Part II: Table Game Cheating · Roulette Cheating Methods · #3.9
Compressed Air / Pneumatic Ball Disruption
How it works
This method involves installing hidden nozzles or vents around the roulette wheel that can blast precise bursts of compressed air at the ball as it travels along the track or approaches the pockets. The air jets can either deflect the ball away from heavily-bet numbers or push it toward target numbers where confederates have placed bets. The system is controlled remotely via a handheld device or hidden foot pedal. Unlike magnetic methods, this technique leaves no magnetic signature and is harder to detect with standard anti-cheating tools. The air bursts must be carefully calibrated: too weak and they have no effect; too strong and the ball’s movement looks obviously unnatural.
Where it appears
Physical roulette wheels; requires pre-installation of equipment
On the record
While theoretically possible, compressed-air manipulation is not well documented in gambling literature. We found no documented case of compressed-air manipulation in a regulated casino; documented roulette gaffs have used electromagnets, mechanical pins or altered pockets instead. The technique is more commonly associated with rigged carnival wheels and illegal operations.
