Ultimate 21
Introduction
Ultimate 21 is a simple blackjack variation requiring no skill, except bet selection. I have seen it at the Sahara and Hard Rock casinos in Las Vegas but both have removed it.
Rules
A five deck shoe is used, usually from a continuous shuffler.The dealer will deal four cards and form the best possible blackjack hand that can be composed using any number of the four cards. The player bets in advance what the highest total will be.
For example if the four cards are a 5, queen, 3, and 4 the best total would be 19. The following table shows what each bet pays.
