Chip dumping is intentionally losing a hand to transfer chips to another player. That is how PokerStars defines and prohibits it in its rules. This is an operator-specific definition, not a universal legal definition. A losing hand, an unusual decision or a single screenshot does not, by itself, establish intent.
If you suspect chip dumping, preserve objective details and report them privately to the poker operator or tournament staff. Do not turn a suspicion into a public accusation.
How Does Chip Dumping Differ from Bad Play, Soft Play and Collusion?
The key difference between chip dumping and an ordinary mistake is the intention to transfer chips. Collusion means cooperation for an unfair advantage, while soft play is separately addressed by event rules.
| Term | What distinguishes it | What is not enough to establish it |
|---|---|---|
| Chip dumping | Under PokerStars rules, intentionally losing a hand to transfer chips | A loss or transfer of chips alone |
| Bad play | A player can make a poor decision without intending to help an opponent | “I would never have played it that way” |
| Collusion | Under PokerStars policy, cooperation or information-sharing for an unfair advantage | Players knowing each other, sharing a table or making similar decisions |
| Soft play | Conduct specifically addressed by Poker TDA Rule 71, with tournament penalties | One action without context and the applicable rules |
The definitions of chip dumping and collusion appear in PokerStars’ fair-play policy. Avoid treating soft play as strictly “passive” and chip dumping as strictly “active”: the cited sources do not establish that rigid distinction.
Hypothetical example—not a real hand: Player A intentionally loses a hand so that Player B receives the chips. With intent explicitly assumed in this example, the conduct fits PokerStars’ definition of chip dumping. An observer who sees only A’s loss, however, does not know that intent. The visible actions alone do not justify the same conclusion.
An unusual hand, screenshot or isolated statistic may give you a reason to report a concern, but none of these alone proves intent or collusion.
Which Rules and Consequences Apply?
Consequences depend on the poker operator’s rules or the event’s rules. Whether conduct violates local law is a separate question.
- Operator policy. PokerStars prohibits intentionally losing a hand to transfer chips. This is that operator’s prohibition; check its rules for the applicable consequences.
- Event rules. Under Poker TDA 2026 Rule 71, Version 1.0 dated 2026-09-07, chip dumping and other collusion result in disqualification at events that have adopted those rules. Soft-play penalties may include chip forfeiture and disqualification.
- Local law. A rule violation should not automatically be described as a crime. Its legal status depends on the applicable law and circumstances, not simply the name given to the conduct.
Rule 71 also states that checking the exclusive nuts when last to act on the river is not automatically soft play.

Poker TDA is not a regulator. Its rules supplement an event’s house rules, and regulatory rules take precedence. First establish which rules your tournament has adopted.
In a cash game, the relevant poker operator’s rules govern the issue. In a tournament, event rules and the payout structure also matter: a change in stacks can change a modeled estimate of prize-pool equity. That does not mean transferred tournament chips equal the same amount of cash.
How Do You Report Suspected Chip Dumping Responsibly?
Report privately through the operator’s official channel. At a live tournament, contact the tournament director or floor. Describe what you observed without presenting it as proven chip dumping.
Use this reporting checklist:
- Preserve the usernames of the players involved in your concern.
- Include the hand ID and hand history, if available.
- Add the table or tournament ID so the operator can identify where it happened.
- Preserve relevant chat messages if they prompted your concern.
- Describe specific actions: explain what you observed and why you are requesting a review. Separate those observations from assumptions about intent.
- Submit the details through an official channel, rather than publishing private accusations or players’ information.
Usernames, hand histories and hand IDs, suspicious chat, and table or tournament IDs are details PokerStars requests when reporting unfair play. That page describes reporting through its desktop software, app and website. These are PokerStars procedures, not universal instructions for every operator; record availability and interface labels may differ.
At a live event, ask tournament staff how to submit your concern. Decisions are made under the applicable rules, not through public debate about a hand.
What Does the Chip-Transfer Calculator Show?
The calculator models changes in estimated prize-pool equity after a hypothetical chip transfer. It does not detect chip dumping or prove a rule violation.
To use the tool:
- Scroll to the calculator below.
- Set the number of remaining players and the total chips.
- Enter your stack and the prize pool.
- Enter the two other players’ stacks before the transfer.
- Set the hypothetical transfer amount.
