Abstract
Examples herein include systems for detecting cheating in card games, including bridge. The system can acquire board data for multiple events, the events including bridge games. For each event, determining performance values for a player based on the board data, wherein the performance values may additionally be based in part on timing data. The system can detect a deviation of by comparing the performance values against a threshold, wherein the threshold is based on past performance of known cheating players. Then the system can alert a user when the likelihood of cheating exceeds a threshold.

A system for detecting cheating players in a card game, including:
- a non-transitory, computer-readable medium containing instructions;
- and
- a processor that executes the instructions to perform stages comprising:
- acquiring board data for multiple events, the events including bridge games;
- for multiple boards in each event, determining performance values for a player based on hand records, player names, a table result, contract, and declarer;
- detecting a deviation of by comparing the performance values against a threshold, wherein the threshold is based on at least one of past performance of known cheating players and optimal bridge behavior;
- and
- alerting a user regarding a likelihood of cheating when the deviation is detected.
