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.
Tracking Your Casino Action
The single biggest mistake any casino visitor can make is choosing to gamble without signing up for a free player's rewards card.

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.
Never gamble a single dollar without inserting your player's card firstThe card tracks your "coin in," not just your deposits or lossesTable game players are rated based on average bet and time played Understanding "Theoretical Loss" (Theo)
Theoretical Loss, commonly referred to as "Theo," is the exact mathematical amount the casino expects to win from you over time.

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
The pit boss usually only records your initial bets; once they walk away, you can quietly lower your bet size back to normal.

Furthermore, taking frequent bathroom breaks or talking on your phone slows down your hands per hour while the pit boss still clocks you as "playing."
