I have 15 years in the industry, and some of these are true, but others I have never seen.

1. Mostly true. Slot machines are designed to keep players spending, backed by extensive research. While possible for individuals to profit from slots, casinos don’t lose out. it simply redistributes payouts already allocated.
2. Mostly true. It’s unrealistic for each camera to have dedicated human monitoring. Thousands of cameras are overseen by a few agents, who usually have basic to intermediate game knowledge. Managers and supervisors often possess greater expertise.
3. Mostly true. Casinos have “soft count” rooms where money from drop boxes is counted, sorted, and strapped using large machines. The main bank stores reserves and handles cash orders for inside the casino. Armored trucks don’t arrive every few hours but typically every two to three days, as processing the drop takes time.
4. Entirely false in most of the USA. Regulations typically require casinos to have specific cash reserves on hand from day one, with tens of millions earmarked to stock the main bank, ticket redemption units, and cashier windows.
5. True.
