How to Play Super 21 Online
The gameplay of Super 21 is nearly identical to standard online blackjack, which means you’ll face off against the dealer head-to-head in single-player format. Follow through a hand start to finish in the list below.
Place Your Bets
Before you get cards, you need to ante up. Click on the chips that correspond to how much you want to stake and move them to the betting area.Dealing the Cards
After the money is in the middle of the table, the dealer distributes the cards. They give you two cards face-up, followed by two cards to themselves, one face-up and one face-down.Hit, Stand, Double, Split, or Surrender
Based on the cards you can see, you need to decide whether to take more cards or not. You can hit for an additional card or stand if you think you have the win locked down.
Your choice to double or split is a little different in Super Fun 21. You can double down with any number of cards and even double on split hands. You can also split aces and split a hand made from a split.
If you think you’re going to lose, you can save half of your wager by choosing to surrender at any time.The Dealer Completes Their Hand
After you’ve finished making your decisions and stand on your cards, the dealer will finish their hand. They will hit and eventually stand or bust based on a standard set of house rules.Deciding Winners
At the end of a round, the dealer determines if you beat the house. Different payouts depend on your hand and how many cards you took before standing.
Super Fun 21 Strategy
Your typical blackjack strategy chart doesn’t apply to this game. The five and six-card hand bonuses add a little bit of variance after each hit. Let’s look at some of the unique situations specific to Super 21.
Bonus Hands
The bonus hands paying out at 2:1 make for some interesting decision-making. Let’s look at a player’s four-card hand of 15 into a dealer showing a 4.
In traditional blackjack, you would stand. The chances are good that the dealer has 14 and has to hit and possibly end up busting.
With the same situation in Super 21, you should hit. You have a shot at a higher payout if you take just one more card and don’t bust.
Surrendering
The late surrender rule is not present in standard blackjack. You can use it at the right time to save half of your ante bet for the next hand.
If you have a 15 in standard blackjack and the dealer shows an ace, you have to hit. It’s the only way you have a shot at winning the hand.
In Super 21, the correct play is to surrender with two or three cards. You can save some money for a shot at a better payout in the following round.
Doubling Down
The five and six card wins also affect when you double-down in Super 21 blackjack. Remember, you only get a single extra card for more money.
In regular blackjack, when you have a small total after three cards, you should double-down. You probably won’t bust and stand to win more.
In Super Fun 21, the player simply hits in hopes of landing one of the multi-card winners. They could get a 2:1 payout without the added stakes.
Winning Strategy Cheat Sheets
Super 21 has a house edge under 1.5% if you follow the suggestions in these four charts. If you split a pair, just treat both new hands the way you would play a single set of cards.
Find your hand’s total on the left side and the dealer’s up card in the top row. Make sure you read the correct sheet based on how many cards you have at the time.
