21+3 Blackjack is an unusual version of online blackjack with the elements of Three Card Poker. The author of the game is Derek Webb, who invented this type of poker.
Six standard 52-card decks are used in 21+3 Blackjack. Jokers are not provided. All cards are shuffled before each deal.
It is possible to make two kinds of bets in 21+3 Blackjack. The basic bet is a traditional wager for blackjack. The player who has made it should beat the dealer, gaining a higher score without exceeding twenty-one.
If you make this kind of bet, there are the following rules:
Ordinary winning boxes are paid 1:1. The payout for blackjack is calculated according to the 3:2 ratio. Insurance is paid 2:1.
Side bets are made on the additional field. The first two-card hand and the dealer's upcard are considered for this wager. If this three-card hand has a paid combination, the customer immediately receives a payout of the established size.
There are the following winning hands (with multipliers):
Let's briefly discuss the gameplay in the case when the customer makes both bets (they may be of different sizes). The croupier deals one card to himself and two cards to the player. If a three-card hand on the table has a paid combination provided in Three Card Poker, the payout is credited.
The customer decides what to do with his or her two cards according to the rules for blackjack. It is possible to hit, stand, split, or double. In general, everything looks like in the traditional blackjack.
According to the company, the theoretical payout percentage of 21+3 Blackjack reaches 99.7%.
