advantage

Advantage gambling, or advantage play, refers to legal methods used to gain an advantage while gambling, in contrast to cheating. The term usually refers to house-banked casino games, but can also refer to games played against other players, such as poker. Someone who practices advantage gambling is often referred to as an advantage player, or AP. Unlike cheating, which is by definition illegal, advantage play exploits innate characteristics of a particular game to give the player an advantage relative to the house or other players. While not illegal, advantage play may result in players being banned by certain casinos.
A skillful or knowledgeable player can gain an advantage at a number of games. Card games have been won by card sharps for centuries. Some slot machines and lotteries with progressive jackpots can eventually have such a high jackpot that they offer a positive return when played long term, according to gambling mathematics, though this requires often difficult to acquire information about the settings of the specific slot machine and specific casino, a knowledge of statistics and probability, as well as a large enough bankroll to withstand the inevitable volatility. Some online games can be beaten with bonus hunting.
