The flashing lights and ringing bells of a casino are designed to distract you, but behind the scenes, a massive accounting system tracks your every move.

Understanding exactly how the casino calculates the value of your comps is the secret to getting the absolute most out of your casino visit.

The Importance of the Player's Card

Every time you insert the card into a slot machine, the central computer meticulously tracks exactly how much money you cycle through the machine.

If you play table games, you must hand your card directly to the dealer or the pit boss before you place your first bet.

• Signing up for a card usually takes five minutes at the rewards desk
• Casinos often give new sign-ups free slot play just for registering
• Losing your card is fine; they will gladly print you a replacement instantly

How Casinos Calculate Your Worth

Casinos do not issue comps based on how much money you actually lost that specific day; they base it on a formula called "Theoretical Loss."

As a general industry standard, casinos will aggressively return approximately 20% to 30% of your total "Theo" back to you in the form of comps.

Working the Casino Comp System

When you first sit down at a blackjack table, immediately place a much larger bet than you normally would to establish a high "average bet."

Finally, always ask the pit boss directly for a comp before you leave the table, such as "Do I have enough action for a buffet pass?"

Treating the casino comp system like a secondary, parallel game is a crucial strategy for any serious, long-term gambler.
