Super Fun 21

Introduction

Super Fun 21 is a variant of the standard Blackjack game.  Super Fun 21 is known as ‘Blackjack Super 21’ at Playtech casinos and ‘Super 21’ at RealTime Gaming.

We are currently aware of Super Fun 21 being offered by the following online casino softwares – Microgaming, OpenBet, Playtech and RealTime Gaming.



Play Structure

Differences to standard Blackjack and rules that are standard to the online game;

 

·         Blackjack pays 1 to 1.

·         Player Blackjack beats dealer Blackjack.

·         Player may Double at any point before Standing or Busting.

·         Player can Double once per hand.

·         Player can Surrender a hand at any point before Standing or Busting.

Winning Strategies

Offline

Super Fun 21 is likely to be vulnerable to all of the standard advantage play techniques that standard Blackjack can be beaten by. Strategies for gaining an edge over this game are not in common circulation (we are aware of no publications discussing these issues either on or offline), but at least in the case of Card Counting we can confirm Super Fun 21 can be beaten (http://apheat.net/2012/09/08/card-counting-blackjack-variants/).

Online

There are several methods of legitimately gaining an advantage playing online Super Fun 21 games. By and large these involve the use of promotions, bonuses and comp point systems as the games by themselves – assuming the game is functioning in a correct fashion and there are no errors in the paytable – will not provide any additional information about the cards and shuffles after every hand.

It should be noted that online advantage play is not specific to Super Fun 21 and in recent years the wagering requirements for player’s choosing to play any table game has inflated to the point that Super Fun 21 is now often a sub-optimal choice for the player. For more information on beating online casinos see BeatingBonuses.com.
