Short for Advantage Player.

A mathematical theorem that states, for any set of independent random variates with finite variance, that the cumulative distribution function of a normalized (scaled) sum of such variates approaches the cumulative distribution function for a normal distribution, as the number of variates increases. Under certain circumstance, the theorem states that the width of the central region of the associated probability distribution function narrows, and approaches zero, as the number of random trials (variants) increases and that the shape (of the central region) of the PDF approaches a normal PDF as the number of trials increases. If all variates are from a single uncorrelated random process, the theorem states that variance decreases as 1/sqrt(n) where n is the number of trials. Since each video poker hand is independent of all other hands, and since video poker's variance is finite, The Central Limit Theorem holds for all video poker, and the variance scales as 1/sqrt(n), where n is the number of hands. However, at the same time, the total bet or coin-in has been increasing proportional to n. Thus the variance in real units (dollars) increases without limit as the player continues to gamble.

Defined as one over the probability of receiving a certain hand or payout. In video poker, the Cycle is therefore expressed in units of hands (or deals). Perhaps because of this, the term Cycle is commonly misused and many players erroneously expect to receive a certain hand once per cycle. A cycle represents the number hands it will take on average for a certain outcome. A player may of course receive any number of such hands in a cycle (from 0 to the cycle length).

Referring to the missing card or cards in an inside straight. When there is one missing card, it is a single Gap and when there are two, it is a double Gap. A double Gap inside straight can produce only a single straight. One the other hand a single Gap three card inside straight draw can produce up to three different straights. Often a terminal single Gap inside straight draw (a hand containing an ace) is treated as a double gap since only one straight can be drawn.

Poker hand comprising the ten, jack, queen, king and ace of one suit (in any order). For most draw video poker games, the probability of a natural (no wild card) Royal Flush is approximately 1/45,000. For example:

The period of time a casino considers a single gaming day. Typically, the Slot Day day differs from the normal day and typically begins early in the morning rather than at midnight (perhaps to correspond with a shift change). The Slot Day is used (not the date) for comp rating purposes. At many casinos, the date on the W2-G is also based on the Slot Day, so that a jackpot won just after midnight on New Years is reported for "last year"

A video poker game in which the wagering of a sixth coin (assuming the base game is a five coin max game) triggers a new mode that gives the player a bonus whenever there is a (natural) four of a kind. The average bonus is approximately 428 units, and it increases the return (relative to the base game) of all video poker games except for (most) wild card games, such as Deuces Wild. The Wheel Poker feature increases the variance of games and necessitates strategy changes to achieve the best return.
