*
* Short Description and Poker rules:
*
* Video poker is also known as draw poker.
* The dealer uses a 52-card deck, which is played fresh after each playerHand.
* The player is dealt one five-card poker playerHand.
* After the first draw, which is automatic, you may hold any of the cards and draw
* again to replace the cards that you haven't chosen to hold.
* Your cards are compared to a table of winning combinations.
* The object is to get the best possible combination so that you earn the highest
* payout on the bet you placed.
*
* Winning Combinations
*
* 1. One Pair: one pair of the same card
* 2. Two Pair: two sets of pairs of the same card denomination.
* 3. Three of a Kind: three cards of the same denomination.
* 4. Straight: five consecutive denomination cards of different suit.
* 5. Flush: five non-consecutive denomination cards of the same suit.
* 6. Full House: a set of three cards of the same denomination plus
* a set of two cards of the same denomination.
* 7. Four of a kind: four cards of the same denomination.
* 8. Straight Flush: five consecutive denomination cards of the same suit.
* 9. Royal Flush: five consecutive denomination cards of the same suit,
* starting from 10 and ending with an ace
*
