The “Hold” and “Sleight Release” (Dealer Controlled Outcomes)
How it works
A skilled but dishonest dealer can subtly influence outcomes through two primary techniques: The Hold: the dealer waits to release the ball until the wheel has slowed to a specific speed, allowing them to better predict (or control) where the ball will land. By waiting for a specific number to pass under their hand before releasing, the dealer can bias outcomes toward a target sector. The Sleight Release: the dealer uses a subtle hand motion or finger pressure at the moment of release to influence the ball’s trajectory, speed, or spin axis. While no dealer can guarantee a specific number will hit, a skilled practitioner can bias results toward a sector with enough consistency to give a confederate a mathematical edge. These techniques require extensive practice and are nearly invisible to casual observation.

On the record
The question of whether dealers can deliberately influence outcomes has been debated for centuries. Most experts agree that while perfect control of a single number is impossible, subtle sector bias through controlled release is theoretically achievable by a highly skilled practitioner: which is precisely why casinos have implemented so many countermeasures.
