There have been instances where individuals have successfully employed various methods to cheat at roulette. Below are four methods that have proven to be effective:

1. Sleight of Hand:

• Accomplished cheaters often assume the roles of players in roulette games with high activity levels, honing their sleight of hand and misdirection techniques over years.
• Some cheaters can place bets after the ball has landed on the wheel, utilizing techniques like past posting. This involves deceptive actions to place bets on the winning number after the ball has settled.
• Notable cheaters, like Richard Marcus, have mastered strategies such as The Savannah, The Roulette Mix-Up, and The Roulette Section. These tactics involve skillful misdirection and collaboration with croupiers.

2. Roulette Computers:

• Roulette computers pose a serious threat to the game, with conflicting opinions about their effectiveness. Some argue they are ineffective in actual casino settings, while others claim they are the only way to make accurate predictions.
• These devices consist of components such as a navigator, tracker, computation device, and a headset. The navigator records wheel data, the tracker records the relative positions of the ball and wheel track, and the computation device predicts the landing location of the ball.
• Some individuals go to great lengths to use roulette computers, seeking casinos in distant locations where their use is not strictly forbidden.

3. Biased Wheels & Advantage Play (AP):

• Advantage play involves exploiting inefficiencies in the game, such as biases in roulette wheels favoring certain numbers.
• García Pelayo, a renowned Spanish player, successfully identified biases in roulette wheels at Casino Gran Madrid during the 1990s. He collected data from thousands of spins, used a computer program to analyze it, and then took advantage of the identified biases in different casinos globally.

4. Rigged Wheels, Balls & Magnets:

• In rare cases, cheaters have rigged roulette wheels or used tiny, undetectable magnets on the ball to control its movement from a distance.
• Pierre Dugal manipulated a roulette wheel in the 1800s, ensuring certain numbers appeared more frequently. His method involved hiding in the restroom after the casino closed.
• Monique Laurent gained notoriety in 1973 for rigging the roulette ball using a radio receiver and a transmitter concealed in a cigarette pack, assisting the team in winning over $1 million before being exposed.

It is essential to note that resorting to cheating in any form is against the rules of fair play and can result in severe consequences, including legal action and banning from casinos. This information is presented for educational purposes only.
