Algorithms designed to detect dealer patterns analyze historical gameplay data to find trends and anomalies in dealer behavior. They employ statistical analysis, machine learning, and artificial intelligence to investigate decision-making patterns and betting behavior over time. By processing extensive datasets, these algorithms can reveal subtle trends that suggest bias or consistent behaviors. This methodology is applied in both land-based and online gaming to promote fairness, enhance player experiences, and ensure game integrity, ultimately aiming to identify deviations from expected randomness in dealer actions.
