Collusion
Definition
Coordinated play between accounts to defraud an operator or other players, particularly in poker. A core integrity issue.
Why it matters
Collusion is the most distinctive integrity threat in poker. Two or more players coordinating their actions at a table can extract value from honest players in ways that are statistically detectable but operationally difficult to prove case-by-case. The classic patterns include soft-play between known associates, chip dumping (intentionally losing to transfer balance), and coordinated betting to trap third players. Poker operators run dedicated game-integrity teams that analyze hand histories at scale using statistical models trained to flag suspicious patterns.
Collusion extends beyond poker. Bonus abuse rings coordinate registrations across multiple accounts to claim repeat welcome bonuses; sportsbook collusion can involve coordinated placement of arbitrage or value-positive bets across operators. The detection toolkit overlaps with broader fraud detection: device fingerprinting, network analysis, behavioral biometrics, payment graph analysis. Networks share signals via industry information-sharing arrangements where regulator-permitted.

Frequently asked questions
How is collusion detected in poker?
Statistical analysis of hand histories at scale. Specific patterns include unusually high mutual chip transfer between accounts, abnormal fold patterns when specific other accounts are at the table, and IP/device clustering. Game-integrity teams investigate flagged sets manually before action.
What happens to colluding players?
Account closures, balance forfeiture per T&Cs, and in egregious cases, referral to regulators or law enforcement. Cross-operator information sharing means colluding rings often get blocked across multiple poker networks once detected at one.
