Blackjack side bets and game variants

The extra circles on the felt and the games with new names. What each one pays, what it costs you, and which are worth knowing.

Every house edge on this page is from the Wizard of Odds, which analyzes each bet’s paytables. A bet’s cost depends on its paytable and the number of decks, so the same name can cost very different amounts at two casinos. Read the paytable printed on the table.

Why side bets cost so much

Standard blackjack, played by the book, costs you about 0.4% of what you bet: 40 cents per $100. A side bet is a separate wager on the same deal, usually on whether your first cards, or yours and the dealer’s together, make a particular combination. They pay big multiples, 9 to 1 or 100 to 1, which makes them fun. But no decision you make changes the odds, and the payouts are set well below the true odds. Most cost 3% to 10% of every bet, and some cost far more.

A $5 side bet every hand at a 6% edge costs about as much as a $75 main bet played by the book.

The common side bets

BetWhat winsHouse edge
InsuranceThe dealer has blackjack when showing an ace. Pays 2 to 1.About 7.4% with six decks
21+3Your two cards and the dealer’s upcard make a three-card poker hand: flush, straight, three of a kind or straight flush.3.2% (six decks, all pay 9 to 1) to 13.4% (“Xtreme” paytable)
TriLuxThe same three cards make a flush, straight, three of a kind or straight flush. Common at Seminole Hard Rock casinos.3.2% to 23.3% (six decks), by paytable. A flat 7 to 1 on two decks costs about 7.3%
Perfect PairsYour first two cards are a pair. Pays most for an identical pair, less for same color, least for mixed.2.2% to 8.1%, by paytable
Match the DealerOne of your first two cards matches the dealer’s upcard. More if the suit matches too.3.3% to 4.8%
Lucky LuckyYour two cards and the dealer’s upcard total 19, 20 or 21, with bonuses for 7-7-7 and 6-7-8.2.7% (six decks)
Royal MatchYour first two cards are suited. Pays most for king and queen of the same suit.6.7% (six decks)
Buster BlackjackThe dealer busts. Pays more the more cards the dealer took.6.2% (six decks, dealer hits soft 17)
Lucky LadiesYour first two cards total 20. Pays most for two queens of hearts with a dealer blackjack.17.6% to 24.7%
Super 4 ProgressiveThe dealer shows an ace, and the four cards (yours and the dealer’s) make a poker hand. A flat $5 bet with jackpots.Returns 53% to 65% before the jackpot meters, so 35% to 47% before jackpots
Progressives (Blazing 7s, Blackjack Match Progressive and others)Big jackpots for rare hands, such as three suited 7s.Depends on the jackpot’s current size; usually high

The poker side bets, 21+3 and TriLux, are the ones where you win when your cards and the dealer’s make a poker hand. They’re the most popular, and their best paytables are among the cheaper side bets. Still, even their cheapest paytables cost six to eight times what the main game does. Vegas Advantage calls two newer games, Bonus Spin and Lucky Cat, the worst blackjack games in Las Vegas: both make a side bet part of the price of playing.

Blackjack variants

Variants change the main game itself, usually giving you something and taking something back. The basic strategy on this site is for standard blackjack; each variant has its own.

GameWhat’s differentHouse edge
Standard blackjackSix decks, dealer stands on soft 17, 3 to 2, double after split. What the trainer deals.About 0.4%
Double UpIf the dealer finishes on 16, bets push (except a player 21). You can “double up” on two cards, even after a split. Pays 3 to 2.0.32% (dealer hits soft 17)
Spanish 21All four 10s are removed from each deck, which hurts you. In return: a player 21 always wins, bonuses for five-card 21s and 6-7-8, late surrender, and surrender after doubling.0.40% (stands on soft 17) to 0.76% (hits soft 17, no redoubling)
Blackjack SwitchYou play two hands and may swap their second cards. Blackjack pays only even money, and a dealer 22 pushes.0.58% (dealer hits soft 17)
Free BetFree doubles on hard 9, 10 and 11 and free splits on most pairs: the house puts up the extra bet. A dealer 22 pushes, which takes it back.1.04% (six decks, dealer hits soft 17)
6-to-5 blackjackStandard rules, but a blackjack pays 6 to 5. Often dealt as single-deck, which sounds better than it is.About 1.4% more than the same game paying 3 to 2

Double Up beats a typical shoe game, and Spanish 21 with good rules about matches one, if you learn their strategies. Free Bet feels generous and costs more than double a standard game.
