Super 21 is a variation of regular blackjack. Although it plays like blackjack, there are many different rules between the games. The main differences are in the payout of 21 totals. Instead of getting 3 to 2 on all your 21 totals, this game pays even money on 21’s, except 2 to 1 for blackjack in diamonds and five-card 21 totals (as long as you haven’t previously doubled down in the hand). Any total of 20 or less with six cards automatically pays 1 to 1, unless you’ve already doubled down.

The house is forced to hit on a soft 17, and you’re allowed to double down on any total. The casinos usually only use one or two decks to play the game, giving them an edge of 1.36% for one deck and 1.30% for two. It’s a fun change from the usual, but the odds are better with the original.
