How Online Poker Sites Detect Collusion (Not Just RTA and Bots)
Updated: Sep 3
Online poker has never been safer than it is today, yet cheating remains one of the biggest concerns for both recreational and professional players. Whenever a player loses an unusual pot, accusations of “rigged games”, bots or collusion quickly appear on forums and social media.
In reality, modern poker rooms invest heavily in Game Integrity teams whose sole purpose is to protect the ecosystem. Their job isn’t simply to ban bots—they investigate collusion, multi-accounting, chip dumping, ghosting, prohibited software and every other form of unfair play. Leading operators state that their systems monitor games continuously using automated detection, machine learning and specialist investigators, with the vast majority of cases identified proactively rather than through player reports.
So how do poker sites actually detect collusion?
The answer is much more sophisticated than most players imagine.

❓FAQ
🤝 What Is Collusion?
Collusion occurs when two or more players secretly cooperate to gain an unfair advantage over the rest of the table.
Unlike ordinary strategy discussions away from the table, collusion directly affects live decisions during games.
Common examples include:
Soft playing a partner
Avoiding aggressive action against each other
Sharing hole cards
Chip dumping
Coordinated squeezing
Isolating recreational players together
Passing strategic information during play
Unlike variance, collusion creates a mathematical edge that honest players simply cannot overcome.
❌ Collusion Is Not the Same as Bots or RTA
Many players use these terms interchangeably, but they describe different types of cheating.
Type | Description |
Collusion | Multiple human players cooperate together. |
Botting | Software plays automatically. |
RTA (Real-Time Assistance) | A human receives solver recommendations while playing. |
Ghosting | Another player takes over or assists during a session. |
Multi-accounting | One person plays multiple accounts. |
Some investigations involve several of these behaviours simultaneously, but they are treated as separate violations.
🔍 How Poker Sites Actually Detect Collusion
One of the biggest misconceptions is that poker sites catch colluders after seeing a single suspicious hand.
That almost never happens.
Instead, Game Integrity teams analyse enormous datasets looking for behavioural patterns that repeat over hundreds—or sometimes thousands—of hands.
Modern detection is based on probability.
One unusual fold means nothing.
One hundred unusual folds between the same two accounts may mean everything.
📊 The Main Signals Poker Sites Look For
No single indicator proves collusion.
Instead, investigators combine many independent signals into one overall risk profile.
Signal | Why It Matters |
Same IP Address | Possible shared location |
Device Fingerprinting | Detects multiple accounts on the same hardware |
Playing Together Frequently | Unusual table overlap |
Soft Play | Players consistently avoid attacking each other |
Chip Dumping | Direct transfer of value |
Abnormal Fold Frequencies | Statistical deviations |
Betting Correlation | Coordinated decisions |
Session Timing | Accounts logging in and out together |
Network Relationships | Hidden links between player groups |
The key point is simple:
One signal proves nothing. Ten independent signals together become very compelling evidence.
🃏 Soft Play Is Often More Suspicious Than Huge Pots
Many players imagine collusion as enormous all-ins.
Ironically, experienced investigators often focus on something much more subtle.
Soft play.
Examples include:
never 3-betting each other;
checking back value hands;
making unusually tight folds only against one specific opponent;
avoiding thin value bets;
refusing to bluff.
Each individual decision looks perfectly reasonable.
The pattern only becomes visible after analysing large samples.
💸 Chip Dumping Is Usually Easier to Detect
Chip dumping is one of the simplest forms of collusion to identify.
Typical examples include:
intentionally losing massive pots;
making impossible hero calls;
calling all-ins with virtually no equity;
transferring chips between accounts.
These behaviours stand out quickly because they are statistically rare and financially meaningful.
📈 Poker Sites Think in Statistics, Not Individual Hands
Players often email support saying:
“Look at this hand! This proves collusion.”
Unfortunately, one hand almost never proves anything.
Professional investigators ask very different questions.
For example:
How often do these players sit together?
Do they avoid playing large pots against each other?
Do they consistently attack the same opponents?
Are their betting frequencies unusual only when facing each other?
Does the behaviour continue across different limits and formats?
The investigation focuses on long-term behaviour, not isolated outcomes.
🤖 Machine Learning Has Changed Everything
Modern poker security is no longer based solely on manual reviews.
