When learning how to be a Las Vegas casino Pai Gow Poker dealer, the first step is to learn the hand rankings. Study the chart below and note two differences between Pai Gow Poker and standard poker rankings. First, Pai Gow Poker includes a joker. The joker either an ace or it completes a straight or a flush – it is not wild. Also, the highest possible straight is A-K-Q-J-10. But unlike poker, the second highest straight in Pai Gow Poker is 5-4-3-2-A.
