Introduction

What Is Super Fun 21 and What Makes It Different?

Super Fun 21 is a special variant of blackjack that keeps the classic rules intact while adding exciting new features. Designed by Howard Grossman in 1995, the game quickly gained popularity in Las Vegas and casinos around the world.

The biggest difference from standard blackjack is that in Super Fun 21, players can Double Down on any number of cards, Surrender at any point, and — most notably — always receive a 2:1 payout for a blackjack in the Diamond suit.

The Super Fun 21 section on the c666k platform provides detailed rules, special hand payouts, and strategy tips. The game can be played with one or more decks, though a single deck is most common.

Key Differences

How Super Fun 21 Differs from Classic Blackjack

Players familiar with Classic Blackjack will find Super Fun 21 easy to pick up. That said, knowing the key differences in advance will help you keep your strategy on track.

1

Double Down at Any Time

In Classic Blackjack, Double Down is only allowed on the first two cards. Super Fun 21 lets you Double Down with any number of cards in hand — a significant advantage for the player.

2

Late Surrender Always Available

You can Surrender at any point — even after a Double Down. This gives players the option to recover half their bet when the situation looks unfavorable.

3

Diamond Blackjack Special Reward

A blackjack formed with an Ace and a 10-value card in the Diamond suit (♦) always pays 2:1, regardless of what the dealer holds. Blackjacks in any other suit typically pay 1:1.

4

Five-Card 21 — Special Payout

Reaching exactly 21 with five or more cards earns a special payout. Five Diamond-suited cards totaling 21 yields the highest reward.

5

Can Hit After Splitting Aces

In standard blackjack, you typically receive only one card after splitting Aces. In Super Fun 21, you can draw additional cards after splitting Aces, giving you more chances to build a strong hand.

6

No Push on Dealer Blackjack

In classic blackjack, both parties having blackjack results in a Push (tie). In Super Fun 21, if the dealer has blackjack, the player loses — with the exception of Diamond Blackjack.

Payout Structure

Special Hands & Payouts in Super Fun 21

One of the most exciting aspects of this game is its special payout structure. The table below lists payouts for various hands — keep in mind that these ratios may vary slightly across different platforms.

Special Hand Payouts
♦ Diamond Blackjack (Under Any Circumstances) 2:1
♦ 5-Card 21 (Diamond) 2:1
5-Card 21 (Other Suits) 3:2
21 with 6 or More Cards 3:2
Standard Blackjack (Other Suits) 1:1
Standard Win (excluding 21) 1:1
Push (Tie) Bet Refund

Payout ratios may vary by variant and platform. Always check the game rules before playing.

Diamond 21 Details

The most premium hand in Super Fun 21 is the "Diamond 21." To achieve it, every card in your hand must be from the Diamond suit (♦) and the total value must equal 21.

Full Diamond Hand
All cards ♦ suit and total = 21, highest payout
Payout Even if Dealer Wins
Diamond Blackjack pays 2:1 even if the dealer also has Blackjack
Multi-Card Version
21 with five or more Diamond cards — your shot at the top payout

Rules

How to Play Super Fun 21

The core structure follows classic blackjack, but there are a few special moves to be aware of. Here is a step-by-step breakdown for new players.

1

Place Your Bet

Before the game begins, place your bet within the table's Minimum and Maximum limits. If a Side Bet option is available at this stage, you may choose to include it.

2

Card Deal

The player receives two cards (both face-up). The dealer gets one face-up and one face-down card. Use the value of the face-up card to guide your next decision.

3

Consider Insurance or Surrender

When the dealer's face-up card is an Ace, you have the option to take Insurance. Surrendering at this stage returns half your bet.

4

Hit, Stand, Double, or Split

Based on the strength of your hand, choose to Hit (take another card), Stand (keep your hand), Double Down (double your bet), or Split (separate a pair into two hands).

5

Dealer's Turn

Once the player's turn ends, the dealer reveals their face-down card. The dealer must Hit up to Soft 17 and Stand on Hard 17 or higher.

