The dealer will deal out 2 cards, one on the left and one on the right. In order for the player to win, the third card's rank must come between the other two cards' rank. So if the two cards are a 5 and a Jack, a winning hand would consist of a card between a 6 and a 10. The closer the two cards are in rank the higher the pay out.
Before the player sees the third card, he has the option of doubling his bet by clicking on the raise button. A push happens when the first two cards dealt are either consecutive or are a pair. If the third card dealt makes three of a kind then the player is paid out at 11 to 1.
