In the context of casinos, comps are complimentary items and services given out by casinos to encourage players to gamble. The amount of comps that a player is given usually depends on what game they play, how much they bet, and how long they play. Most casinos have casino hosts who are responsible for giving out free items and contacting players to bring them back to the casino. Pit bosses can also award comps at table games. Most casinos now require a player to have a player's club or similar card, so that their play can be tracked and comps awarded. Most casinos give away promotional merchandise or "swag" just for standing in line.
The second level of comp that many players earn is free meals. Many casinos have several restaurants and may require more play to earn a comp to the higher-end restaurant. Often the player is given a certain amount to spend, but sometimes, particularly with high rollers, the player may be given the right to order as much food as they want.
The next level of comps is usually free hotel rooms. Many casinos have attached hotels, but those that don't may have the ability to comp rooms to a hotel nearby. Many casino hotels have higher quality rooms, such as suites, villas, presidential suites and so on for bigger bettors. Many players who receive hotel rooms receive a package called "RFB" for "room, food, and beverage" or "RF" for smaller bettors, or jurisdictions where casinos are not allowed to give free alcohol.
Many casinos also offer other comps, especially to high rollers. These may include airfare reimbursement, limo rides, tickets to shows, golf, free concierge services, cash back, money to show up in the casino, loss rebates, private gaming areas, and private jet service.
Casinos also frequently offer players comps by mail. These may be free bet offers, free meals, discounted or free rooms, or entries into tournaments or prize drawings.
How comps are calculated
Casinos award comps based on a player's theoretical loss, or "theo" for short. The theoretical loss is the amount of money a player is expected to lose based on the long run statistical advantage the casino has on the particular game being played.
Theoretical loss is calculated as follows:
Theoretical Loss = (Casino Advantage) X (Total Wager)
There are players, known as comp hustlers, who attempt to maximize the amount of comps that they receive, as well as minimize their expected losses in gambling to receive those comps. Comp hustlers play games with a low house advantage, such as blackjack or video poker, or games with small bet sizes such as penny slots. Comp hustlers may 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 may 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.
Online casinos, poker rooms and sportsbooks offer a variety of bonuses that are similar to brick and mortar casino comps. Like with comp hunters, these bonuses can similarly be used by advantage players to turn a profit via bonus hunting, or can be converted to a guaranteed profit using the technique of matched betting.
