AML (anti-money laundering) is the anti-money-laundering rulebook that obliges a casino to know who its client is and where their money comes from. A licensed operator has to run risk-based monitoring — a no-KYC casino does it too, just in the background and later: the account opens quickly and anonymously, but the check can trigger when money starts to move out.
When the check triggers. The three usual triggers are large cumulative turnover, a sudden change of pattern (a quiet account suddenly makes an unusually large deposit) and a random sample. Operators rarely publish exact thresholds and they differ by licence — the Curaçao licence sets minimums, the rest is decided by the casino's own risk policy.
What is asked for. Usually an identity document and a selfie, and for larger amounts also proof of the origin of funds: a salary certificate, an exchange statement or transaction IDs. The withdrawal sits until the check is complete — it cannot be cancelled, sped up or redirected to another address. That is why one slow withdrawal does not always mean a bad casino.
What to check:
- whether the terms state at all when and which documents are requested;
- whether a deadline is set for the check or it is left open;
- whether support answers substantively when you ask for the document list before the first withdrawal;
- whether your own paperwork exists — exchange statements and transaction IDs are worth keeping from the first deposit onwards.
If proving the origin of funds drags on, so does your money. In every review in the ranking we look at whether the document demand matched what the terms promised; the technical steps around deposits and withdrawals are set out in the payments overview and the network-side waiting under the term confirmation.
Three stages: how the check works at a casino
First, customer identification: the casino identifies you when you open an account or before your first withdrawal. Second, ongoing monitoring: transactions, addresses and play patterns are watched all the time. Third, reporting suspicions: if the casino sees a reason, it notifies the financial intelligence unit (Rahapesu Andmebüroo, FIU). In general the operator may not tell you that a report was made. The framework comes from EU anti-money-laundering directives, see Directive (EU) 2015/849, and from each member state's laws. The exact obligation depends on the licence the casino holds.
What is specific to a crypto casino: address and origin
The blockchain is public, so an operator can examine where your deposit came from. Funds whose history passes through mixing services, sanctioned addresses or stolen assets can raise suspicion, and a withdrawal is held. Send funds from an exchange account in your own name and keep the transaction ID so you can show where it came from if needed. You can review your own transaction history in a block explorer. A related requirement is described under travel rule.
Common mistakes
- Depositing from someone else's exchange account or wallet: the name does not match, and that is a usual reason why a withdrawal stalls.
- Splitting a large amount into many small deposits to avoid checks. Such a pattern stands out in monitoring rather than disappearing.
- Ignoring document requests or sending incomplete documents. The review then stays open.
- Assuming that "no-KYC" means "no AML", see no-KYC and no-KYC casinos and Estonian law.
For document requirements see also the explanation of the KYC threshold. The reasons for withdrawal delays at Estonian casinos are explained by the KYC check before a withdrawal.
