Niko Tosa

Niko Tosa grew up in Serbia with a background in technology and engineering. He became fascinated with the physics of roulette and the possibility of using modern technology to predict outcomes. By the early 2000s, miniaturized computers and laser technology had advanced far beyond what Thorp and Shannon worked with decades earlier, opening new possibilities.

In March 2004, Tosa and two accomplices walked into the Ritz Casino in London and proceeded to win approximately £1.3 million (about $2 million) over two nights of play. They used mobile phones equipped with laser scanning technology to measure wheel and ball speeds, predicting landing zones with sufficient accuracy to overcome the house edge dramatically.

Tosa's system used a laser scanner to measure the velocity of both the ball and the wheel as they rotated. This data was transmitted to a computer that calculated the most likely landing sector. Predictions were communicated to the player via earpiece before betting closed. The team bet heavily on the indicated sector and its neighbors.

The Tosa case demonstrated that roulette prediction technology had become highly effective with modern miniaturization. It also established important legal precedent—British authorities concluded that using one's intellect and technology to predict roulette outcomes was not cheating under UK law. The team was allowed to keep their winnings.

Niko Tosa's Ritz Casino win proved that physics-based roulette prediction remained viable in the modern era. The case made international headlines and prompted casinos worldwide to implement new countermeasures including early ball-call cutoffs and wheel design changes. His legal victory established that technological advantage play could be legitimate.
