According to the Anti-Money Laundering Specialist (the 6th edition) resources, the situation that is the highest risk for money laundering and terrorist financing activity is A. A customer purchases casino chips, using small denomination bank notes, but does not engage in game play before redeeming the chips for a casino check. This is because this situation may indicate some red flags of money laundering, such as:

Using small denomination bank notes, which may be an attempt to avoid detection or reporting by the casino or the authorities, as large amounts of cash are usually associated with criminal activity1.

Not engaging in game play, which may indicate a lack of interest in gambling and a sole purpose of exchanging cash for a casino check, which is a more legitimate and less traceable form of payment2.

Redeeming the chips for a casino check, which may be a way of laundering the cash through the casino, as the check can be deposited into a bank account or cashed at another location, without revealing the source of the funds3.

The other three options are less risky because:

B. A customer purchases casino chips and engages in significant game play before requesting a casino check for the remainder is less risky, as it may indicate a genuine interest in gambling and a legitimate source of funds. However, this situation may still require further investigation and verification, as some money launderers may use gambling as a cover for their illicit activities, or may use the casino check as a way of transferring funds to another jurisdiction or person4.

C. A customer purchases casino chips using a credit card and engages in minimal game play before redeeming the chips for a casino check is less risky, as it may indicate a low level of funds involved and a traceable source of funds. However, this situation may still require further investigation and verification, as some money launderers may use credit cards to obtain cash advances from the casino, or may use the casino check as a way of repaying their credit card debt or transferring funds to another jurisdiction or person.

D. A customer purchases casino chips using credit from an account at an affiliated casino and engages in significant game play before redeeming the chips for a casino check is less risky, as it may indicate a regular and loyal customer of the casino and a legitimate source of funds. However, this situation may still require further investigation and verification, as some money launderers may use credit from an affiliated casino to avoid carrying cash or using credit cards, or may use the casino check as a way of transferring funds to another jurisdiction or person.
