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 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 algorithms differ by casino, but the logic behind the calculation generally works like this: Theoretical Loss = (Casino Advantage) × (Total Wager) Comp hustling "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. Online comps 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 and 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. References Gambling terminology
