Definition: The word comp means complimentary and is the term used for the rewards that casinos give to players for gambling in their property.
Comps are a reward for your average daily theoretical loss (A.D.T)
Comps are one of the most misunderstood aspects of Las Vegas. Most players believe that comps are only for high rollers, who spend thousands of dollars each day. But this is not true.
There are different levels of comp, depending on how much play you give the casino. Most players can usually get something for their play if they have played in the same casino for a decent amount of time.
Players Programs & Slot Clubs: To be eligible for comps, the first thing you need to do is sign up to the casino players club. This is always free to join and you often will be rewarded with free slot play or meal vouchers just for signing up.
Ensure you use your player's card whenever you play slots or video poker. When playing table games, hand your card to the dealer
Getting Comps: The easiest way to obtain comps is to just ask. If playing slots, ask a slot an attendant to call a casino host and if playing table games, the pit boss will call one for you.
When the casino host comes over simply ask them politely if your play qualifies for food, show tickets or a reduced room rate.
A low level player will never be approached by a host, but you may be surprised what you can get just by asking.
Before you checkout, always call the front desk or ask to be connected to a host and ask whether you are eligible for a reduced room rate. Several properties will now do this for you when you are at the checkout desk, but it is still best to call ahead.
So, be bold and ask for a comp, but be polite about it. Las Vegas has enough douche bags. Remember to tip the host if they help you out. Its a relationship that is worth building on, as they will help you in the future.
