Blackjack presents casino operators with something of a puzzle. It's the
most popular casino table game, and has been since it overtook craps
roughly 40 years ago. But it also has a low house edge, half a percent
or so with a basic strategy that's not all that difficult to learn.
They don't design games with house edges that narrow anymore. The house
edges at newer games mirror the 2 to 2.5 percent edge faced by a
blackjack player who hasn't taken the time to learn basic strategy.
Edges are 5.2 percent of the ante or 2.6 percent of total action at
Caribbean Stud, 3.5 percent of one bet or 2.8 percent of total action at
Let It Ride, 2.3 percent in the Pair Plus option and 3.3 percent of the
ante or 2 percent of total action in Let It Ride. For the average
player, those games aren't much worse than blackjack, but they don't
give the informed player a chance to narrow the gap.
What the casinos would really like is a way to increase their edge at
blackjack. One of they ways they try is to add side bets onto the
game--bets on whether the player or dealer with have a blackjack, bets
on whether the player's first two cards will be of the same suit, bets
on how many 7s the player will draw. Such side bets almost invariably
have a much higher house edge than the basic game. They also have a
short shelf life as players discover they're losing their money faster
than they do without the side bet.
When you find yourself at a table offering one of the wagers listed
here, remember that the basic strategy for side bets at blackjack is
almost always not to make them.
21 Madness: This probably is the most widely available side bet
in blackjack for the time being. The player makes a $1 wager in addition
to the regular blackjack bet. Then, if the player is dealt a two-card
21, he or she gets to push a button to start a lighted display, which
stops to reveal a bonus payoff from $5 to $1,000. Blackjacks occur about
once per 21 hands, so this would be a break-even bet if the average
payoff was $21. We don't know for sure what the average is--the lighted
display is governed by a slot machine-like random number generator. But
observation by a team in Australia suggests the average is $16, which
would leave a house edge of 23.8 percent. That's not necessarily the
case here. The average payoff could be higher or lower. Still, this
looks like a bet to leave alone.
21 + 3: Invented by Derek Webb, the Englishman who devised Three
Card Poker, 21 + 3 has become popular in the South and has started to
make inroads in Las Vegas. The "21" stand for blackjack, and the "+ 3"
is for a three-card poker hand consisting of the player's first two
cards and the dealer's face-up card. If those three cards yield a flush,
straight, three of a kind or straight flush, the player is paid 9-1 on
the side bet. The house edge is 3.2 percent, making 21 + 3 one of the
better side bets, although still not as good as sticking to regular
blackjack.
Progressive Blackjack: Mikohn Gaming, which distributes Caribbean
Stud, Caribbean Draw and other table games with progressive jackpots,
developed this side bet that pays off according to the number of Aces in
the player's hand. It involves a $1 bet in addition to a regular
blackjack wager. The player is paid $3 if the hand includes one Ace, $15
for two Aces of different suits, $50 for two suited Aces, $200 for three
unsuited Aces, $1,000 for three suited Aces, $2,000 for four unsuited
Aces and the progressive jackpot, which starts at $25,000 for four red
or four black Aces. At the beginning jackpot of $25,000, the house edge
is a lofty 53 percent. Ouch.
Royal Match: Here's one that has come and gone in the Chicago
market. It still shows up in other jurisdictions. The side bet pays off
if the player's first two cards are of the same suit, with a larger
payoff for King-Queen of the same suit--a "Royal Match." The most common
version pays 2.5-1 on most matches, and 25-1 on a royal match. Suited
hands are more common with more decks in play, so the house edge at
Royal Match actually decreases as the number of decks increase. The
house edge in this version, when it was played with six decks at
Harrah's Joliet, was 6.7 percent. In a single-deck game, the house edge
would have been 10.9 percent.
There's a higher-paying version of Royal Match, which cuts the return on
suited King-Queen to 10-1, but raises other matches to 3-1. On that one,
the house edge is 3.8 percent on a single-deck game, but the player
actually gets a 1.1 percent edge on a six-deck game. That doesn't
accomplish the casino goal of padding the house edge, so that's one side
bet you'll probably never see.
