Closed loop: back the way the money came

Closed loop (return to source) is the rule that money is withdrawn by the same method it was deposited with, up to the amount deposited. This stops the casino becoming a transit point for money laundering, and the player gets the payout back where they paid from.

How it works

The cashier remembers the method of every deposit. On withdrawal, the money goes back to those methods first, up to the amounts deposited through them. Winnings above the deposits go to a verified bank account or e-wallet in the player's name.

Withdrawal to a method = no more than the deposits made through that methodFor example, a player deposited €300 by card and €200 by e-wallet and withdraws €1,000: €300 goes to the card, €200 to the e-wallet and €500 to their bank account.

Why the rule exists

Without it, a casino can be used as a money exchange: deposit money from someone else's or a stolen card, barely play and withdraw to your own account. The rule shuts this scheme down: it is a basic AML measure and a safeguard against fraud. It is usually required by the licence and by payment providers.

Exceptions and the cashier

Not every method accepts payouts: vouchers, for example, and some prepaid cards and local methods are deposit-only. In that case the money goes to the player's bank account or e-wallet verified during KYC.

Explain the rule in the cashier before the request, in one line next to the amount: "€300 will go back to the card you paid with, the rest will be sent to your account". A player who knows in advance where the money will go writes to support less often and does not argue about the payout method.

Common mistakes

  • The rule is visible only after the request. The player chose the e-wallet, but the money went to the card. The rule is right, but the complaint is already in.
  • No fallback for deposit-only methods. The request sits there while support works out by hand where to pay. The player names a fallback account in advance.
  • Exceptions without checks. A withdrawal to a new account without a name check opens up the very scheme the rule protects against.