- Select one of the three supported payout presets: Standard 50/30/20%, Flat 40/33/27% or Top-heavy 55/28/17%.
- Read the modeled equity before and after the transfer, along with the change.
The tool uses the Malmuth–Harville Independent Chip Model (ICM) for the top three places. All players other than you and the two specified players are assumed to hold equal shares of the remaining chips. It cannot model arbitrary payout structures or arbitrary stack distributions among the other players.
The calculator cannot inspect hands or player accounts, infer intent, detect or prove cheating, confirm collusion or establish actual damages. Its monetary output is only a model estimate under the stated assumptions.
Hypothetical inputs shown in the interface capture—not an observed event: 9 players; 135,000 total chips; your stack 15,000; the two specified players’ stacks before the transfer 12,000 and 18,000; transfer 8,000; prize pool $10,000; Standard 50/30/20% payouts. The six other players are assumed to hold 15,000 chips each.
Under these assumptions, your modeled prize-pool equity changes from $1,112.19 to $1,125.85: +$13.66; +1.23%. The transferring player’s modeled equity changes by −$586.04, and the recipient’s by +$490.41. Monetary values are rounded to cents. These results are not actual payouts or proof of anyone’s losses.

Frequently Asked Questions
Chip dumping is intentionally losing chips to another player through deliberately bad play. The 'dumper' makes obviously losing bets or calls to transfer their stack to the 'receiver' who is typically a friend, partner, or second account.
Chip dumping itself is against the rules of every poker room but not always a criminal offense. However, when used for money laundering it violates federal anti-money laundering laws (Bank Secrecy Act) and can carry prison sentences of up to 20 years.
Online poker sites use AI algorithms that analyze hand histories for suspicious patterns: always folding to a specific player, making irrational calls, consistent chip transfer between accounts, shared IP addresses, device fingerprinting, and statistical win-rate anomalies.
Consequences include permanent account ban, confiscation of all funds, being added to industry blacklists, and potential criminal prosecution. At live tournaments, players face disqualification, forfeiture of prizes, and multi-year bans from the circuit.
Yes. In cash games, chip dumping is commonly used for money laundering (clean money in, dirty money out) or bonus abuse (creating action to clear deposit bonuses). The chips go directly to cash, making it a simpler transfer mechanism than tournaments.
Soft play means going easy on a friend — checking when you'd normally bet, not raising a strong hand. Chip dumping is intentionally LOSING chips through bad play. Soft play is unethical but passive; chip dumping is active and deliberate cheating.
Chip dumping artificially inflates the receiver's stack, increasing their ICM equity at everyone else's expense. Even if you're not involved, a 10,000-chip dump at a final table can cost you 2-5% of your tournament equity — hundreds or thousands of dollars.
In 2025, players Rob Carroll and Yuki Yaginuma were accused of chip dumping at a WSOP event. The case drew attention because of suspicious hand histories showing a pattern of one player consistently making unprofitable plays that benefited the other.
Yes, and this is one of the primary reasons it's taken so seriously. Player A buys in with dirty money, intentionally loses to Player B, and Player B cashes out 'clean' winnings. Casinos are required to file Suspicious Activity Reports (SARs) when they detect this pattern.
While exact numbers are hard to pin down, major poker sites report catching thousands of colluding accounts annually. PokerStars alone has confiscated millions in funds from detected cheating rings. Multi-accounting makes online chip dumping easier but also more detectable.
One person creates multiple accounts, sits at the same table, and dumps chips from their 'sacrifice' accounts to their main account. This is the most common form of online chip dumping and also the easiest to detect through IP and device tracking.
Absolutely. Online sites have dedicated security teams — email their support with hand numbers, player names, and timestamps. At live tournaments, report to the floor manager or tournament director immediately. Providing specific hand details helps investigations.
Technically yes, but it's extremely obvious in heads-up because there's only one opponent to transfer to. Chip dumping is more effective and harder to detect at full ring or multi-table tournaments where the transfers can be disguised among many hands.
Professional security teams use statistical analysis of win rates between specific player pairs, Benford's law analysis on bet sizing, network analysis of fund transfers, and machine learning models trained on known collusion cases. Our ICM calculator above helps quantify the impact.
Yes. Transferring chips outside of normal gameplay — whether physically handing them over or through arranged hands — is chip dumping. Even buying chips from another player between hands is against the rules at every regulated poker room.
