21+3 Blackjack is a very popular side bets blackjack variation, invented and patented by Derek J. Webb in 2000. The game is a combination of blackjack and three card poker, where your first 2 cards and the dealer’s face up card are used to combine a three card hand. If you are familiar with Perfect Pairs, then you can look at 21+3 as its further development.

1. The odds of being dealt a Blackjack are 4.8%. In a game involving multiple players, the round begins with the person to the left of the dealer as the first to act, then play goes clockwise.
2. Insurance is a sucker bet. You are betting that the dealer has a ten-value downcard to go with her Ace upcard (thus giving her a blackjack). A winning insurance bet pays 2-1 but the odds of winning are worse than 2-1. In that particular situation, even if you have a blackjack, and the dealer offers you even money, decline it.
3. Single deck blackjack has the lowest casino edge of 0.16%, which gives the player better odds. Double deck games have a considerably low edge at 0.46%. Most land-based resorts and reputable online casinos use six to eight decks for blackjack.

It is considered one of the latest additions and therefore it is not offered by most blackjack sites. Nevertheless, there are 3 versions of 21+3 Blackjack available online and we are sure that more to come.

The third game that the Wizard has reported on thus far is Swiss Casinos Jack, which pays out when players get a blackjack. The game pays out for a Jack is Black (the Jack in the blackjack is a black card) at a rate of 50:1, All Red (both blackjack cards are red) at 25:1, and regular blackjacks at 10:1 if you take the sidebet.