6

Results & Payouts

The player wins if the dealer busts or the player's hand is higher. Special hands (Diamond 21, 5+ cards to 21) qualify for higher payouts.

Strategy

Basic Strategy for Super Fun 21

Basic strategy from classic blackjack is largely applicable here, but it needs to be adjusted to account for the unique rules of Super Fun 21.

When to Double Down

Player's Hand Dealer's Card Decision
Hard 9 3–6 Double
Hard 10 2–9 Double
Hard 11 2–10 Double
Soft 13–15 4–6 Double
Soft 16–18 3–6 Double
Any Hand (Multiple Cards) Weak Dealer Card Consider

Split Strategy

Pair Dealer's Card Decision
Aces Any Always Split
8s Any Always Split
9s 2–9 (except 7) Split
7s 2–7 Split
10s Any Do Not Split
5s Any Do Not Split

Surrender Strategy

Consider Surrender when holding Hard 15 or Hard 16 against a dealer showing 9, 10, or Ace. Saving half your bet is the smarter play in the long run.

Track the Diamond Cards

Keep track of how many diamond-suit cards have been used in the single deck. If the odds of hitting a Diamond 21 look favorable, adjust your strategy accordingly.

Five-Card Goal

If you receive low-value cards (A, 2, 3, 4, 5), aim to build a five-card 21 — this creates the opportunity for a special payout.

Budget Planning

Set a firm budget before each session and commit to not exceeding it. Gaming is for entertainment — not as a source of income.

Comparative Analysis

Super Fun 21 vs. Classic Blackjack

A side-by-side look at the key differences between the two games makes it easy to decide which one suits you better.

Features Super Fun 21 Classic Blackjack
Blackjack Payout 1:1 (Diamond = 2:1) 3:2
Double Down On Any Number of Cards Typically on First 2 Cards Only
Hit After Split Aces Allowed Generally Not Allowed
Late Surrender Even After Double Down First 2 Cards Only
5+ Cards to 21 Special Payouts Standard 1:1
Diamond Suit Advantage Yes (2:1 Payout) None
Number of Decks Typically 1 Typically 6–8
House Edge Slightly Higher (Lower with Correct Strategy) Generally Lower

Super Fun 21 carries a slightly higher House Edge due to its 1:1 blackjack payout, but the special payouts for Diamond Blackjack and 5+ card 21s, combined with the extended Double Down flexibility, make it a strategically compelling game.

Card Values

Card Values in Blackjack

Card values in Super Fun 21 follow the same rules as Classic Blackjack. The table below serves as a quick reference for new players.

2–9
Equal to Face Value
2 means 2, 3 means 3 — face value, straightforward
👑
King = 10
All face cards (K, Q, J) are worth 10
👐
Queen = 10
Carries the same value of 10 as a King
♠
Jack = 10
Third Face Card, Value 10
♦
10 = 10
Flat value of 10 — especially significant in the Diamond suit
A
Ace = 1 or 11
The most flexible card — counted as whichever value benefits the hand most
Soft Hands vs. Hard Hands

Soft Hand: A hand containing an Ace that can be counted as 11 without exceeding 21. For example: A + 6 = Soft 17.

Hard Hand: A hand with no Ace, or where the Ace must count as 1. For example: 10 + 7 = Hard 17.

Common Mistakes

Common Mistakes New Players Make

Avoiding these mistakes — learned from experienced Super Fun 21 players — will significantly improve your overall game experience.

Expecting the same Blackjack payout as in standard Blackjack
In Super Fun 21, a blackjack pays 1:1 (except Diamond). Rather than expecting 3:2, focus your strategy on landing the special hands.
Not Using the Double Down Option
While the option to Double Down is available at any time, many players never use it. Failing to Double Down in strategically favorable situations means leaving a key advantage on the table.
Splitting 10s or 5s
There's no reason to break up a strong hand worth 20. Even a 5+5=10 hand is better served with a Double Down than a Split.
Overlooking the Surrender Option
Forcing play with Hard 16 against a dealer's strong card is a losing approach over time. Surrendering to save half your bet is the wiser decision.
