To play video poker, first, select the game you want to bet on. Then choose the number of coins you want to bet and press the "Deal" button. You will be dealt five cards, and you can choose which cards to keep and which to discard. After you have discarded all the cards you don't want, press the "Deal" button again, and you will be dealt replacement cards. Once you have the last hand, the machine will make a payout depending on the strength of your hand.
