US Patent 8371921 Keno game with poker hands using deterministic card placements

A method, apparatus, and computer readable storage to implement a wagering game combining keno and poker. A first payout is made based on a number of matches between player selected numbers and computer generated numbers on a keno grid. Card values are also associated with each number in the keno grid. The card values are determined using a deterministic hashing algorithm. Then, for each matched number, the best five card (or any other predetermined number of cards) poker hand is made using the associated card values, and a payout is made (if earned) based on a rank of the best poker hand.
