Video Poker is a game that combines slots and 5 stud poker game. The invention of the game was possible in the late 1970's during the invention of the personal computer that allowed combining video technology with a monitor that would display the game.
The game itself is a 5-reel slot machine model that uses a standard 52 cards deck. The symbols of the 52 cards are scattered along the reels and lines and the objective of the game is to hit the highest possible 5 stud poker hand with every spin.
There is a fixed pay table that indicates the payout for each type of poker hand the video poker machine hits. The less common the hand is; the higher is the payout and the game follows the standard poker hand hierarchy with a pair being the lowest hand and a royal flash being the highest hand as it is the rarest.
Over the years several video poker variations have developed and today each online casino tends to offer many variations of the game. They all follow the same poker hands principles and tend to be different only by the fact the each variant might have additional hands as winning hands such as jokers as wild cards and payout more for hands that include them.
