 1965, according to Wikipedia’s history of the game. Milton Bradley was later absorbed into Hasbro, which still manufactures Operation today.

Decades With No Royalty Check

Spinello went on to other work, including running a warehouse business that failed in 2008, according to NPR’s reporting. By 2014 he was in his seventies and needed roughly $25,000 in oral surgery he had no way to afford, a fact confirmed by both NPR and CNBC. The irony of the game’s inventor being unable to afford a medical procedure of his own became the story’s hook, but Spinello himself didn’t dwell on the unfairness of it. Asked about it at the time, he kept his focus elsewhere, telling reporters he preferred to focus on “the joy that the game has brought to so many over the years,” a line documented by NPR.

Toy Designers Step In

Fellow game designers Tim Walsh and Peggy Brown launched a crowdfunding campaign on Crowdrise to cover Spinello’s medical costs. It drew more than 1,200 donors and raised $32,422, far beyond the original ask, according to the Chicago Toy and Game Fair’s account of the campaign. The story spread well past the toy world, picked up by outlets including Good Morning America, NBC Nightly News and Jimmy Kimmel Live, per the same report. Hasbro got involved directly too: the company let the campaign use official Operation trademarks and imagery, and separately bought Spinello’s original prototype, which it now displays at its offices in Rhode Island, according to Chicago Toy and Game Fair’s reporting. Walsh and Brown were far from strangers to the game’s history — both were toy designers who had spent years documenting how Operation influenced people’s career choices, and the crowdfunding campaign later pushed them to develop a documentary examining the game’s unlikely pull on the medical profession, per the same account.

A Company Finally Pays Up, Sort Of

The $500 sale from the 1960s never turned into royalties, and nothing about the crowdfunding campaign changed that legal reality — Hasbro’s purchase of the prototype and its support for the fundraiser were goodwill gestures, not a settlement. What the campaign did prove is that the debt owed to Spinello was never really about the corporate ledger. It sat instead with everyone who spent a childhood afternoon sweating over a set of tweezers, terrified of the buzzer, who found out decades later that the man who dreamed it up needed exactly the kind of help his game had spent sixty years pretending to give.
