How Casinos Track Player Activity And Preferences

When you walk onto a modern casino floor, you are stepping into one of the most heavily monitored environments on earth.


Every single wager you place, every drink you order, and every hotel room you book is carefully logged into a massive database.

This data calculates your 'Theoretical Loss' (often called 'Theo'), the exact mathematical amount the casino expects to profit from your session.
