### REPLY:
The most common methods used for money laundering in illegal gambling operations include smurfing, where large amounts of cash are divided into smaller deposits to avoid suspicion, using shell companies to layer the funds and make them appear legitimate, and utilizing online payment systems with lax regulations to transfer and disguise the illicit money. Additionally, some criminals use casinos and gambling establishments to convert the illegal proceeds into legitimate winnings, which can then be withdrawn as clean money.
