Increasing competition in the online gambling market is forcing online casino software developers to come up with more and more new ways to attract customers. One of the popular methods is to develop original models by merging time-tested games of chance.

In this review from the site, we will discuss 21+3 Blackjack ("Blackjack 21+3"), which is offered to users by IGT. The game combines the principles of classic European blackjack and three-card poker.

Blackjack 21 3 rules

21+3 Blackjack is an unusual type of online blackjack, which contains elements of three-card poker. The author of the game is Derek Webb, who once invented this type of poker.

For 21+3 Blackjack, six standard decks of fifty-two sheets each are used. There are no Jokers here. All cards are shuffled before each deal.

In 21+3 Blackjack you can place two bets. The main bet is a regular blackjack bet. The player who made it seeks to beat the dealer by scoring more points than him, without exceeding twenty-one.

At this rate, the game is played based on the following rules:

The dealer draws a card at sixteen and stops at any seventeen.

The dealer initially deals one card to himself, which he places face up.

A double is allowed on any two cards.

Split and re-split on the box are allowed.

A double can be done after a split.

One card is dealt to the split aces.

There can be no blackjack on split boxes.

There is no surrende in 21+3 Blackjack.

There is insurance against blackjack with an open ace from the dealer.

Regular winning box pays 1:1, blackjack - 3:2, insurance - 2:1.

A side bet is made on an additional field. According to it, the first two cards of the player and the dealer's card opened from the distribution are played. If these three cards have a paid combination, the client immediately receives a payout of the set amount.

The following combinations are considered winning (with payout coefficients):

• Flush - 5:1

• Street - 10:1

• Tris - 33:1

• Straight flush - 35:1

• Tris of the same suit - 100:1

You can play 21+3 Blackjack only on one box. In Mr. Green Casino both rates are accepted in the range from one to a thousand credits.

The theoretical return of 21+3 Blackjack as specified by the manufacturer is 99.7%.

Let's briefly consider the course of the game in the case when the client makes both bets (they can be of different sizes). The dealer deals one card to himself and two cards to the player. If three cards on the table contain a payable combination of three-card poker, the winnings are accrued on it.

The client then decides what to do with his two cards, following the rules of blackjack. He can, depending on the situation, take another card, stop the set, split or double the bet. In general, everything is the same as in regular blackjack.
