Below are probability tables for two versions I have seen based on a single deck game. The following table displays the house edge for each version given the number of decks used. In the unlikely event you ever see version 2 at a table with 4 or more decks be sure to play it hard because the player will have the advantage. At the Isle of Capri casino in Natchez, Mississippi, they use version 1 of the royal match with 6 decks. The probabilties for the royal match are easy to derive.
Lets use n for the number of decks of cards.
This is because there are 4 suits and n ways to choose the queen and n ways to choose the king. You must also subtract the number of ways to make a royal match. Streak Streak is an optional blackjack side bet I noticed at Caesars in Atlantic City in April of 2000. This is a simple bet on winning a specified number of consecutive bets. If the player split it is the net win that counts toward whether the hand as a whole won or lost.
