Comps are complimentary items and services given out by casinos to encourage players to gamble. The amount and quality of comps that a player is given usually depends on what game(s) they play, how much they bet, and how long they play.
Most casinos have casino hosts responsible for awarding comps and contacting players to bring them back to the casino. Pit bosses can also award comps at table games. Most casinos ask players to get a player's club card so their play can be tracked and comps awarded accordingly.
The second level of comp is free self-parking, lounge access, or free meals. Many casinos have several players' lounges and restaurants and might require more play to earn a comp to higher-end restaurants. Often the player is given a certain amount to spend, but sometimes high rollers might get to order as much food as they want and bring guests.
The next level of comps is free lodging, free valet parking, and free access to more exclusive high roller lounges. Many casinos have attached hotels, but those that do not can sometimes comp rooms to a hotel nearby. Many casino hotels have better rooms, such as suites, villas, and presidential suites for bigger bettors. Many players who get hotel rooms also get a package called "RFB" (for "room, food, and beverage") or "RF" (for "room and food").
Many casinos also offer other comps, especially to high rollers. These can include airfare, limo rides, show tickets, golf, concierge services, cash back, loss rebates, private gaming areas, and private jet service.
Casinos also often offer players comps by mail, email, or app. These can include free bet offers, free meals, discounted or free rooms, tournament entries, or prize drawings. These offers often come with terms and conditions for rollover and wagering requirements.
Some casinos contract with bus companies to bring players. Riders often enjoy free slot play and dining coupons often worth as much as the bus fare itself.
Technically, every player may be offered comps, but most casinos require players to have played for a given period of time and at a certain level; the duration of play and amount wagered are directly proportional to the level of expected comps. Which games are played are also factors. Casinos award comps based on a player's Average Daily Theoretical loss (known as ADT, theoretical loss, or "theo").
- Theoretical Loss = (Casino Advantage) × (Total Wager)
"Comp counters", "comp hustlers", or "comp wizards" try to maximize comps while minimizing expected losses. Comp hustlers play games with a low house edge, such as blackjack or video poker, or games with small bet sizes, such as penny slots. Comp hustlers use tactics such as placing large bets when a pit boss is checking their bet size to rate them for comps and then moving to a smaller bet size when the boss is not watching. They also take frequent breaks from playing, play at full tables to be dealt fewer hands per hour, and play more slowly.
Comp hustling is a type of advantage gambling when the player hustles more in comps than their average losses. And the author of "How to Get a Dollar in Casino Comps for Every Dime You Lose Gambling", in their summary of key takeaways from Max Rubin's book, Comp City, observes: "The next step up from being a comp wizard is to become a comp counter. These players have specific knowledge and skills that enable them to combine a low house edge with comps in order to profit." Another step up are practitioners of "ACES (Advanced Comp Earning System). People practicing this kind of system earn a dollar's worth of comps for every dime they lose gambling."
Online casinos, poker rooms, and sportsbooks offer bonuses similar to brick and mortar casino comps. Comp hustlers and advantage players can use these bonuses to turn a profit via bonus hunting or can convert these comps to a guaranteed profit using matched betting.
Online casinos know of the potential for losing money while giving out bonuses. Casinos have minimum wagering requirements as a result.
Some casinos limit the payout in case of a win. They also sometimes restrict players from playing games with a low house edge.
