Video poker is a casino game derived from poker that follows the same rules as regular poker. The main difference between the two games is that in video poker, you play against a computer instead of other players.
The rules of the mobile video poker version are essentially the same as a regular video poker game. To play, you select the amount of money you want to bet, and place it on the table following the instructions of the game.
Next, you are given 5 cards face up. After reviewing your cards, you can either keep all of them, some of them, or none of them. When you discard cards, the computer will replace them with different ones.
Finally, depending on the combination you have on your final 5 cards, you will receive a payout. In the case of video poker, you can either get a standard payout or a special bonus from getting a certain combination of cards.
