- Blackjack side bets are additional bets that you can make while playing a traditional blackjack game either in a land-based or online casino.
- These side bets usually require a rather small wager and they generally have payoffs that are greater than the customary even-money blackjack payoffs.
- The majority of side bets do not involve any skill, which is one of the reasons for their popularity.
- The most player-friendly side bets have a relatively modest house edge (less than 5%).
There are new side bets being invented all the time in an effort to attract new blackjack players. Many of these side bets, however, never make it to the casino floor; however, some do, and the objective of this article is to explain the best side bets.
Many blackjack players like to make side bets for three main reasons:
- The cost to make a side bet is low (usually only one dollar).
- There is no skill involved.
- The payouts are greater than the customary even-money blackjack payouts.
MAKING A SIDE BET
There is usually signage on a blackjack layout, or on a placard that sits on the blackjack table, which specifies what side bet is being offered. You don’t have to make a side bet; it is an optional bet in addition to the bet that you would make on your hand in the main game.
Let’s assume you want to make a wager on the side bet. If so, after you make a bet on your hand, you would place your chip(s) in a betting spot on the layout designated for the side bet (see diagram).
Most casinos require that players must make a wager on their hand in the main blackjack game in order to make a wager on the side bet. Additionally, there is a minimum and maximum betting limit for the side bet. (The latter is usually posted on signage somewhere on the blackjack table; if not, simply ask the dealer what the betting limits are for the side bet.)
In general, blackjack side bets have a relatively high house edge, certainly higher than the main game, which can be less than 1% by using the basic playing strategy. However, if you want to try your luck at a larger payout, I would recommend you wager on the side bets that have the lowest house edge.
What follows is a list of the best side bets, specifically the ones with the lowest house edge.
This side bet is a combination of blackjack and three-card poker. It involves the player’s initial two cards and the dealer’s upcard, which combined, make a three-card poker hand.
In the original version of this side bet, if the three cards form a flush, straight, three-of-a-kind, or straight flush, the player wins and the payout is 9-1, yielding a modest 3.24% house edge. (Note: The latter is for a six-deck game; if it’s an eight-deck game, the house edge is only 2.74%, and with four-decks, it’s 4.24%.)
Nowadays, there are versions of 21+3 in land-based and online casinos that have a varied pay table such as the one below.
(Note: Unlike a five-card poker hand, with a three-card poker hand a straight pays more than a flush.)
|Suited Three-of-a-Kind||100 to 1|
|Straight Flush||35 to 1|
|Three-of-a-Kind||33 to 1|
|Straight||10 to 1|
|Flush||5 to 1|
With the above pay schedule in a six-deck game, the house edge is 4.14% (Note: If fewer decks are used, the house edge increases to 7.76% for three-deck game. If the game uses eight decks, the house edge is only 3.18%).
There are other pay tables in land-based and online casinos and the house edge varies depending upon the payouts for each of the above hands. I don’t have the space to list them all but one source to check is the 21+3 page on wizardofodds.com.
(Note: I would also recommend the article written by Eliot Jacobson on counting systems for 21+3 that target flushes.)
This side bet only involves the player’s initial two cards and it wins if the two cards are a pair (it automatically loses if the initial two cards are not a pair). There are three types of pairs that have a payout.
- Mixed Pair (Two cards of the same rank but different color: for example, queen of clubs and queen of diamonds).
- Colored Pair (Two cards of the same rank and color; for example, queen of hearts and queen of diamonds).
- Perfect Pair (Two identical cards; for example, two queens of spades).
The payouts vary from one casino to another but the most common are as follows (for an eight-deck game):
|Perfect Pair||25 to 1||30 to 1||25 to 1|
|Colored Pair||12 to 1||10 to 1||15 to 1|
|Mixed Pair||6 to 1||5 to 1||5 to 1|
|House Edge (8 decks)||4.09%||3.38%||2.17%|
As shown in the table, the house edge varies from 2.17% to 4.09%.
This side bet is based on the player’s initial two cards’ being suited. There are different payout schedules and number of decks of cards. The two most common in land-based and online casinos are as follows.
|Easy Match||First Two Cards are Suited||2.5 to 1||10 to 1|
|Royal Match||First Two Cards are King and Queen||25 to 1||3 to 1|
Another version uses six-decks of cards with a 25 to 1 payout for Royal Match, 5 to 1 for Suited Blackjack, and 5 to 2 for all other matches. The house edge is a respectable 3.70%.
Note: There is a card counting system for the Royal Match in these two books: Beyond Counting by James Grosjean, and The Big Book of Blackjack by Arnold Snyder.
The above three blackjack side bets — 21+3, Perfect Pairs, and Royal Match — are the best side bets because of their lower house edge compared to other side bets. However, there are published counting systems for some of the latter side bets (with higher house edge) that could significantly lower the house edge or give the player the advantage (specifically for Over/Under 13, Super Sevens, and Lucky Ladies).
