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.
Why You Must Always Use a 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 the casino cannot track your action via this card, you simply do not exist in their system, and you will receive absolutely zero comps.

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."

If you wager $10,000 on a slot machine with a 10% house edge, your "Theo" is $1,000, regardless of whether you won or lost the session.
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?"
