Video poker machines in Las Vegas are considered “fair” in the sense that they are subject to state regulations requiring them to deal random cards from a 52-card deck (plus a joker, when applicable). The gaming authority periodically checks the machines.

A common variant is called “Deuces Wild” in which deuces can be a wild card, and the jackpot is paid for four deuces or a true (not wild) royal. Another includes a “bonus” schedule for a hand like “four aces with a kicker of 5 or more.” Another variation allows multiple playing, where additional hands can be played from a “deck” where the first hand’s cards have been removed.

The most common form of video poker still is “Jacks or Better,” in which payoff start with a pair of jacks or better (at 1:1) and go up from there. To be eligible for the maximum jackpot on a quarter or dollar machine, it is necessary to bet the maximum of 5 bets or credits each time. Otherwise, a bet of more than one coin but less than 5 will just multiply the jackpot by that number. It is the extra jackpot for the 5th coin that improves the edge for the player. Professionals always bet the maximum amount, as it always makes the edge more favorable to the player.

The following table compares a typical payoff for a “9-6-250” flat top of “Jacks or Better” with a typical “Deuces Wild” payoff schedule.

Video Poker machines in Las Vegas also vary by where the casinos are located. Off-strip casinos often cater to a “local” crowd and offer machines with somewhat more generous terms – even positive expectation machines. In general, strip casinos provide video poker with a more substantial house advantage.
