Abstract
Abstract A slot machine having five rotatable reels, each bearing on its outer periphery symbols of at least twelve different playing cards consisting of at least three cards of each suit and four out of 20 different cards consisting of the aces, tens and face cards of a deck of playing cards, and with spot cards numbered two through nine. Combinations of cards are displayed in horizontal rows at random during each game, and prizes are awarded when prize-winning combinations of cards corresponding to specified hands suitable for melding in a poker game occur on prize-winning rows previously selected. For selectively discarding any of the cards of an occurring combination, the slot machine is provided with pushbuttons which restart the rotation of a selected reel or reels.