Large operators publicly state that they use artificial intelligence, machine learning and proprietary analytics trained on billions of historical hands to identify suspicious behavioural patterns that humans would struggle to detect. Automated systems operate around the clock, generating alerts that are then reviewed by specialist investigators.
These systems can identify:
hidden account relationships;
unusual betting correlations;
abnormal decision frequencies;
behavioural clusters;
evolving cheating methods.
Rather than replacing investigators, machine learning helps them prioritise the most suspicious cases.
👨💻 Humans Still Make the Final Decision
Despite advances in AI, the final decision is rarely left to software alone.
Major operators describe review processes where automated alerts are examined by dedicated Game Integrity specialists, often followed by peer review before sanctions are applied. Teams include former professional players, data scientists and statistical analysts who evaluate both the numbers and the poker context.
That human element is critical.
Poker is too complex for a simple algorithm to understand every situation.
🚨 Can Innocent Players Be Flagged?
Yes.
Certain situations naturally attract additional scrutiny:
brothers playing together;
roommates sharing Wi-Fi;
staking groups;
travelling professionals;
players using the same computer.
However, sharing an IP address alone does not prove collusion.
What matters is whether the actual gameplay suggests coordinated behaviour.
This is why reputable poker sites combine technical information with statistical analysis before taking action.
🛡️ What Should You Do If You Suspect Collusion?
If something genuinely feels wrong:
Save the hand histories.
Record player names.
Note table numbers and times.
Avoid making accusations in chat.
Contact the site’s Game Integrity team.
Good reports focus on observable behaviour rather than frustration after losing a pot.
💰 Why Game Integrity Is Becoming a Competitive Advantage
Ten years ago, players mainly compared poker rooms based on traffic, rakeback and bonuses.
Today, there’s another factor that’s becoming just as important: trust.
A poker room can have huge guarantees and attractive promotions, but if players begin to question the integrity of the games, confidence quickly disappears. History has shown that even the biggest operators have had to invest continuously in security as cheating methods evolved.
That’s why leading poker sites now dedicate entire teams to Game Integrity. These departments combine data scientists, security analysts and experienced poker professionals whose only job is to protect the ecosystem.
While every operator keeps many detection methods confidential, several major brands have publicly confirmed that they use a combination of:
continuous behavioural monitoring;
machine learning models;
device fingerprinting;
manual investigations;
financial transaction analysis;
player reports as supporting evidence rather than the primary detection method.
The exact technologies differ from one operator to another, but the direction is the same across the industry: security has become an investment, not just a support function.
For players, this means choosing a poker room is no longer just about finding the softest games. It’s also about finding an operator that actively protects those games.
📝 Final Thoughts
Collusion remains one of the most difficult forms of cheating to detect because it rarely produces obvious evidence in a single hand.
Modern poker sites don’t rely on intuition or isolated player reports. Instead, they analyse enormous volumes of data, combine dozens of behavioural indicators, use machine learning to uncover hidden relationships and then rely on experienced investigators to review each case.
The result is a much more sophisticated approach than most players realise.

❓Frequently Asked Questions
Is collusion the same as using RTA?
No. Collusion involves multiple players cooperating, while RTA involves a player receiving real-time strategic assistance from software.
Can poker sites detect players sharing hole cards?
Not directly, but repeated behavioural patterns consistent with information sharing can be identified through statistical analysis and investigation.
Can two friends play at the same table?
Yes. Playing together is not against the rules by itself. Problems arise only if the players cooperate to gain an unfair advantage.
What is soft play?
Soft play occurs when players intentionally avoid maximising value against one another, often by checking strong hands or avoiding aggressive actions.
What is chip dumping?
Chip dumping is the deliberate transfer of chips from one account to another by intentionally losing pots.
Can collusion happen in cash games?
Yes. It can occur in both cash games and tournaments.
What happens if collusion is confirmed?
Depending on the severity of the offence, poker sites may confiscate funds, permanently close accounts and redistribute money to affected players, according to their policies.
Do poker sites refund affected players?
Many major operators state that, when possible, funds confiscated from confirmed cheaters are redistributed to players who were financially harmed.
Is collusion harder to detect than bots?
Generally, yes. Bots often leave technical fingerprints, while colluding humans can appear perfectly normal in individual hands, making long-term behavioural analysis essential.
