How the gambling industry has kept up with decades of computer-assisted tech developed to beat roulette, like wearable devices, timers, and predictive software
One spring evening, two men and a woman walked into the Ritz Club casino, an upmarket establishment in London's West End. LinkedIn: John Connolly , Christine C.

Cook : It is practically impossible to predict the number that will come up," Stephen Hawking once wrote about roulette. “ Otherwise physicists would make a fortune at casinos. … David Sharratt : Fascinating big read on how the seemingly random nature of a roulette wheel has traits of predictability. … Peter Cohen : If you've got an interest in the gambling business, you might find this read to be quite fascinating. — https://www.bloomberg.com/... Tweets: Barry Ritholtz / @ritholtz : The most fascinating column you will read today: “For decades, casinos scoffed as mathematicians and physicists devised elaborate systems to take down the house. Then an unassuming Croatian's winning strategy forever changed the game.” https://www.bloomberg.com/... Jared / @jaredhstocks : 1/ Roulette, “an unbeatable game unless someone steals money from the table when the croupier isn't looking.” -Albert Einstein. That is until Niko Tosa, a gambler who did the impossible. How we can use the story of Tosa to beat the Stock Market? https://www.bloomberg.com/... @rxgamble : I've never heard the term “cerebral clocking.” I've had a lot of discussions over whether or not roulette is beatable without a device and I always say yes and everyone else says no, but I'm an optimist. https://www.bloomberg.com/... Venkat Ananth / @venkatananth : this is a great @bw read on niko tosa, a croatian gambler, whose methods (where he places the bets a few seconds into the spin) have beaten the roulette every time, while also changing the game forever. https://www.bloomberg.com/... Matt Glassman / @mattglassman312 : I enjoyed The Eudaemonic Pie when I read it in the 90s, but I really couldn't decide if it was a true story or just straight fiction pretending to be non-fiction. This fascinating piece confirms it was real. Physics isn't random. Great read. https://www.bloomberg.com/... Tren Griffin / @trengriffin : “They would wait until six or seven seconds after the croupier launched the ball, when the rattling tempo of plastic on wood started to slow, then jump forward to place their chips before bets were halted, covering as many as 15 numbers at once.” https://www.bloomberg.com/... Jeff Erickson / @jeff_erickson : This was so good: “A mysterious gambler shocked casinos around the world by doing the impossible: beating roulette” https://www.bloomberg.com/... via @BW Chris Skinner / @chris_skinner : This is fascinating. No computer involved? Just bad roulette tables. “He ... had heard rumors of another who'd tried to get a microprocessor surgically embedded in his scalp. Yet Tosa had never been caught with so much as a thumb drive.” https://twitter.com/... @business : Roulette was supposed to be a game of chance, until one gambler cracked the code. For the first time, we find out how he did it (via @quicktake) https://www.bloomberg.com/... https://twitter.com/... Dr. Hugh Akston / @akston_capital : Fun article by @KitChellel about an obscure gambler that figured out something the rest of the world was ignoring. Reminds me of Ed Thorpe with options or Jim Simons with quant. Good reminder that “edge” is all around us if we look hard enough. https://www.bloomberg.com/... James Cham / @jamescham : Hard to beat an article that includes Claude Shannon, the first wearable computer, utopian communities, Game of Thrones, and beating roulette. https://www.bloomberg.com/...
Context & Ripple Effects
The Bloomberg piece traces an arms race back to its origin point: Claude Shannon's early wearable computer, built to exploit roulette's physics, and forward through timers and predictive software to the Ritz Club incident, where a gambler's timing-based betting repeatedly beat the wheel and forced the casino to change its practices. The throughline is that every edge a player has built with compute, the house has eventually absorbed into its own defenses.
That dynamic is no longer confined to the wheel. In skill games, pros now augment play with AI-generated optimal poker strategies, and an amateur Go player recently beat a top-ranked AI system using tactics surfaced by a program that had probed that AI for weaknesses — evidence that human-plus-computer play is outpacing both lone machines and unassisted humans.
First-order effects
- Casinos like the Ritz Club must treat every customer as a potential sensor-carrying analyst, hardening tables and surveillance against wearables, timers, and latency-exploiting bets after Niko Tosa's repeated wins proved the threat was real, not theoretical.
Second-order effects
- The house side is professionalizing: sports-data firms like Sportradar now build the same kind of predictive models the advantage players once carried covertly, setting odds designed to keep bettors betting — the countermeasure has become a product line.
Third-order effects
- If the pattern holds, the contest stops being gadgets versus dealers and becomes model-versus-model: individuals lose access to exploitable edges as institutions operationalize detection and pricing, while hybrid human-AI play keeps forcing rule changes in both chance and skill games.
The trend: Across games of chance and skill, compute is migrating from lone advantage-players' hidden devices to institutionalized model-building by the house, making the arms race itself the industry's core technology.
