51. Gaming Day

Financial Transactions

A gaming day is the 24-hour period used by a casino for business, accounting, and regulatory purposes, including the aggregation of currency transactions for CTR reporting. The gaming day is a defined period (e.g., 3:00 AM to 3:00 AM) chosen by the casino, typically ending during the slowest business hours to minimize disruption. All of a patron’s currency transactions — chip purchases, redemptions, front money deposits, marker payments, currency exchanges — are aggregated within a single gaming day to determine if CTR reporting thresholds ($10,000) are met. A casino may have only one gaming day, which must be common to all gaming operating divisions. On December 31, all gaming days must end by 11:59 PM to close the calendar year.

In practice

FinCEN defines gaming day as “the normal business day of a casino” — it is not a rolling 24-hour window. Casinos must clearly define and consistently apply their gaming day in their internal controls.
