A familiar name is not a complete specification
Older descriptions equated Super 21 with Super Fun 21. They share themes, but do not assume every implementation is identical. The linked Super Fun 21 analysis provides a useful comparison; the rules displayed by the exact Super 21 game remain the specification you need.
Start with what a natural earns
Variants in this family can reduce the ordinary natural payout while offering special wins or extra flexibility elsewhere. A natural that wins more often against dealer blackjack can still pay less in other cases. Compare the entire settlement rule, including suit-based exceptions, rather than only the phrase “player blackjack always wins.”
| Feature | Write down |
|---|---|
| Natural payout | Ordinary payout and any special suit exception |
| Automatic wins | Exact totals and card counts that qualify |
| Doubling | Permitted card counts and whether actions continue |
| Surrender | Timing, eligibility and treatment after doubling |
| Splitting | Resplits, split aces and bonus eligibility |
Why extra options need a different chart
If a game allows an action after more than two cards, or rewards reaching a particular card count, the hand’s composition can matter in a new way. A standard total-only chart was not designed to account for those extra rewards and choices. More permissive rules do not make any arbitrary action profitable.
Try comparing two hypothetical payout sheets. On one, a $10 natural pays $15 profit. On the other, an ordinary natural pays $10, but some special hands receive extra awards. You can calculate the $5 difference on that event immediately; determining the overall return requires probabilities for all the special outcomes.
The game has several automatic wins. Does that prove a lower house edge than ordinary blackjack?
No. Automatic wins must be weighed against reduced payouts and other rule changes. Count the full set of outcomes, not just the favorable features.
This revision removes generic minimum and maximum bets and unsupported availability claims. Use the variant comparison to organize the differences, then select a strategy for the exact rules.
