Blackjack Super 21

Also called '21', Blackjack online comes in many variations, but the rules are all very similar and easy to follow. You challenge the dealer to see who can get a hand value closest to 21 without going over that number. If hand value exceeds 21, it is called a Bust and the opponent wins. In online Blackjack rules, each card has a point value. Play Free Online Blackjack. Counting to 21 has never been more fun with the adventures of Blackjack. Blackjack is one of the most popular card games in the Casino industry. One of the reasons is because Blackjack has one of the best odds of winning and doesn't the strong house edge as other card games do.

Blackjack Super 21 is a multi-hand blackjack variant played with 6 decks and according to the traditional rules – players win if their hand has a higher value than the dealer’s but does not exceed a total of 21. The payout rate for natural Blackjack hand is lower than the standard 3:2 unless the hand is suited.

Game Rules & Features

Blackjack Super 21 allows the player to bet on 1 - 5 hands at the same time – to start the session, one must submit at least one Ante bet and click on the “Deal” button. After the cards are drawn from the shoe, the following options will appear on the screen:

  • Hit – request an extra card to be drawn from the shoe and added to your hand. Players can request multiple cards, except after doubling or splitting Aces, in which case only one extra card will be dealt (or one per each Ace, when split). If you hit 6 times without busting, 6-Card Charlie rule will be applied, and the hand will win automatically – even if the dealer has a natural blackjack (a 10-value card and an Ace).
  • Stand – request no additional cards and challenge the dealer
  • Split – separate the cards that have the same value and play them as two individual hands. Re-splitting is not permitted.
  • Double – raise the Ante and draw a card. Doubling will limit the Hit option to just one more card, after which the player must Stand.
  • Insurance – a side bet offered if the dealer’s up card is an Ace; if the players decide to take the Insurance, 50% of the Ante will be added to the initial bet.
  • Surrender – forfeit half of the Ante bet if the dealer’s up card is strong. Dealer must stand on 17 or draw on 16 and the player’s natural Blackjack always win.

Payouts & RTP

The average RTP percentage rate of Blackjack Super 21 is 99.22% and the highest payout rates (2:1) are awarded for:

  • Ace of Diamonds with a matching-suit 10-value card
  • 6-card hand with a 21 total

The Insurance bet is also paid 2:1 while the rest of the winning hands produce even pay.

Recommended Tips

Although the players will be able to surrender their Ante, the move should be generally avoided unless:

  • The dealer has 9, 10, or an Ace against the player’s hard 16 that does not consist of two 8s
  • The dealer has 10 against the player’s hard 15

Otherwise, players should:

  • Hit on soft 15, hard 8 or a lower value hand
  • Stand on soft 18, hard 17 or higher hands
  • Stand on hard 12 – 16 if the dealer’s up card is 2 - 6
  • Double on 10 – 11 unless the dealer’s up card is higher, in which case, one should Hit
  • Double on 9 or soft 16 - 18 if the dealer’s up card is 2 - 6

Split Aces and 8s

Split 2-2, 3-3, 6-6, 7-7, or 9-9 if the dealer’s up card is 2 - 6

Blackjack Super 21 Summary

Even though the natural Blackjack payout is only 1:1, the Super 21 variant compensates for the reduced payout by increasing the rate for the 6-card hands, as well as for the diamond natural Blackjack. Another advantage is that these suited Blackjacks do not even require an extra side bet.

Overview of 21+3 Blackjack

The 21+3 side bet is optional, and its size does not need to be the same as the main bet. In order to play the side-bet, you need to participate in the main hand.

Placing a bet in the 21+3 square is all you need to do to participate. As soon as the deal is made, and before any player takes any actions the 2 player cards and the dealer’s up-card (or only card in European Blackjack) are compared to the pay table.

There are several variations of 21+3 payouts, the most simple pays from a ‘flush +pair’ and up, with 9-to-1 payouts in each case. When pairs are also included, this is hit more often, so the prizes are lowered to reflect this. There are 3-to-1 for all hands (pair, flush, straight, trips and straight flush) or there are staggered pay tables.

When the prizes are staggered, a straight flush or better can win significant money. Here is an example:

  • Flush – Pays 5:1
  • Straight – Pays 10:1
  • Straight Flush – Pays 35:1
  • Three of a Kind – Pays 33:1
  • Suited 3 of a Kind – 100:1

Keep in mind that depending on the pay table, the house edge can get as high as 13% for this side bet. You can find examples of games (depending on the number of decks in use) where this is around 2.78% instead.

Strategy for 21+3 Blackjack

It goes without saying that knowing the correct basic strategy of the base game is a prerequisite here. Without this you are just handing money to the house.

Your main ‘strategy’ decision over the long run with the 21+3 side-bet is whether to play or not. The house edge is bigger than in most base games. If you know this, then you get to decide whether the added interest and entertainment (and chance of a windfall win) are worth it to you. If the extra engagement from the 21+3 bet works for you – then you can simply add a little to your bankroll to cover this.

Card counters can beat this game by memorizing the suits as they are dealt. It is possible on some deals to find one suit over-represented as the shoe gets smaller – turning the edge positive for players. The expected hourly rate for this is very low compared to other forms of counting. Online the deck is shuffled after each hand, making card counting impossible.

Pros and Cons of 21+3 Blackjack

Adding a poker style hand to blackjack makes for an interesting variation – though I do wonder whether ‘purists’ in either discipline would approve! Depending on which of the pay tables you use there is the chance of a 9-to-1 or even bigger windfall. That elusive suited 3-of-a-kind (paying 100-to-1) would certainly be memorable.

Whether you participate depends on your attitude towards side-bets in general. Some players like these bets, and are happy to pay the extra house-edge for the chance of the occasional big win. Others scorn these bets as long-term losers.
