Scam #16: Laser Scanner Prediction System

How it works

A sophisticated evolution of the roulette computer that uses a concealed laser scanner to measure the velocity and deceleration of the ball and wheel. The laser, typically hidden inside a mobile phone or small handheld device, projects an invisible beam that precisely tracks the ball’s position and speed as it travels around the track. The data is fed to an onboard microprocessor that calculates the ball’s likely landing zone using complex physics algorithms. Some systems also track wheel speed simultaneously. The prediction is relayed to the bettor via an earpiece or vibration signal. Early press reports of the 2004 Ritz Casino case incorrectly described a laser scanner; the actual device used timing clicks, not lasers. However, laser-based systems are technically feasible and have been developed. The laser method offers higher precision than manual timing but is also more detectable due to the electronic components involved.

On the record

The 2004 Ritz Casino case generated widespread media reports about “laser scanners,” but insiders confirmed the actual device used manual timing input via mobile phone buttons, not lasers. The confusion highlighted how little was understood about electronic cheating devices at the time. Norman Packard, developer of the Eudaemons’ system, noted that a timing-based system would have been simpler and more practical than a laser-based one.
